Question

Which statement best describes how work and power are different? (2 points)
Group of answer choices

To find work we need to know force and distance; to find power we need to know force and velocity.

To find work we need to know energy and time; to find power we need to know energy and distance.

To find work we need to know velocity and distance; to find power we need to know distance and time.

To find work we need to know distance and force; to find power we need to know energy and velocity.

Answer 1

Answer: To find work we need to know force and distance; to find power we need to know force and velocity.

Explanation:

First, work is done when force is applied on an object over a distance.

i.e Work = Force x Distance

Next, Power is the rate of work done per unit time i.e Power = work / time

When combined, power can be expressed as:

Power = (Force X Distance) / Time

(Now, since velocity is defined as distance covered divided by time taken:

velocity = distance / time);

Then, power is then expressed as:

Power = Force x velocity

Thus, to find work we need to know force and distance; to find power we need to know force and velocity
