Energy Transfer & Transformations (PMA #3 CS3 2223)

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, often resulting in a change in energy form.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting potential energy to kinetic energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a ball at the top of a hill.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, keeping the total energy constant.

Front

How does a solar panel work?

Back

A solar panel transforms electromagnetic (light) energy from the Sun into electrical energy.

Front

What is an example of energy transformation in a light bulb?

Back

In a light bulb, electrical energy is transformed into thermal energy (heat) and light energy.

Front

What is the relationship between potential and kinetic energy in a roller coaster?

Back

In a roller coaster, potential energy is highest at the top of the track, and kinetic energy is highest at the bottom.

Front

What is an example of energy being conserved in a closed system?

Back

In a closed system, such as a pendulum, the total energy remains constant as it swings back and forth, converting between potential and kinetic energy.
