1. Prefix units 2. Uncertainties Adding or subtracting- Add the absolute uncertainties Multiplying or dividing- Add the percentage uncertainties Raising to a power- Multiply the percentage uncertainties by the power 3. Percentage un- certainty in the gradient uncertainty = ½(line of best fit - line of worst fit) Percentage uncertainty = uncertainty ÷ gradient of best fit line (× 100) 4. Speed Rate of change of distance 5. Displacement The distance an object has t...
