Kinetic and Potential energy Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as 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, commonly associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Where is kinetic energy maximum on a roller coaster?

Back

At the bottom of a big hill.

Where is potential energy maximum on a roller coaster?

Back

At the top of a big hill.

Front

How does the speed of an object affect its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

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 relationship between kinetic and potential energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, demonstrating the principle of conservation of energy.

Front

What type of energy is stored in a stretched rubber band?

Back

Potential energy.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy is affected by the object's mass, the height above the ground, and the acceleration due to gravity.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.
