If m = 100 kg and a = 4 m/s2, than what is the force (f)? n

Force can be defined as change in velocity of an object of mass, m . That is the force is applied to make the object in motion or to accelerate it.

This can be represented as:

F=m\times a

Here,

F denotes the force

m denotes the mass

a denotes the acceleration.

Here the values are given as:

m=100 kg

a=4 m s⁻²

So F=m\times a

F=100\times 4

F=400 N

N denotes newton that is S.I. unit of force that is having dimension as kg ms⁻².

An observation that requires measurement is called Quantitative.

Reason: quantitative- relating to, measuring, or measured by the quantity of something rather than its quality.
