So we want to find the power output of a motor that can exert a force of 10 newtons to push an object 2 meters in one second.
00:07
So the formula for power is equal to the total work done divided by the change in time.
00:16
So what do we know from here? so to find power, we need to know the work done and the change in time.
00:21
Well, we know the change in time.
00:23
The change in time is simply one second because that's how long it takes the motor to move the object.
00:29
So how do we find work? well, we have a separate formula for work, which is work is equal to force times displacement, whereas displacement.
00:37
So force, we're given is 10 newtons times displacement is 2 meters.
00:44
And so 10 times 2 is 20, newtons times meters...
