The three laws proposed by Sir Isaac Newton to define the concept of a force and describe motion, used as the basis of classical mechanics.

With poor language we cannot assess. Any way the objects speed goes on increasing

Always contrary to the motion.

The concept of inertia requires that a body maintains its state of motion, unless a force is applied to it. So, the presence of friction force in nature causes the body to cease its moviment , as expected by the first law. Thus, the analysis requires an abstraction though, in the sense that...

The first law of Newton is for any material, and it states that if the net force on an object is zero, the object will be at rest forever or will move with uniform velocity forever. In the case of a bicycle, the obviously known forces are gravitational force, the reaction force of the...

the greater the mass, the greater will be the inertia produced in the body when the force is applied on it.

Newton's first law of motion says only that it takes force to change the speed or direction of motion.

Net force ON the box is 10N to the right.

Average velocity = change in displacement/change in time

non contact force

a ball rolling without slippage down a ramp has two components, the mass accelerating in a straight line, and the mass also accelerating about an axis , like a flywheel (essentially adding more weight) the force required to accelerate a mass of 2 lb ( 0.9072 kg ) @ 12 (m/s)/s is: f = m * a f = 0...

Newtons first law of motion is also known as Law of inertia

Kate's inertial mass exerted a force on the safety belt, causing the safety belt to exert an equal and opposite force on Kate. It makes more sense vice versa, though. Kate's inertia caused her to continue to move forward even though the car was slowing down. The safety belt exerted a force back onto...

Deciding if an object is moving isn't as easy as it sounds. We can only discern relative motion and we have to use reference points. (A reference point is an object that is not moving that you compare to the other object.) An object is in motion when it's distance from the reference point is...

You can find out how long a spring has been stretched/compressed by knowing it's elastic constant and the force the spring is exerting trying to go back to it's original shape. F=K*x (Moore's law) F is the force exerted by the spring. K is the elastic constant. X is the displacement of the end of...

Newton's first law is about Inertia.It states that an object at rest will stay at rest unless an outside force acts on it and an object in motion will stay in motion unless an outside force acts on it.This means that an object at rest will never move by itself and an object in motion will never stop...

Force to lift something = (mass) times (gravity) Work (energy) = (force) times (distance) = (mass) x (gravity) x (distance) Power = (work/energy done) divided by (time to do it) = (mass) x (gravity) x (distance) / (time) = (100) x (9.8) x (2) / (4) = 1960/4 = 490 joule/sec = 490 watts ...

Motion is always compared to a reference point. If you and some friends are driving in a car at 60 mph from your reference point your friends do not appear to be moving, but if you are standing at the side of the road as the car goes by the passengers will appear to be moving at 60 mph.

Force = mass X accelerationThe bowling ball.

Yes....Yes, inertia is directly proportional to mass.

no, because friction is opposing to the direction of the force which makes object still in their position.

If you mean an external force when you say unbalanced forces, yes. Newton's First Law of motion is also known as law of inertia. Inertia is the movement of mass with out any external forces or influences acting on that mass.

Cut a bucket in half to form a trough.Then, drop a ball down the side of it.The ball will keep rolling until the friction it builds up stops it.

= the (square of the velocity (m/s) * drag coefficient ) newtons if terminal velocity is known (forces balanced , no further acceleration), drag coefficient can be found. say terminal velocity(tv) = 70 m/s, acceleration due to gravity(g) = 9.8 m/s^2, mass(m) = 80kg m * g (force down) = tv^2 *...

Assuming that nothing else changes, multiplying the mass x3 will result in multiplying the force x3. F = m*a --> (3m)*a = 3F

The net force is the vector sum of all the forces acting on the object....So that is...(20+10=30)N acting in the same direction.........

It would be 12 newton's because the first team has the force of 11 newton's so, the second team would need 12 newton's to win.

No, weight does not effect speed downhill because the acceleration is only due to gravity, which does not depend on mass of the body if friction is not present.

They would travel equal distances because equal amounts of force allows for an equal amount of acceleration.

When something is acted upon by an outside force so it would be like if you are swinging and a ball is thrown at you, you slow down because that ball hit you. More examples: The ever popular brake one. When you brake your car suddenly you go flying right? Well hopefully you'd be wearing your seat...

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Blood rushes from your head to your feet while quickly stopping when riding on a descending elevator. The head of a hammer...

You can use the Pythagorean theorem to solve for the actual height of the incline because you know they hypotenuse length of the triangle as well as the angle. sin(theta)*950 = _____( actual height of the ramp ) With this new height value you can determine the minimum work needed to push the car...

