A pupil puts different forces on a spring. Starting with the smallest extension, sort the forces into order of the extension they cause.
The figure shows a spring before and after a weight has been added. What is the extension of the spring when the mass is placed on it?
The photograph shows a pupil measuring the extension of a spring. How could the pupil improve the accuracy of the measurement?
The gravitational field strength on Earth is 10 N/kg. What size mass will have a weight of 1 N?

Which statement about springs is correct when they are stretched?
What happens to the extension of a spring if the force acting on it is increased from 6 N to 18 N?
Which of the following describes the line of best fit for a graph where the two variables are directly proportional?
Some pupils add too much force to a spring. For each extra 1 N they then add, the extension increases much more than expected. What will happen to the spring when the force is removed.
