Harnessing Human Energy Chapter 1 Flashcard

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a battery stores potential energy that can be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, when a wind-up toy is released, it moves and has kinetic energy.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It is what makes things move or change.

Front

What is evidence in scientific terms?

Back

Evidence is information about the natural world that is used to support or go against a claim.

Front

What is an example of potential energy?

Back

A drawn bow has potential energy because it is in a position to do work when released.

Front

What is an example of kinetic energy?

Back

A rolling ball has kinetic energy because it is in motion.

Front

How does energy relate to movement?

Back

Whenever something moves or changes, it is because of energy.

Front

What happens to potential energy when an object is in motion?

Back

Potential energy can be converted into kinetic energy when an object starts to move.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be transformed into kinetic energy and vice versa, depending on the object's state.

Front

What is an example of energy transformation?

Back

When a car accelerates, chemical energy from fuel is transformed into kinetic energy.
