IQWST PS 1-5 Test Review

Front

What is stored energy?

Back

Potential energy is stored energy.

Front

In an experiment, what is the independent variable?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable. In Ms. S's experiment, it is the mass of the ball.

Front

What is energy conversion?

Back

Energy conversion is the process of changing one form of energy into another form of energy.

Front

At which point is potential energy greatest in a ramp experiment?

Back

Potential energy is greatest at the highest point of the ramp.

Front

What kind of energy is in a stretched rubber band?

Back

A stretched rubber band contains potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with the mass of the object and the square of its velocity.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

Front

How does height affect potential energy?

Back

Potential energy increases as the height of an object increases.
