- Upthrust - upwards force on a body caused by water being displaced around it. This is sometimes called Buoyancy
- Lift - upwards forces on aeroplanes (or airborne objects (not a ball or similar))
- Thrust - forwards force created by a body (push)
- Weight - force due to gravitational attraction (Gravitational force)
- Friction - force caused by rubbing of surfaces that opposes motion
- Drag - frictional force caused by air particles colliding with a body that opposes motion
- Magnetic - force caused by magnetic attraction
- Electrostatic - force caused by attraction between charges
- Normal reaction - force created by a body as a reaction to a force being applied
Descriptions of forces:
- Compression - the force on a body when it is being squashed
- Tension - the force on a body when it is being stretched
- Contact forces - forces that require to be touching to have an effect (e.g. friction, normal reaction)
- Non-contact forces - forces that do not require to be touching to have an effect (e.g. magnetic, electrostatic)
