Kinetic and Potential Energy Grom

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

What type of energy is involved when a roller coaster is at the top of a hill?

Back

At the top of a hill, a roller coaster has maximum potential energy and minimum kinetic energy.

Front

How does energy transfer occur in a pendulum?

Back

In a pendulum, energy transfers between potential energy at the highest point and kinetic energy at the lowest point.

Front

What is the role of friction in energy transformation?

Back

Friction converts kinetic energy into thermal energy, often resulting in energy loss in mechanical systems.

Front

What is an example of chemical energy?

Back

Food contains chemical energy, which is released when the body metabolizes it.

Front

How is energy from the Sun transferred to Earth?

Back

Energy from the Sun is transferred to Earth through radiation.
