Front

What is stored energy?

Back

Stored energy, also known as potential energy, is the energy that an object has due to its position or condition. For example, a marble at the top of a ramp has stored energy because of its height.

Front

When is the stored energy of a marble the greatest?

Back

The stored energy of a marble is greatest when it is resting at the top of the ramp.

Front

What is potential energy?

Back

Potential energy is the energy that an object possesses because of its position or condition. The higher an object is, the more potential energy it has.

Front

Which paper airplane has the most potential energy?

Back

A paper airplane flying 50 feet above the ground has the most potential energy.

Front

How does weight affect potential energy?

Back

The potential energy of an object increases with its weight. A heavier object, like a 100-pound rock, has more potential energy than a lighter object.

Front

What role does the stomach play in energy storage?

Back

The stomach stores food for energy, breaking it down into nutrients that the body can use.

Front

What should scientists do to confirm their experiment results?

Back

Scientists should compare their results with another scientist who is conducting the same experiment to confirm accuracy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does height affect potential energy?

Back

The higher an object is above the ground, the more potential energy it has due to gravity.

Front

What is the formula for potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
