Force. (vector)
A force is a push or a pull, exerted by one object on another.
In SI force measured in N or kg.m/s2
It has a direction and a magnitude so it is vector
Force (F) = mass (m) x acceleration (a)
Force depends mass and
- Acceleration is directly proportional to force.
- Acceleration is inversely proportional to mass.
The results of the same force exerted on objects of different mass.
