1.
The extension of a spring is
its stretched length
its original length
its length times the force
stretched length minus original length
2.
A spring of original length 12 cm is 15.5 cm long when loaded. The extension is
12 cm
3.5 cm
15.5 cm
27.5 cm
3.
The straight-line part of a force-extension graph shows that
the spring has broken
extension is constant
extension is directly proportional to force
force is constant
4.
A mass of 0.20 kg hangs from a spring. The force is about
2.0 N
0.02 N
0.20 N
20 N
5.
A spring that does not return to its original length after unloading has been stretched past
its original length
its elastic limit
zero extension
its mass
6.
To reduce parallax error in reading the rule, you should
look from above
use a shorter rule
read the rule from the side
place the rule close to the spring and read at eye level
