An elastic object such as a spring stores __________ when stretched or squashed
Elastic potential energy
1 of 12
The extension of an elastic object is _____________ to the force applied
Directly proportional
2 of 12
_____________ on an elastic object when its shape changes
Work is done
3 of 12
When an elastic object - such as a spring - is stretched, the increased length is called its...
Extension
4 of 12
The extension of an elastic object is _____________ to the force applied to it
Directly proportional
5 of 12
F = k × e F=?
F = Force (Newtons)
6 of 12
F = k × e k=?
k = spring constant (N/m)
7 of 12
F = k × e e=?
e = extension (m)
8 of 12
When will this equation not work?
If the elastic limit (limit of proportionality) is exceeded
9 of 12
What will happen if a spring is stretched too much?
It will not return to its original shape once the load is removed
10 of 12
How do you find the spring constant?
Work out the gradient
11 of 12
How do you find the extension?
The new length minus the original length
