- ⇝Gravitational force
- ⇝ Frictional force

Formula
F = ma
Some basic information about force
S.I unit = N (Newton)
S.I. base unit = kg m/s²
It is a vector quantity. As it has both direction and magnitude.
Dimension =
mass = [M]
acceleration = [LT- ²]
So, dimension of force = ma
= [M] [LT-²]
= [MLT-²]
Example
Pulling of a cart by horse/bull because of force.
