Types of FORCE
-Physiotherapy / Biomechanics
1) External Force
2) Internal Force
-Physics / Mechanics
1) Contact Force
2) Non-Contact Force
External Force
-Definition = Push or Pull exerted from the source outside the body
-Examples = 1) Gravitational Force
2) Wind
3) Water

5) Other Object
-Gravitational Force / Gravity = Attraction of earth's mass to another mass, is an external force that under normal conditions constantly affects all object.
- Weight = It is pull of gravity on object's mass with an acceleration of 9.8 meter per second square
W = mass * Gravitational acceleration
W = m * g
g = 9.8 meter per second square
- Unit of weight
