A rock with a mass of 5 kg is perched on a ledge that is 10 meters high. What is the potential energy of the rock?
What equation would you use to solve this problem?
PE = m * g * h
KE = 0.5 * m * v²
PE = 5 * 9.8 * 10
KE = 0.5 * 5 * 10 * 10
A car with a mass of 1200 kg is traveling at a speed of 20 m/s. Calculate the kinetic energy of the car.
What equation would you use to solve this problem?
PE = m * g * h
KE = 0.5 * m * v²
PE = 5 * 9.8 * 10
KE = 0.5 * 5 * 10 * 10

The Law of Conservation of Energy says that:
Energy can be created, but once it is used it disappears forever
Energy cannot be created or destroyed
Energy can't be created but can be destroyed
Energy can be created and destroyed
What is one of the main benefits of renewable energy?
Once you use the energy source, you can't get it back
The energy source can either be regrown, or it won't run out
It puts harmful poisins in the atmosphere
It reduces the number of greenhouse gases in the atmosphere
