Energy And Movement Flashcards
What is stored energy?
The energy in a compressed spring
What does compress mean
Squeeze or push the parts together
What is elastic
A material that quickly returns th its original shape after it has been stretched
How does a battery in a torch work
When the switch is on the store of energy (the chemicals ) produce energy which makes the bulb shine
How do you give an elastic band energy
When you stretch or twist and elastic band you are unloading it with stored energy this store of energy can be used to make something work to give the elastic more energy stretch or twist it more
How is a handheld catapults and elastic powered aeroplane a good example of how stored energy is used
to load the catapults with stored energy you have to pull the rubber strips back.When an elastic band has been loaded with stored energy and the elastic is released the stored energy turns to movement energy
how can we store energy in elastic
By stretching or twisting it
How can we store energy in the spring
I can compress it
