Thermal properties refer to
How a material heats up
How a material responds to the cold
how materials heat up and cool down
how a material responds to a change in temperature
What property does a brake disc need to have
elasticity
hardness
flexibility
Ductility
Ductility describes
a materials ability to be drawn into a wire or rolled into a sheet
a materials ability to stretch
A material that can be reshaped
A material that can be rolled into a sheet of thin metalic material
Hardness is a measure of
how hard a material is
how well a material can withstand dents and scratches
how a material can withstand friction
toughness
a material which has high tensile strength will
be able to withstand a large amount of force under tension
not be able to withstand a large amount of force under tension
be strong all the time
be tough and resist all impacts
What is an elastic material?
Change their shape when under a load, but return to their original shape when the load is removed.
Change their shape when under a load, but they remain permanently deformed when the load is removed.
Break or crumble rather than deform under a load.
Can easily be shaped by hammering or rolling, and they keep their new shape. Some materials can be made more malleable by heating.

Why is plywood the most suitable material for a skateboard?
The grain runs in two directions
It can resist forces in different directions
It can be easily shaped by lamination
Physical properties are the traits a material has...
before it is used
when it is manipulated
Working properties are how a material behaves...
before it is used
when it is manipulated.
