what is newtons first law


Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If an external force is applied, the velocity will change because of the force.

what is newtons second law


Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.

what is newtons third law



His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.

Describe what happens if you are riding a skateboard and hit something (like a curb) with the front wheels.

Your body will keep moving forward and fly off your skateboard since the curb only stops the board, not yourself.

Describe what happens if you try and push Mr. Larson. What happens if he pushes back?

If you put force on Mr. Larson, force will be put back on you. Because of Mr. Larson’s mass, you most likely will not have enough force to make him accelerate. If Mr. Larson pushed you, you most likely would move in the direction of the force since he has more mass.

What happens according to Newton if you let an untied balloon go?

Air will rush out of the balloon forcing the balloon to move through the air in the opposite direction, but equal in force.

what are 3 examples of newtons first law

A stationary object with no outside force will not move.

With no outside forces, a moving object will not stop

An object at rest stays at rest.

Using Newton’s laws explain why heavier objects require more force than lighter objects to move or accelerate them?

Something with more mass moving at the same acceleration as a lighter object would require more force to change its speed or change its direction. Our formula F=m x a is derived from Newton’s second law.

Describe why you hold your gun next to your shoulder while deer hunting.

When you pull the gun’s trigger, it forces the bullet out of the gun, but at the same time, the gun is forced in the opposite direction of the bullet (towards you). Your shoulder is a new force that is introduced in order to keep your gun from flying away from you.
