- Elasticity
- WORK DONE to an elastic object = stored as ELASTIC POTENTIAL ENERGY
- Apply force & it may stretch & change shape
- An object that can revert to its ORIGINAL shape = elastic
- Elastic potential energy = converted to Kinetic energy when force is REMOVED
- Object returns to original shape
- Extension = directly proportional to FORCE
- F = k X e
- F = force (N)
- k = spring constant (N/m)
- e = extension (m)
- Stops working if force is big enough
- Small forces, force & extension = proportional (straight-line)
- Is a MAXIMUM force object can take = LIMIT OF PROPORTION- ALITY
- If force increases past this point, material = PERMANENTLY STRETCHED
- Is a MAXIMUM force object can take = LIMIT OF PROPORTION- ALITY
- F = k X e
- WORK DONE to an elastic object = stored as ELASTIC POTENTIAL ENERGY
