Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the principle behind the conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
