This isn't homework. I've been thinking.
If I have say a 1kg mass and I want to accelerate it at 1m/s^2 for 10m, I would calculate the work to be done as 10J.
Force = 1kg x 1m/s^2 = 1N
Work = 1N x 10m = 10J
I hope that is correct so far.
But what confuses me is power. Power is work/time, but how could I possibly alter the amount of time it takes for me to accelerate a mass for a certain distance? Wouldn't time be constant?
Is it possible for me to accelerate the mass at 1m/s^2 and then to reach 10m with different amount of times?
Thanks a lot.
