21/22 Potential and Kinetic Energy Test Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What is mechanical energy?

Back

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

Front

How does height affect potential energy?

Back

The higher an object is positioned, the more potential energy it has due to gravity.

Front

What is the relationship between potential and kinetic energy in a pendulum?

Back

In a pendulum, potential energy is maximum at the highest points, while kinetic energy is maximum at the lowest point.

Front

What is work in terms of energy?

Back

Work is done when a force causes an object to move. It is a transfer of energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of potential energy?

Back

A rock at the edge of a cliff has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its motion.
