Energy Review

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How do you calculate Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 * mass (m) * velocity (v) squared (v²).

What is the Kinetic Energy of a 2 kg volleyball moving at 25 m/s?

Back

625 J (KE = 1/2 * 2 kg * (25 m/s)²).

Front

What type of energy is associated with an object's position?

Back

Potential Energy.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state.

Front

What is the difference between Kinetic and Potential Energy?

Back

Kinetic Energy is energy of motion, while Potential Energy is stored energy based on position.

Front

What is an example of an object with high Potential Energy?

Back

A book on a high shelf has high Potential Energy due to its elevated position.

Front

What device converts electrical energy into light and sound energy?

Back

An alarm clock.

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) * gravitational acceleration (g) * height (h).

What is the Kinetic Energy of a 20 kg bicycle traveling at 10 m/s?

Back

1000 J (KE = 1/2 * 20 kg * (10 m/s)²).
