Required Practicals

Question 1

What is the method for the spring required practical?

Answer 1

• put spring on clamp stand
• add 100g mass to the spring
• measure the extension of the spring (using the ruler) and record the result
• repeat adding an extra 100g mass each time, ensuring not to go above 600g total to not inelastically deform the spring

Question 2

What is a potential mistake for the spring practical?

Answer 2

Adding too many masses can stretch the spring too far, meaning that any future readings would be inaccurate.

Question 3

What is the independent variable of the spring practical?

Answer 3

The force on the spring

Question 4

What is the dependent variable of the spring practical?

Answer 4

The extension of the spring

Question 5

What are the control variables of the spring practical?

Answer 5

The spring constant of the spring used, the type of spring, the units measured in.

Question 6

What is a hazard of the spring practical?

Answer 6

The masses falling onto the person’s feet.
To minimise the risk, the number of masses used should be kept to a minimum but enough to produce a good range of results.
