What is a Newton?
What is a Newton?
The unit used to measure force. It's named after Sir Isaac Newton, a famous physicist who studied forces.
What is a Newtonmeter?
What is a Newtonmeter?
A device that measures the strength of forces. It works by stretching when a force is applied.
What is a non-contact force?
What is a non-contact force?
A force that acts upon an object without physical contact. Air resistance is an example.

Study Notes
Squashing and Stretching
- Newton is the unit of force
- Newton metre is the unit of force
- Air resistance is a non-contact force
- Magnetism is a non-contact force
- Interaction pairs of forces
Force (N) vs Extension (mm)
-
1 N = 4 mm (extension)
-
2 N = 82 mm (extension)
-
3 N = 107 mm (extension)
-
4 N = 120 mm (extension)
-
5 N = 152 mm (extension)
-
The higher the force, the more the extension will expand
-
Starting length = 53 cm
