Q
Describe a method to investigate the link between force and extension
A
- Set up as shown and measure length of spring with a range of masses e.g. 0, 4, 6, 8 N. (Measuring the natural length of spring before hand).
- For each weight record the length of the spring.
- Calculate the extension of a given weight by subtracting its length from the starting length of the spring.
- Repeat.
- Inaccuracy comes from parallax errors, not fixing the ruler, not allowing spring to stop oscillating. Not taking readings from eye level.
