- Forces that change shapes
- Forces can deform or change shape. (foam in a cushion changes easily)
- Change in shape can be undetectable - its either a tiny change or it occurs to quickly to notice (this is when the object returns to original shape)
- Elastic objects are shaped by push ad pull - but will return
- Work done = when an object is pushed/pulled
- Potential energy = energy stored in object
- Extension = the added length when a spring srtretches
- Proportional = If a force on the spring doubles as the amount it stretches does too
- F = k (x)
- F = force (n)
- K = spring constant (N/m)
- X = extension (m)
- Spring constsant is worked out from shape of graph
- Rearrange equation to get subject you want!
