Brainpop: Potential Energy

  1. What is potential energy?
  2. The energy an object has due to its position or condition
  3. The energy an object has due to its motion
  4. The energy an object has due to its chemical composition
  5. The energy an object has due to it atomic structure
  1. Which object has to most potential energy?
  2. A ball resting on the ground
  3. A ball being thrown at 100 miles per hour
  4. A ball on top of a refrigerator
  5. A ball resting on the edge of a cliff
  1. When does a yo-yo have the most potential energy?
  2. When it’s at its highest point
  3. When it’s at its lowest point
  4. When it’s moving between its highest and lowest points
  5. When it’s moving at its top speed
  1. Which is a synonym for potential energy?
  2. Stored energy
  3. Energy of motion
  4. Energy due to gravity
  5. Mechanical energy
  1. Why do objects at high elevations have more potential energy than objects at low elevations?
  2. Because the thinner air at higher elevations means objects have a greater potential to move very fast
  3. Because objects at high elevations are closer to the sun, which is the source of all energy on earth
  4. Because objects at high elevations tend to move slower than objects a low elevations
  5. Because gravity gives objects at high elevations that potential to fall much further
