• elastic
• non-metals only

Hooke's Law fails when a material reaches its:

• elastic limit
• end of tether
• fracture stress

If extension = Stretched length - original length. What is the extension of spring D.

• 1mm
• 2mm
• 3mm
• 0mm

Spring constant is measured in

• N

• N/m

• m

Which of the following statements about elastic spring force is false?

• Elastic spring force is exerted by a spring when the spring is stretched or compressed.

• When a force is applied on a spring, the spring extends or becomes longer.

• Elastic spring force allows a stretched spring to return to its original strength even if the spring is stretched beyond the limit.

The mathematical relationship between Force on a Spring and Elastic Potential Energy is

• direct proportionality

• inverse proportionality

• an exponential
