Key Stage 1
Meaning
Some solids can change shape when you squash, twist or try to stretch them. This is called deformation.
About Deformation
- If a solid is stretchy, or bendy its shape can be changed.
Materials that can be deformed:
Materials that cannot be deformed:
Key Stage 3
Meaning
Deformation is to change the shape of an object by applying a pair of forces.
About Deformation
- Objects are deformed by the action of a pair of Equilibrium Forces.
- These equilibrium forces are equal in magnitude but opposite in direction acting at different ends of an object to deform it. If there is only one force then the object will not deform it will just accelerate.
- Some objects deform plastically which means they stay in their new shape after the forces are gone.
- Some objects deform elastically which means they will return to their original shape when the forces are gone.
