To measure the size of a force, you can use a ______ meter.
- 'newton' ✓
Which gives the correct ways of writing the unit forces are measured in?
- newtons (n)
- newtons (N) ✓
- Newtons (n)
- Newtons (N)
What does this newton meter read?
- 3.1 N
- 3.5 N ✓
- 3.7 N
- 4.0 N
Which of the below are ways to read a newton meter more accurately? Tick as many as you think.
- Take repeat readings to check for mistakes. ✓
- Check the newton meter reads zero with no force applied (check for a zero error) ✓
- Use a newton meter with the biggest possible range.
What does this newton meter read?
- 8.3 N
- 8.6 N ✓
- 8.7 N
- 8.8 N
- 9.0 N
This newton meter has masses attached, applying a force. What is the issue and how should it be solved?
- A zero error, all measurements are too high. Use the adjustment screw.
- A zero error, all measurements are too low. Use the adjustment screw.
- The force applied is beyond the range. Use a newton meter with a greater range. ✓
- The scale interval is too big. Use a newton meter with a smaller scale interval.

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.

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.
