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 balanced force?

Back

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

Front

What is unbalanced force?

Back

Forces that are not equal, causing a change in the motion of an object.

Front

What is friction?

Back

A force that opposes the motion of an object, caused by the contact between surfaces.

Front

How does mass affect motion?

Back

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

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is speed?

Back

The distance an object travels per unit of time.

Front

What is the relationship between force and motion?

Back

An unbalanced force acting on an object causes it to accelerate, changing its motion.

Front

What happens to motion when friction is reduced?

Back

The object will move faster because there is less resistance to its motion.
