Potential and Kinetic Energy

Front

What is the definition of 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 the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, commonly associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Where is kinetic energy maximum on a roller coaster?

Back

At the bottom of a big hill.

Front

What type of energy does a flashlight have when it is turned off?

Back

Potential energy.

Front

Which passenger on a roller coaster has the most potential energy?

Back

The passenger at the highest point.

Front

If two vehicles are moving at the same speed, how does their size affect their kinetic energy?

Back

The vehicle with greater mass will have greater kinetic energy, as KE is directly proportional to mass.

Front

What type of energy is represented by a stretched rubber band?

Back

Potential energy.

Front

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has due to gravitational force.

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 potential energy and kinetic energy in a closed system?

Back

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