Elastic potential energy
Elastic potential energy
A force acting on an object may cause the shape of an object to change. Elastic objects can store elastic potential energy if they are stretched. For example, this happens when a catapult is used.Â
TAsk 1 - Get to know the equation
TAsk 1 - Get to know the equation
Below is the equation for calculating the amount of energy stored in a squashed or stretched object.
Complete task 1 on your companion sheet by labeling the equation.
E = The amount of energy Joules (J)
1/2 = the number 0.5
k = The spring constant in Newtons per Metre (N/m)
e = extension of the spring in metres (m)
Task 2 - extension?
Task 2 - extension?
Before we can do a calculation we need to understand what is meant by extension.
Put simply, it is how much longer the spring is compared to it original size.
Not the total length of the spring after it has been stretched
Complete task 2 on the companion sheet by calculating the extension of each spring.

Mini Practical
To understand full what a spring constant is, we need to do a bit of a practical.
Read the pratical worksheet on the right and then use the equipment provided to run the experiment

Remember!
Energy transferred is called WORK DONE
