Newtons Laws of Motion

That tendency is called inertia. According to Newton's first law of motion, an object will remain at rest or continue moving in a straight line at a constant speed unless acted upon by an external force.

The forces are balanced because they are falling at a constant speed. According to Newtons first law of motion an object will keep moving unless an unbalanced or net force acts upon it.

If we may step in here for the novel purpose of answering the question . . .

The balanced forces on an object that is falling with constant speed are typically

the force of gravity (the object's 'weight') and the equal and opposite force of

air resistance.

The basic principles of RADAR are . . .

-- When radio waves encounter any change in the physical properties of the

medium through which they're moving, some of their energy is reflected from

the boundary.

-- The part of the energy that reflects back in the direction from which it came

can be detected at the location of the source, after a period of time that's directly

proportional to the distance between the source and the reflection point.

Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This law describes the concept of inertia, which is the tendency of an object to resist changes in its motion. In practical terms, it means that objects will continue moving at a constant velocity or stay at rest unless a force is applied to change their state.

Yes, momentum is a conserved quantity in closed systems where no external forces act. This means that the total momentum before an interaction is equal to the total momentum after the interaction. This principle is known as the law of conservation of momentum.

Yes, Newton's first law states that an object will remain at rest or in uniform motion unless acted upon by an external force. This law is often associated with inertia, which is the tendency of an object to resist changes in its motion.

There is no problem in this case from Newton's third law because the collision is not happening instantly.

During the collision the mud is flattened and slowed by a reactive force from the wall (according to the third law) and the kinetic energy that is lost is converted to heat in the wall and the mud and also the deformation of the mud.

After the collision no speed remains and the mud sticks to the wall. The problem is that you forgot to consider the time of the collision and that the mud itself is not a rigid object; it can absorb energy.

Similarities:

1. All three laws describe the relationship between an object's motion and the forces acting on it.
2. They apply to all objects, regardless of their size or speed.

Differences:

1. The first law (inertia) states that an object at rest stays at rest unless acted upon by a force, while the second law (F=ma) describes how the acceleration of an object is related to the net force acting on it.
2. The third law (action-reaction) states that for every action, there is an equal and opposite reaction force, highlighting the interaction between two objects.

An object traveling in one direction can be accelerated in another direction by applying a force in the desired direction. This force will cause the object's velocity to change, leading to acceleration in the new direction. The acceleration will depend on the magnitude and direction of the force applied.

A speeding missile, or any moving object, has momentum. Force was used to cause it to move in the first place. If this object strikes another object, it will then exert a force on the object that it strikes.

When an object is in motion, such as a falling pencil, it posseses energy, there fore something must absorb it's energy to stop it to a rest. (example- a car in motion stops by the brAke absorbing it's energy). But energy is never destroyed or created, it can only be transferred from one form to another (example- the cars brakes heat up when used because the cars energy is being transferred to heat energy). So, the instant the falling pencil strikes the ground, it stops

falling correct? But the energy the previously falling pencil possess must be transferred to another form of energy the energy can't be

"lost" right? So what happens is some of the energy is converted to heat when it strikes the ground, you may not believe it but there is heat when it hits the ground because of friction. Furthermore, some of the energy is also converted to sound energy. (the pencil makes a sound when it hits the ground and sound is energy) but the heat and the sound energy combined is not enough to transfer all of the energy of the falling pencil. So where does this little extra energy go? You guessed it! Back up! It hits the ground, it goes back up because not all of it is transferred to another form such as sound or heat so it must go back up- or as you said, bounces. Hope this helped you understand.

When two bodies attract each other the larger one exerts the larger force because it contains more matter. Every particle of matter in the Universe is attracting every other. So the Earth exerts the stronger force on the Moon. The Space explorers have shown that on the Moon they weigh about one sixth of what they weight on Earth.

Yes, it is possible for the impulse of force to be zero even if the force is not zero. This can happen if the force is applied for such a short period of time that the area under the force-time graph, which represents impulse, is zero.

Newton's laws of motion are made when thinking that the objects are in a vacuum.

Living on Earth, we have an atmosphere (air).

So the atmosphere will interrupt all the objects tested.

For example, when throwing a ball in space, the ball will continue on forever, because there is nothing to disturb it. Until off course something does disturb it, like a meteor or a black hole.

But throwing a ball here on Earth, it will only fly for a bit. There is the air that will cause friction and make it slow down (even though it is very small) and most important of all, gravity.

newton said that if no external force act upon any moving object than it will move through out.. but in actual world .. there are lot of external forces.. and those are frictional forces.. so newton first law holds..

The weight (or mass) of the body affects the force needed to propel it through the air. A heavier body requires more force to achieve the same speed as a lighter body. Additionally, air resistance increases with speed, so a heavier body may experience greater resistance at higher speeds.

mass(kg) = force(n)/acceleration(m/s^2),

mass =1000/9.81

mass = 101.94 kg

We're not aware of any [non-relativistic] situation in which it appears to fail.

We'd appreciate the questioner coming back and describing one, for discussion.

What do you mean by "high speed" ? In what way does the formula not work ?

Work done by a force (W) = Force (F) x distance (m)

W = 22 x 18 = 396 Joules

According to the law of conservation of Energy, the total energy of a closed system is constant, but can change from one type to another.

Therefore, the work given to the object must be converted into the kinetic energy of the object.

So,

Increase in Kinetic energy = work done = 396 Joules

You can't, unless you know both of their directions.

-- If they're in the same direction, then the net force is 10N in that same direction.

-- If they're in opposite directions, then the net force is zero, and the direction

doesn't matter because there's no net force.

-- Depending on their directions, those two forces can combine to produce a

net force of anything between zero and 10 N, in any direction. So you need to

know their directions in order to figure out what the net force is.

Yes, an object can be in equilibrium if it is acted on by two forces that point in mutually perpendicular directions. This is known as mechanical equilibrium, where the vector sum of all the forces acting on the object is zero, and the object does not accelerate.

Since the bed is uniform we can assume that each leg carries exactly 1/4 the total force. Force is equal to mass times the acceleration of the object. The bed, hopefully being at rest, is only effected by gravity. So its acceleration is 9.8 m/s2 downward.

F = 45Kg * 9.8 m/s2

This will give you an answer in Newtons (Kg*m/s2) then divide by 4.

If a net force of 5 N acts on a hockey puck, it will accelerate according to Newton's second law (F=ma), where F is the force, m is the mass of the puck, and a is the acceleration. The puck will move in the direction of the force, increasing its velocity over time as long as the force continues to act on it.

Momentum is mass multiplied by velocity. The formula for momentum is: p (momentum)= m (kg ) x v (meters/second). So in this case, the mass is 9000 kg and the velocity is 3 m/s, so its momentum is 27000 kg-m/s, or N-s.
