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 energy stored in an object due to its position or state, such as a ball held at a height.

Front

What is kinetic energy?

Back

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

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 transfer in a bouncing ball?

Back

In a bouncing ball, energy transfers from potential energy at the highest point to kinetic energy as it falls, and back to potential energy as it rises.

Front

What is an example of energy transformation in a pendulum?

Back

In a pendulum, energy transforms from potential energy at the highest point to kinetic energy at the lowest point.

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 hills and transforms into kinetic energy as the coaster descends.

Front

What happens to the total energy in a closed system?

Back

In a closed system, the total energy remains constant, even as it transforms between potential and kinetic energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as mass times gravity times height.
