Stored Energy
Energy that waits, then moves.
What your child practises
Practises the idea that objects can hold stored energy (chemical, elastic, height) and that it can be transferred to cause events such as motion, heat and light.
Manitoba Curriculum learning outcome: SCI.6.E.4, SCI.6.E.5 · stored energy in objects, and how it is transferred to cause events
Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
A rock at the top of a cliff has…
- no energy
- only moving energy
- stored energy because of its height
Show answer
stored energy because of its height
Hint: The higher it is, the more energy is stored.
Question 2
Which of these is a source of stored energy for a car?
- a seatbelt
- a flat tire
- gasoline
Show answer
gasoline
Hint: Gasoline stores chemical energy.
Question 3
A bouncing ball goes lower each bounce. Some energy has become…
- new energy
- stored forever
- heat and sound
Show answer
heat and sound
Hint: A bit of energy escapes each bounce.
Question 4
A ball at the top of a hill starts rolling. Stored energy is changing to…
- chemical energy
- magnetic energy
- motion energy
Show answer
motion energy
Hint: It speeds up as it goes down.
Question 5
Energy cannot be…
- created or destroyed
- stored
- transferred
Show answer
created or destroyed
Hint: It changes form and moves.
Question 6
A hydroelectric dam uses water stored high up. This works because the water has…
- stored energy that becomes motion energy when it falls
- only heat
- no energy
Show answer
stored energy that becomes motion energy when it falls
Hint: Falling water turns turbines.
