Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

How is electrical energy generated from mechanical energy in a wind turbine?

Back

In a wind turbine, mechanical energy from the wind turns the blades, which spins a generator to convert that mechanical energy into electrical energy.

Front

What causes the seasons on Earth?

Back

The tilt of Earth's axis as it orbits the sun causes different parts of Earth to receive varying amounts of sunlight throughout the year, resulting in the seasons.

Front

What is a spring tide?

Back

A spring tide occurs when the Earth, moon, and sun are aligned, resulting in higher high tides and lower low tides.

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 at the top of a hill has gravitational potential energy.

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

What happens to a tennis ball's energy as it falls?

Back

As the tennis ball falls, its potential energy decreases while its kinetic energy increases until it reaches the ground.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released during a chemical reaction.

Front

What energy changes occur when a match is struck?

Back

When a match is struck, the chemical energy stored in the match is converted into thermal energy (heat) and light energy (flame).

Front

What is the role of the sun in Earth's climate?

Back

The sun provides the energy that drives weather patterns and climate on Earth, influencing temperature, precipitation, and wind.
