Front

What is kinetic energy (KE)?

Back

the energy of an object due to its motion

Front

What is potential energy (PE)?

Back

the energy stored in an object due to its position or state

Front

What happens to the kinetic energy of an object if its mass increases while its velocity remains constant?

Back

The kinetic energy will increase.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity)

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as height increases.
