forces and elasticity

Question 1

explain the relationship between the force applied and the extension of an elastic object.

Answer 1

the extension is directly proportional to the force applied, provided that the limit of proportionality is not exceeded

Question 2

what is meant by an inelastic deformation

Answer 2

• a deformation which results in the object being permanently stretched
• the object doesn’t return to its original shape when the force is removed

Question 3

what type of energy is stored in a spring when its stretched?

Answer 3

Elastic potential energy

Question 4

what can extension be replaced within the equation for spring force?

Answer 4

compression
