Force and Motion

Front

What is Force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is Motion?

Back

The change in position of an object over time.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Gravity?

Back

A force that attracts two bodies towards each other, such as the Earth pulling objects towards its center.

Front

What is Friction?

Back

A force that opposes the motion of an object when it is in contact with another surface.

Front

What is Mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is Weight?

Back

The force of gravity acting on an object, calculated as mass times the acceleration due to gravity (Weight = Mass x Gravity).

Front

What is Acceleration?

Back

The rate at which an object changes its velocity, which can be a change in speed or direction.

Front

What is a Balanced Force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an Unbalanced Force?

Back

Forces that are not equal and can cause an object to start moving, stop moving, or change direction.
