Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as 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 happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

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

How does energy flow when a fruit falls from a tree?

Back

The energy flows from potential energy (when the fruit is on the tree) to kinetic energy (as it falls) and may produce sound upon impact.

Front

What happens to the energy of a toy car going up a ramp?

Back

As the toy car goes up the ramp, its potential energy increases while its kinetic energy decreases.

Front

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

Back

In a pendulum, potential energy is highest at the highest points, while kinetic energy is highest at the lowest point.

Front

What is an example of energy transformation in everyday life?

Back

An example is a roller coaster: as it climbs, it gains potential energy, and as it descends, that energy transforms into kinetic energy.

Front

What happens to energy when a ball is dropped?

Back

When a ball is dropped, its potential energy decreases and transforms into kinetic energy as it falls.
