Contact and non-contact forces
The main types of forces that you will meet can be divided into contact and non-contact forces.
Contact forces – the environment can provide support:
- Compression force (a warp force).
- Tension force (a warp force).
- Buoyancy.
Contact forces – reduce, or prevent motion through an environment:
- Grip.
- Slip.
- Drag.
Non-contact forces – allow remote parts of the environment to affect an object:
- Gravity force.
- Magnetic force.
- Electric force.
The space throughout which non-contact forces act is referred to as a field
. The field specifies the strength and direction of the non-contact force acting.
