Formula for Force
The quantity of force is expressed by the vector product of mass (m) and acceleration (a). The equation or the formula for force can mathematically be expressed in the form of:
F = ma
Where,
- m = mass
- a = acceleration
It is articulated in Newton (N) or Kgm/s2.
Acceleration a is given by
a = v/t
Where
- v = velocity
- t = time taken
So Force can be articulated as: F = mv/t
Inertia formula is termed as p = mv which can also be articulated as Momentum.
Therefore, Force can be articulated as the rate of change of momentum.
F = p/t = dp/dt
Force formulas are beneficial in finding out the force, mass, acceleration, momentum, velocity in any given problem.
Unit of Force
In the centimeter gram second system of unit (CGS unit) force is expressed in dyne.
In the standard international system of unit (SI unit) it is expressed in Newton (N).
Types of Force
Force is a physical cause that can change the state of motion or the dimensions of an object. There are two types of forces based on their applications:
- Contact Force
- Non-Contact Force
