Front

What two factors determine kinetic energy?

Back

The object's speed and mass.

Front

What is kinetic energy?

Back

The energy an object has due to its motion, calculated as 1/2 × mass × speed².

Front

What is the unit of work?

Front

What does the term 'force' mean in physics?

Back

A push or pull on an object.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy.
