power
Power = (work) divided by (time) If you don't know the amount of work, you can calculate it. Work = (force) times (distance).
I usually start with the definition of work: Work = force * distance so... Force = work / distance Distance = work / force So, no. You had it backwards.
No. Velocity = distance divided by time. Example: a body covers 100 metres distance in 10 seconds velocity = 100 / 10 = 10 m/s
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
