Hooke’s Law

Next steps

• Complete your graph from last lesson. Don’t plot any more than 10 - 15 points.

• Work out the gradient for the line.

• Work out the size of the error bars for each plot.

• Determine the elastic limit

Gradient for you graphs

Working out uncertainty

Working out uncertainty 2

• Whether you are multiplying or dividing units, you will always add the uncertainties together.

• I measure the side of a cube to be 10±0.5cm

• What is its volume if all dimensions are the same?

• What is the uncertainty with that volume?
