Mechanical Energy

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What does force do to an object?

Back

Force can change the motion, direction, and speed of an object.

Front

What is speed?

Back

Speed is the amount of distance traveled over a time.

Front

What is direction in terms of motion?

Back

Direction is the path that an object follows when it moves.

Front

What is an example of kinetic energy?

Back

A ball rolling down a hill is an example of kinetic energy.

Front

What is an example of potential energy?

Back

A stretched rubber band is an example of potential energy.

Front

What is the difference between speed and velocity?

Back

Speed is how fast something is moving, while velocity includes both speed and direction.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases and its kinetic energy increases.
