Front

The sum of the kinetic and potential energy in a system is known as the system's total ________ energy.

Back

mechanical energy

Front

True or False: Negative work means that energy is being removed from the object.

Back

True

Front

Work involves a force acting upon a ________ object, either with its motion or against its motion.

Back

moving object

Front

What is the definition of Mechanical Energy?

Back

the ability to do work

Front

In which of the following situations is kinetic energy decreasing? A baseball is headed upward after being thrown up in the air.

Back

Kinetic energy is decreasing when the baseball is thrown upward.

Front

What is Kinetic Energy?

Back

The energy an object has because of its motion.

Front

What is Potential Energy?

Back

The energy stored in an object due to its position or configuration.

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 formula for calculating Potential Energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What does the Work-Energy Principle state?

Back

The work done on an object is equal to the change in its kinetic energy.
