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?
10 of 12
