Question

A particle accelerated uniformly from rest by a
force delivering constant power. Then velocity is
directly proportional to (t = time) :

Answer 1

Answer:

velocity......... t time

Answer 2

Velocity and time are proportional as follows:

Explanation:

• We can say that the distance travelled is directly proportional to the velocity. General Guidelines: When we claim that two variables, x and y, are directly proportional, we indicate that the ratio x/y remains constant while x and y vary.
• When two quantities are proportional, it means they are proportional in the same way.

• During uniformly accelerated, straight-line motion, the relationship between velocity and time is straightforward.
• The greater the difference in velocity, the longer the acceleration.
• When acceleration is constant, the change in velocity is proportional to time.
