Brainpop: Potential Energy
- What is potential energy?
- The energy an object has due to its position or condition
- The energy an object has due to its motion
- The energy an object has due to its chemical composition
- The energy an object has due to it atomic structure
- Which object has to most potential energy?
- A ball resting on the ground
- A ball being thrown at 100 miles per hour
- A ball on top of a refrigerator
- A ball resting on the edge of a cliff
- When does a yo-yo have the most potential energy?
- When it’s at its highest point
- When it’s at its lowest point
- When it’s moving between its highest and lowest points
- When it’s moving at its top speed
- Which is a synonym for potential energy?
- Stored energy
- Energy of motion
- Energy due to gravity
- Mechanical energy
- Why do objects at high elevations have more potential energy than objects at low elevations?
- Because the thinner air at higher elevations means objects have a greater potential to move very fast
- Because objects at high elevations are closer to the sun, which is the source of all energy on earth
- Because objects at high elevations tend to move slower than objects a low elevations
- Because gravity gives objects at high elevations that potential to fall much further
Brianpop: Kinetic Energy
- Kinetic and potential energy are the two types of energy that relate to:
- Change
- Friction
- Density
- Motion
- What is kinetic energy?
- The stored energy of an object due to its position or condition
- The energy that an object has due to its motion
- The energy an object has due to its existence
- The energy an object has due to its volume
- The amount of kinetic energy an object has depends on its:
- Mass and volume
- Volume and friction
- Mass and speed
- Speed and density
- Which of the following has the most kinetic energy?
- A car traveling at 80 kph
- A tractor traveling at 80 kph
- A cheetah running at 80 kph
- A motorcycle traveling at 80 kph
- When is energy transferred from object to object?
- When those objects pass one another
- When the first object outweighs the second object
- When the first object has more potential energy than the second object
- When those object collide
