Spring toys were primed and then the height they jumped up into the air was noted. The Elastic Potential energy was converted into first Kinetic and then Gravitational Potential energy.
Which is the spring toy and which the bouncy student?
They used the iPads to record the highest point of the flight.
The App was slopro so they could scrub through the action to find the highest point.
Here is a primed toy ready to spring.
We also need to know the mass so the force can be calculated
Then complicated calculations need a computer
The force x the distance (N x m) gives us the energy in Joules
All tests were conducted in a fair, accurate and reliable manner.
And lots of toys were tested so a good comparison could be made
Most of the spring toys actually appear as a blur on these photos
Sometimes jumping toys come as a bit of a shock, even when you were expecting them!
