Potential and Kinetic Energy Worksheet

Potential and Kinetic Energy

Read each question carefully and answer to the best of your ability. Show your work for any calculations.

1. What type of energy is stored in an object due to its position or state?

2. An object with a mass of 10 kg is lifted to a height of 5 meters. If the acceleration due to gravity is 9.8 m/s², what is its gravitational potential energy?

1. The energy of motion is called   energy.

2. A stretched rubber band has   potential energy.

3. The law of conservation of energy states that energy cannot be created or  , but can only change forms.

1. As a roller coaster car goes down a hill, its kinetic energy is converted into potential energy.

2. A heavier object will always have more kinetic energy than a lighter object, regardless of speed.

1. Describe the difference between potential energy and kinetic energy, providing an example for each.

2. A car is traveling at 20 m/s and has a kinetic energy of 200,000 J. What is the mass of the car? (Formula: KE = 0.5 * m * v²)

Analyze the energy pyramid below and answer the question.

3. In the context of the energy pyramid, explain how energy transformations relate to potential and kinetic energy as energy moves through different trophic levels.
