12.10 Energy transformations

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or height.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion.

Front

What is the formula for calculating Kinetic Energy?

Back

Front

What type of energy transformation occurs in a hydroelectric power plant?

Back

In a hydroelectric power plant, the energy transformation primarily occurs from Potential Energy to Kinetic Energy to Electrical Energy.

Front

What is the relationship between Potential Energy and height?

Back

Potential Energy increases with height; the higher an object is, the more Potential Energy it has.

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of Potential Energy and Kinetic Energy in an object.

Front

How does friction affect energy transformations?

Back

Friction converts some mechanical energy into thermal energy, reducing the efficiency of energy transformations.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of Chemical Energy?

Back

Chemical Energy is stored in the bonds of chemical compounds, such as in food or batteries.

Front

What happens to Kinetic Energy as an object slows down?

Back

As an object slows down, its Kinetic Energy decreases.
