Question 1

force and extension required practical

Answer 1

Attach the two clamps to the stand using the bosses. Th top clamp should be further out than the shorter one

Place the clamp near the edge of a bench so that the ends of the clamps stick out beyond the bench

Place a heavy weight on the base of the clamp stand to stop the clamp stand from tipping over

Hang the spring from the top clamp and hang a ruler from the bottom clamp

Take a reading of the spring, this is the length of the unstretched spring

Carefully hook the base of the weight stack, this weighs 1N, then take a reading on the ruler and record it on a table

Add further weights, ensuring to take measurements every time a weight is added, ensure to record the weight and length of the spring in a table

Add a third column called ‘extension’ and calculate he extension every time a weight was added to the spring

Plot a graph of extension against weight
