What is kinetic energy?

Back

The energy of an object due to its motion, calculated as KE = 1/2 mv².

What is potential energy?

Back

The energy stored in an object due to its position or state, calculated as PE = mgh.

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 the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
