Forces, Newton's Laws, Mechanical Energy

What is Newtons first law?

• Force equals mass times acceleration.

• An object in motion tends to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.

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

• change in position of an object over time.

What is Newtons second law?

• Force equals mass times acceleration.

• the strength and vitality required for sustained physical or mental activity.

• An object in motion tends to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.

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

What is mechanical energy?

• sum of kinetic and potential energy in an object that is used to do work. It is also energy in an object due to its motion or position.

• change in position of an object over time.

• An object in motion tends to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.

• rate at which work is done

What is work?

• a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.

• a coherent, typically large body of matter with no definite shape.

• any interaction that, when unopposed, will change the motion of an object.

• there is a displacement of point of the application in the direction of the force.

What is weight?

• a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.

• a coherent, typically large body of matter with no definite shape.

• any interaction that, when unopposed, will change the motion of an object.

• there is a displacement of point of the application in the direction of the force.
