Energy Final

Front

What happens to the temperature of a substance as the average kinetic energy of its particles increases?

Back

The temperature of the substance increases.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the kinetic energy of a cheetah with a mass of 47.0 kg running at a speed of 31.0 m/s?

Back

22,584 Joules

Front

What type of energy is stored due to gravity?

Back

Gravitational Potential Energy

Front

True or False: Moving a book to a lower shelf decreases its potential energy.

Back

True

Front

What is the relationship between Power and Work?

Back

Power is the rate at which Work is done.

Front

Define Gravitational Potential Energy.

Back

Energy stored in an object due to its position in a gravitational field.

Front

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

Back

Joule (J)

Front

If a 10 kg object is lifted to a height of 5 meters, what is its gravitational potential energy?

Back

Potential Energy = mass (m) * gravity (g) * height (h) = 10 kg * 9.81 m/s² * 5 m = 490.5 Joules.

Front

What is the difference between kinetic energy and potential energy?

Back

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