06c - Calculating Kinetic and Potential Energy

Front

Energy can be _____________ or changed from one type to another.

Back

transferred

Front

What is the formula for calculating gravitational potential energy?

Back

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

Front

What is the unit of energy in the International System of Units (SI)?

Back

Joule (J)

Front

What type of energy is stored in a battery?

Back

Potential Energy

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 0.5 × mass (m) × velocity (v)²

Front

A ping pong ball has a mass of about 2.45 g. If it is hit with a speed of 4.0 m/s, what is its kinetic energy?

Back

0.0196 J

Front

What is the kinetic energy of a soccer ball with a mass of 0.8 kg kicked at 10 m/s?

Back

40 J

Front

What is the gravitational potential energy of an object with a mass of 10 kg at a height of 5 m?

Back

490 J (using g = 9.8 m/s²)

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed or transferred.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.
