KInetic and Potential Energy

Front

What is potential energy?

Back

The stored energy of an object due to its position or condition.

Front

What is kinetic energy?

Back

The energy that an object has due to its motion.

Front

What two factors affect an object's kinetic energy?

Back

Mass and speed.

Front

How is potential energy calculated for an object at height?

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 is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed.

Front

If an object is at rest, what is its kinetic energy?

Back

0 Joules.

Front

What happens to potential energy as an object falls?

Back

Potential energy decreases while kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 × mass (m) × speed² (v²).

Front

How does mass affect potential energy?

Back

Potential energy increases with an increase in mass.
