Potential and Kinetic energy

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 its velocity.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object is in motion, such as a ball falling from a height.

Front

What force opposes the motion of a falling object?

Back

Air resistance opposes the motion of a falling object, slowing it down.

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 PE = mass (m) * gravity (g) * height (h).

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 role of friction in energy transfer?

Back

Friction converts kinetic energy into thermal energy, slowing down moving objects.

Front

When is an object at its maximum potential energy?

Back

An object is at its maximum potential energy when it is at its highest point.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.
