What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has potential energy.

Front

What is the natural world?

Back

The natural world refers to all living and non-living things that occur naturally, including plants, animals, rocks, and weather.

Front

What do physical scientists study?

Back

Physical scientists study the physical world, including matter, energy, and the laws that govern them.

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 an object's position.

Front

Can an object have both kinetic and potential energy?

Back

Yes, an object can have both types of energy. For example, a roller coaster at the top of a hill has potential energy, and as it descends, that energy converts to kinetic energy.

Front

What is an example of energy in everyday life?

Back

Examples include a moving car (kinetic energy), a stretched rubber band (potential energy), and sunlight (radiant energy).

Front

What is the role of energy in physical science?

Back

Energy is a fundamental concept in physical science, as it helps explain how and why things move and change.

Front

What is a physical system?

Back

A physical system is a collection of physical entities that interact with each other, such as a car engine or a weather system.
