Force and Motion Flashcard

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 friction?

Back

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

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What does it mean for forces to be balanced?

Back

When two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

When two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion.
