Kinetic and Potential Energy

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 * m * v^2

Front

A ball with a mass of 0.5 kg is thrown with a velocity of 10 m/s. What is its kinetic energy?

Back

25 J

Front

What is the formula for calculating potential energy?

Back

Potential energy = mass * gravity * height

Front

What is the SI unit of potential energy?

Back

Joule

Front

A car with a mass of 1000 kg is traveling at a speed of 20 m/s. What is its kinetic energy?

Back

200,000 J

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on the mass of the object and the square of its velocity.

Front

What factors affect potential energy?

Back

Potential energy depends on the mass of the object, the height above the ground, and the acceleration due to gravity.

Front

What is the relationship between kinetic and potential energy in a roller coaster?

Back

As a roller coaster ascends, kinetic energy is converted to potential energy; as it descends, potential energy is converted back to kinetic energy.
