Potential and Kinetic Energy Answers

Which two factors are used to calculate the kinetic energy of an object?

Ella has a mass of 56 kg, and Tyrone has a mass of 68 kg. Ella is standing at the top of a skateboard ramp that is 1.5 meters tall. Which conclusion is best supported by the given information?

Let's consider a scenario of a roller coaster ride. As the roller coaster at the top begins to descend, it loses height, which means its potential energy decreases and kinetic energy starts increasing and reaches its maximum value.By using the above scenario, which statement best compares potential and kinetic energy?
