KInetic and Potential Energy Modified

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

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy. This is because potential energy is directly proportional to height.

Front

What happens to kinetic energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

At which point does a roller coaster have the greatest potential energy?

Back

A roller coaster has the greatest potential energy at the highest point of the track.

Front

At which point does a roller coaster have the greatest kinetic energy?

Back

A roller coaster has the greatest kinetic energy at the lowest point of the track.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is proportional to the square of the velocity. This means that if the velocity doubles, the kinetic energy increases by a factor of four.

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 using the formula PE = mgh.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass. If the mass of an object doubles, its kinetic energy also doubles, assuming the velocity remains constant.
