PS2: Unit Review - Lessons 1-6

Front

Where is the potential (gravitational) energy the greatest?

Back

Potential (gravitational) energy is greatest at the highest point in a gravitational field.

Front

What is the dependent variable in an experiment to train a dog?

Back

The dependent variable is the amount of time the dog follows commands.

Front

What two factors determine the amount of kinetic energy an object has?

Back

Kinetic energy depends on mass and speed.

Front

What is a controlled variable in a scientific experiment?

Back

A controlled variable is a variable that is not changed and remains constant.

Front

What is energy in motion called?

Back

Energy in motion is known as kinetic energy.

Front

Define potential energy.

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is speed.

Front

What is an independent variable?

Back

An independent variable is the variable that is changed or controlled in an experiment.

Front

What is the relationship between mass and gravitational potential energy?

Back

Gravitational potential energy increases with an increase in mass.

Front

What is the difference between kinetic and potential energy?

Back

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