Question

When describing how power and work are similar you would want to mention that a you must know time to determine both work and power. b you must know force in order determine both workand power. c you must know energy in order to determine both work and power. d you must know velocity to determine both work and power?

Answer 1

The answer that would best complete the given statement above would be option B. When describing how power and work are similar you would want to mention that you must know force in order determine both work and power. Hope this answers your question. Have a great day!

Answer 2

Answer:

You must know force in order determine both work and power.

Explanation:

Work done is defined as the product of the force and the displacement. Mathematically, it can be written as :

W = F × d

$W=Fdcos\ \theta$

$\theta$ is the angle between the force and the displacement.

The power of an object is defined as the rate at which the work is done. It can be written as:

$P=\dfrac{W}{t}$

here w is the work done and t is the time taken.

So, in order to determine both power and the work the applied force must be a known quantity.

Hence, the correct option is (b) " you must know force in order determine both work and power ".
