Calculating Kinetic and Potential Energy

Front

What is the relationship between kinetic and potential energy?

Back

They are both forms of mechanical energy.

Front

How does the kinetic energy of an object change if its velocity doubles?

Back

It quadruples.

Front

What are the units for measuring kinetic energy?

Back

joules (J)

Front

If an object has a mass of 10 kg and a height of 20 meters, what is its potential energy?

Back

2000 joules.

Front

What is the formula for calculating potential energy?

Back

PE = mgh.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv^2.

Front

What factors affect potential energy?

Back

Mass and height above a reference point.

Front

What is gravitational potential energy?

Back

Potential energy related to an object's height in a gravitational field.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass if velocity is constant.
