Answer:
A force has both magnitude and direction, therefore: Force is a vector quantity; its units are newtons, N. Forces can cause motion; alternatively forces can act to keep (an) object(s) at rest. ... Consider two forces of magnitudes 5 N and 7 N acting on a particle, with an angle of 90◦ between them.

Answer:
Electric force results form mutual interactions between two charges.
Answer: HP = Horse Power.
Explanation: it is the unit given to tell the motor's particular power and 1hp = 746 watts.
The quantity can be work or kinetic energy or potential energy. Work is same as the energy.
Work done can be described as energy transferred from and object when a force is applied along a displacement. That is work done is the product of force in the direction of the displacement and the magnitude of the displacement.
Mathematically it can be represented as,
W = F x d
where,
W ⇒ work done
F ⇒ force acting along the displacement
d ⇒ magnitude of displacement
We know,
force = mass x acceleration
∴ the unit of force is kgms⁻²
The unit of work done will be kgms⁻² x m
That is kgm²s⁻²
where m is the unit of displacement that is meter (m)
Hence kgm²s⁻² is the unit for work or energy
