I can use newton meters to measure forces accurately.
Measuring forces
I can use newton meters to measure forces accurately.
Lesson details
Key learning points
- Forces are measured with a newton meter.
- Forces are measure in newtons (N).
- With no force, newton meters need to be adjusted to zero.
- Newton meters should be selected by considering the scale.
- Repeat readings help check for mistakes.
Common misconception
Pupils are often unable to match their experience of different forces with forces in newtons.
Pupils are provided with opportunity to both measure and describe a range of forces.
Keywords
Newton (N) - The size of a force is measured in units called newtons (N).
Newton meter - The size of a force can be measured with a newton meter.
Scale - A scale is a line on which different positions are marked.
Accurate - Results are accurate if they are close to the true value of what is being measured.
Zero error - A zero error is when a measuring device should read zero but doesn’t.
