1.
The unit of the spring constant is
N
m/N
N/m
N m
2.
A spring extends by 5.0 cm under a force of 10 N. Its spring constant is
200 N/m
0.50 N/m
2.0 N/m
50 N/m
3.
A spring of k = 40 N/m is extended by 0.25 m. The force is
160 N
10 N
0.0063 N
1.0 N
4.
The gradient of a straight force-extension graph gives
the energy stored
the original length
the weight
the spring constant
5.
When the force on a spring is doubled (within the limit), the extension
halves
stays the same
doubles
quadruples
6.
A graph of force against extension bends away from a straight line at 8.0 N. This point is the
limit of proportionality
original length
spring constant
