Work, Power, and Energy Worksheet

Work, Power, and Energy

Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.

1. Which of the following is the correct unit for work?

2. Power is defined as:

1. The law of conservation of energy states that energy cannot be created or  .

2. When a force acts on an object and causes displacement,   is done.

3. Potential energy is the energy an object possesses due to its   or state.

1. A box is pushed with a force of 50 N across a distance of 10 meters. Calculate the work done.

2. A motor performs 1200 J of work in 6 seconds. What is the power output of the motor?

1. If you hold a heavy object stationary, you are doing work on it.

2. Kinetic energy is directly proportional to the square of an object's velocity.

1. Explain the work-energy theorem and provide a real-world example of its application.

2. Describe the energy transformations that occur when a ball is thrown vertically upwards and then falls back down.
