Question

Derive the relation between power and force and write the SI unit of power​

Answer 1

Answer:

Force Power

Definition A push or a pull resulting from an interaction between objects. Power is the rate at which work is done, or energy is transmitted.

Unit newton watt = joules/second

Symbol F P

Named After Isaac Newton James Watt

Derivations from other quantities F = m a (force = mass multiplied by acceleration) P = w/t (power = work divided by time)

Relation to “Work” Force applied over a distance creates work. Rate at which work is performed.

Everyday Example Gravity, friction, magnetism. Horsepower (1 horsepower = 750 Watts)

Answer 2

❒ Relation between power and force:

$\qquad \diamond$ Power = Force × velocity

$\qquad : \sf \Longrightarrow P = FV$

$\sf\blue\large{\underline{\underline{❒ \: SI \: Units :}}}$

1. Force:-

• SI Unit of force is Newton (N).
• Force = mass × acceleration.

2. Power:-

• SI Unit of power is watt (w).
• Watt (w) = One joule of work done per second.
