2i Force and Motion IX

The photo shows an image of a copper spring. A student found that he need to do 15J of work to stretch the spring to an extension of 5cm. What is the spring constant of the spring?

Which of the followings are the factors that affect the spring constant of a spring?

The figure above shows 3 springs of different diameter and length. Arrange the springs in
according to their spring constant in ascending order.

A load of mass 0.5kg is hung at the end of a spring. Given that the extension of the spring is 30cm. Find the work done by the weight to stretch the spring.

The figure above shows 2 identical springs, one without load and one with a load of mass, m.
Find the potential energy stored in the spring with load if the spring constant is 500Nm^-1.

The graph shows the force exerts on a spring against the extension of the spring. What is the spring constant of the spring?

The graph shows how the extension of a spring varies when different forces exerted on the
spring. What is the elastic limit of the spring?

The diagram above shows 2 identical spring, one without load and one with a 10N load. What will be the length of the spring to the left when a load of 25N is hung on it?

The graph shows the force applied to 2 springs against the extension of the spring. Between the 2 springs, which one is stiffer?

The diagram above shows the length of a spring when it is load free and when a load of
10N hung on it. Find the spring constant of the spring.