It is associated with the law of gravitational pull.

That's the 'net' force on the object.

1) Newtons first law2) Inertia3) Newtons first law of motion

the word is gravity

The force acting on you due to the gravitational attraction between you and the sun or the moon is not noticed because they're so much smaller than the gravitational force between you and the earth. If you don't notice the gravitational force between you and the earth, it's only because it has ...

F = m A 10 = 2 m m = 5 kg

It is Newton or Kgms -2

The action and reaction forces have equal magnitudes and opposite directions, so their vector sum is zero. We say the two forces are "balanced", and the net force on the book is zero, so the book doesn't accelerate.

potential energy can be decreased or increased depending upon the work being done on an object

Yes, it can. In fact, if it is moving and there is a zero net force, it will continue moving indefinitely, at a constant velocity (Newton's First Law).

its momentum remains unchanged, until decelerated by an impulse force, such as an airbag.

The net force is zero and therefore, there is no acceleration.

the direction of force of friction provided from earth is in its opposite direction.i.e the wheel and frictional force are both opposite to each other

In a controlled test condition (like crash tests on cars) an accelerometer is used to measure the rate of deceleration. It should be possible to estimate the deceleration following a collision if the speed of the vehicles at the moment of the collision is known. We could do this by measuring...

Law of inertia

you could use a spring balance kg * 9.81 = newtons

Frame Of Reference. which means a framework that is used for the observation and mathematical description

Acceleration is defined as the change in velocity divided by the time or a = (vf - vi)/tVelocity measures the speed and the direction of an object. In uniform circular motion, the object has the same speed but it is always changing direction and so, by the definition of acceleration, the object is...

Say a 14 year old girl was at a construction site and she was asked to move something like a 10,000 pound brick( one brick). She would be acting on it as the unbalanced force but they would still not change their position. so to say the girl would be doing everything she could to move that brick...

1000% know it is It will not move at all

When a volley ball hit by a player, the forces on the ball are not balanced, and the ball will accelerate in the direction of the force of the contact with the ball.(Even when the ball is in midair, the forces are not balanced because of gravity. In this case, the ball will accelerate down.)

Friction force is equal to the force applied only when the object is not moving or it is just beginning to slide. Once the object has started motion completely, it means that the force applied has exceeded the frictional force

F= m(v-u)/t or Ft= mv-mu... Impulse. Impulse= change in momentum. The unit of impulse is the newton second (Ns). Since this quantity is equal to change in momentum it means that momentum can also be expressed in Ns. Impulse=Ft=change in momentum.

Water has density and weight. The deeper you dive the more water you have pushing against your body. == Answer == Think of it like this young padawans: You place a book on your head, no big deal. For every foot that your imagination takes you deeper on a dive add one book. Is...

Force always acts on an object only

Its velocity is increasing or decreasing (its velocity is not constant).

Eventually, just about every kind of math there is. A fine example relates to Sir Isaac Newton, when he was working ontrying to connect his law of gravity with the motion of the planets. Heneeded a kind of math that didn't exist yet ... (actually, somebody else was in theprocess of inventing it,...

Consider this. If you ask somebody how far it is "from here to there", he/she would probably ask you where "here" is, and where "there" is. Here and there is the reference start and reference end point. Without a reference start and end, we would not actually know or have information we can relate...

your toe hurts because there is a reaction on the toe by the ball that is greater than the applied force

it is called Motion against gravity

both of the forces in balanced force or in opposite forces are equal in force and opposite in direction.

An object's inertia is the object's resistance to change in motion. Newton stated this principle as his first law of motion: "Every body persists in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by force impressed."...

The gravitational pull of the earth forms the centripetal force responsible moving satellites in orbit, gravitational force equals centripetal force numerically.

80 jules/20meters= 40Newtons

a book kept on a table. no change in its state of rest unless some external force applied.however in case of moving bodies no such easy example's there as friction always supplies the retarding force ultimately bringing body to rest.

Stopwatch and measuring device.

It will not only tend to remain in straight line motion at a constant speed, it will in fact always do just that, until an external force acts on it and causes it to speed up, slow down, or change direction. The general term for any of these effects is 'acceleration'.

Most modern ice makers require 35 to 40 psi water pressure to properly operate. Attempting to use less pressure will result in no ice at all or possibly causing the solenoid valves to not fully close, thereby causing your ice maker to over flow.Using a demand pump will solve this issue. A demand...

F = m a a = F/m = 100/20 = 5 meters per second 2 .

The acceleration of any object is proportional to the net force acting on it. If the net force drops by 50%, then so does the acceleration.
