Kinetic and Potential Energy

Front

What is Kinetic Energy (KE)?

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 (PE)?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a rock at the edge of a cliff has gravitational potential energy.

Front

How does velocity affect Kinetic Energy?

Back

As the velocity of an object increases, its Kinetic Energy increases. This is because KE is proportional to the square of the velocity.

Front

What happens to Kinetic Energy when an object's speed decreases?

Back

The Kinetic Energy of the object decreases as its speed decreases.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy increases as the mass of an object increases, assuming the velocity remains constant.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has Potential Energy due to its position and the force applied to compress it.

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 formula for calculating Potential Energy?

Back

Potential Energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy does a moving car have?

Back

A moving car has Kinetic Energy due to its motion.

Front

If two objects have the same mass, but one is moving faster, which has more Kinetic Energy?

Back

The object that is moving faster has more Kinetic Energy because KE depends on the square of the velocity.
