Answer 2

1. First law: An object at rest stays at rest or continues moving with a constant velocity unless acted upon by a net external force.
2. Second law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
3. Third law: For every action, there is an equal and opposite reaction.

Answer 3

Newton's 1st Law of Motion

An object at rest remains at rest, and an object in motion remains in motion along a straight line until a net force acts upon it.

The boulder in your back yard is going to stay siting in the same spot until a net force acts upon it to move it.

If you throw a ball out of the air lock of a space ship, it will keep moving in a straight line at the same velocity until a net force acts upon it.

Newton's 2nd Law of Motion

The acceleration of an object is directly proportional to the Force applied to an object, and inversely proportional to the mass of the object.

Apply a force to a cart and it will accelerate.

Apply a larger force to the same cart and it will have a greater acceleration.

Apply a force to a cart and it will accelerate.

Load some bricks (mass) into the cart and apply the same force as before. The acceleration will be less.

Newton's 3rd Law of Motion

For every action, there is an equal and opposite reaction.

Take a skate board and place it at the base of a wall. Climb on the skate board, facing the wall. Put your hands on the wall and push (force) hard on the wall. You will roll backwards on the skate board. You applied a force to the wall, and the wall applied and equal and opposite force to you.

Answer 4

Motion of plane once the pilot changes the accelerator setting of engine is explained from the first law. Newton's First Law includes implications in regards to the basic symmetry of the World, in that circumstances of motion in a straight line has to be in the same way 'natural' to be at rest. If the object is at rest in a single frame of reference, it's going to appear to be moving in a straight line for an observer in reference frame that is moving through the object. The second law declares how the acceleration of the object depends upon two parameters the net force behaving upon the object and also the mass of object. Newton's third law is: The path of the force about the first object is actually opposite towards the path of the force on second object. Newton's third law is one of the most familiar. When 1 object puts a force on the 2nd object, the 2nd object also puts a force on first object. Both forces are equivalent in oriented and strength in opposite instructions. Newton's law of gravity identifies the desirable force in between all objects which possess mass. Knowing the law of gravity, one of many essential forces of physics, provides profound information to the way our Globe functions. In the bold, groundbreaking step, Newton mentioned that his gravity law labored for any 2 objects with the mass it applies for any motions on earth, as well as, any kind of motions in the space. He unified terrestrial and celestial physics and finished the procedure began by Copernicus of taking out the Earth from a distinctive situation or position in the Globe. Newton's Law of Gravity states a whole lot about this force in an exceedingly compact, elegant way. It states that any little bit of matter will really feel it whether it's charged or otherwise not (this sets it aside from magnetic and electrical forces which have an effect on only charged objects). Gravity is dependent only on masses of the 2 attracting objects as well as their distance from one another.

Answer 5

Newton's First Law of Motion is demonstrated by kicking a ball. The ball will not moved until the force of a kicking foot is applied. Newton's Second Law of Motion says you have to push a cinder block harder than you have to push a brick to get them to move at the same speed. Newton's Third Law of Motion is shown when a fireman gets knocked backwards after turning on the water hose.

Answer 6

The Three Laws of Motion as described by Matt Clark

There are three laws of motion as comprised by Sir Isaac newton, and they are (in order) as follows.

1)An obect at rest or in motion will stay at rest or in motion until acted upon by an outside force.

2)Force = Mass x Acceleration

3)Every action has an equal and opposite reaction

The examples of the laws are short and simple but I believe it may help shed some light and understanding to their meanings.

For all of you sports fans out there, I'll relate the examples to Baseball.

Now, that being said, for the first law, imagine a pitcher throwing a warm up pitch to the catcher. There are one of two things that can stop the baseball. The outside force stopping the baseball can be either the catcher catching it, draining the ball of the kinetic energy it possessed from being thrown by the pitcher, or, simply, the friction in the air. Air friction is everywhere, it's the reason we have drag. If a physical piece of matter doesnt stop the ball it would just keep traveling as if it were in space. No matter what is moving/at rest, if its energry changes from potention to kinetic or vise versa, the first law of motion has been applied.

Law number two is a simple equation stating the process to calulate force. If the pitcher throws the ball (for simple calculations lets say the baseball weighs two pounds) at 90 miles per hour, the force equals a 180 pound force. Now, if a machine shoots a fifteen pound medicine ball at the same speed, 90 miles per hour, it has a much larger force, a 1350 pound force. As you can see it varies on the weight of the object and how fast it is traveling. The equation can also go more in depth with drag and aerodynamics giving the force and kinetic energy will slowly or rapidly bleed off, depending on the situation.

Law number three, the most commonly known of the three laws, which talks about every action having and equal and opposite reaction. Batter up! Lets say our pitcher throws a fast ball and good ole Pete Rose hits a grand slam. Newton's third law at it's finest. The pitcher threw the ball, giving the ball action, and Rose hit it, giving it an equal, but opposite reation.

Answer 7

; First law : There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. This law is often simplified as "A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force." Newton's first law is often referred to as the law of inertia. Basically means. Without friction or outside force (like pushing or wind), an object, if moving, will continue moving in that direction at a constant speed or, if stationary, will remain stationary.

; Second law : Observed from an inertial reference frame, the net force on a particle is proportional to the time rate of change of its linear momentum: F = d(mv)/dt. This law is often stated as, "Force equals mass times acceleration (F = ma)": the net force on an object is equal to the mass of the object multiplied by its acceleration. This means, the amount of force needed to accelerate an object to X meters per second squared, is X times the mass of that object. Eg: to accelerate a ball 5 meters per second squared, and the ball weighs 2 kg, a force of 10 newtons is needed.

; Third law : Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence, "To every action there is an equal and opposite reaction." The most complicated to explain. Imagine a cannonball being fired out of a cannon. The cannonball requires 1000N of force to be fired out. This force pushes the cannonball out, but at the same time pushes the cannon back. Most of the time, the third law can also be seen as "recoil"

Answer 8

Newton's 1st Law: An object remains at a constant velocity or at rest (equilibrium) unless acted upon by an outside force.

Example: A car is traveling at a constant velocity. Disregarding friction and air resistance, the car remains at this speed unless you brake or accelerate.

Newton's 2nd Law: Force equals mass multiplied by acceleration.

Example: Use any object and multiply its mass by its acceleration. This will always equal the sum of the external forces. So, if an object is at zero acceleration it has no external forces acting on it.

Newton's 3rd Law: For every action, there is an equal and opposite reaction.

Example: Standing on the ground. You exert a force on the ground due to your weight and gravity, and the ground exerts an opposite force on you (the normal force).
