what is mass
is the meassure of the amount of material an object is made of
can mass change
no
what is weight
the force exerted on a body by gravity
what hapends to the force if the distance is bigger
the smaller the force
what is elsatic demormation
when material goes back to its orignal form
what is plastic demormation
a process in wich the object due to applied force changes its sieze or shape in a way that is not reversible
what is elastic limit
the maximum extent to which a solid may be streched without perment alteration
what does hookes law state
if you apply force to a spring the force streches the spring
