1)
a) What are the 3 different ways that an elastic object can be deformed?
b) When a force deforms an elastic object, energy is transferred to which energy store in the elastic object?
2)
a) Define an elastic deformation.
b) Define an inelastic deformation.
3) The graph below shows how the extension of a spring changes as we increase the force (weight) acting on a spring.

a) Describe the relationship between force and extension prior to point P. Explain your answer.
b)
i) What is the name of point P?
ii) What does point P mean?
c) I have added another point on the graph called point E, which is the elastic limit.

What does the elastic limit mean?
4) Write down the equation that links force, extension and spring constant. Give the units for the values as well.
5) This question is all about spring constants.
a) If we have a spring that requires a large force to either extend or compress, would the spring have a low or high value for spring constant (k)?
b) If we have a spring that requires a small force to either extend or compress, would the spring have a low or high value for spring constant (k)?
6) Find the force applied to a spring with a spring constant of 30 N/m when it extends by 6 cm.
7) A spring has a spring constant of 80 N/m. When a force is applied to the spring, it extends by 12 cm. Find the force applied to the spring.
8) A spring has a spring constant of 50 N/m. I apply a force of 3.5 newtons to the spring, which results in the spring extending. Find the length of the extension caused by this 3.5 N force. Give your answer in centimetres (cm).
9) A 6 newton force causes a spring to compress by 8 centimetres. Work out the spring constant for the spring.
