Forces and elasticity Flashcards
1
Q
How many forces are required to bend, stretch or compress an object?
A
More than one
2
Q
Elastic distortion
A
A change in shape where the object will return to its original shape if the forces are removed.
3
Q
Inelastic distortion
A
A change in shape where the object will not return to its original shape.
4
Q
Elastic limit
A
The furthest an object can be stretched and still return to its original shape
5
Q
Hookes law
A
If a force applied to stretch a string is doubled, then the extension of the spring will also double
6
Q
Equation for Hooke’s law
A
force exerted of spring (N) = spring constant (N/m) x extension (m)
F=ke
