Newton's Laws of Motion

By Ethan Hagmann

Newton's first law of motion says that an object in motion will stay in motion and an on object at rest will stay at rest unless acted on by an unbalanced force.

This picture represents Newton's first law because for the ball to move the player must kick the ball causing an unbalanced force that moves the ball in a certain direction. For the ball to stop moving an unbalanced force such as; gravity or friction depending on whether the ball is moving through the air or if it is on the ground. This represents inertia which is the tendency to resist a change in motion and as the mass of the ball the greater amount of inertia there is so that it requires a larger unbalanced force to cause the ball to change in motion when the ball has more mass.

Newton's second law of motion states that the force of an object is equal to it mass times it's acceleration.

This picture represents Newton's second law because as the apple's mass increases there will be a greater gravitational force on the apple. This causes the acceleration of the apple to increase and this causes the apple to have a greater force as it hits the ground. The apple moves because their is a gravitational force acting upon it so that the velocity of the apple has increased to increase the amount of force that the apple hits the ground with. This all shows that the mass of the apple times the acceleration of the apple equals the amount of force that the apple hits the ground with.

Newton's third law of motion states that for every action there is an equal and opposite reaction.

This picture represents Newton's third law because as the action on the one side of the lever there is an equal and opposite reaction on the other side of the lever to cause one side to move down with a certain amount of force and for the other side to go up with the same amount of force. Also the side that moves down on the lever is the action force while the other side that moves up is the reaction force.
