23/24 Energy and Engineering CBA Practice

Front

What is the purpose of a spring scale?

Back

A spring scale is used to measure the force exerted on an object, typically in units of weight (newtons or pounds).

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor, which can be converted into other forms of energy, such as light or thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

How does energy transfer from the sun to the earth?

Back

Energy from the sun is transferred to the earth primarily through radiation, which is the transfer of energy through electromagnetic waves.

Front

What is the function of mirrors in a periscope?

Back

Mirrors in a periscope are positioned to reflect light from the surface, allowing a person to see above the water while remaining submerged.

Front

What happens to your shadow when you walk into the shade?

Back

When you walk into the shade, you are no longer blocking the sunlight, which means your shadow is not cast in that area.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is responsible for the sense of sight.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when electrical energy is converted into light energy in a light bulb.

Front

What is the role of thermal energy in weather?

Back

Thermal energy plays a crucial role in weather patterns, influencing temperature, wind, and precipitation.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of motion.
