Potential and Kinetic Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. It is often associated with gravitational potential energy, which depends on an object's height and weight.

Front

At which point is kinetic energy greatest in a falling object?

Back

Kinetic energy is greatest just before the object hits the ground, as it has converted most of its potential energy into kinetic energy.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height of the object above a reference point and the weight (mass) of the object.

Front

What is the formula for gravitational 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 type of energy is associated with a moving car?

Back

A moving car possesses kinetic energy due to its motion.

Front

What type of energy is stored in a compressed spring?

Back

A compressed spring stores elastic potential energy.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is associated with electromagnetic radiation.

Front

What type of energy does a pile of coal represent?

Back

A pile of coal represents potential energy, as it has the potential to be burned for fuel.

Front

What kind of energy is present in a rock at the edge of a cliff?

Back

A rock at the edge of a cliff has gravitational potential energy due to its height above the ground.
