J/s = N*m/sA joule is a unit of measure of WORK, and a second is a unit of measure of TIME. POWER=WORK/TIME. How do you get velocity from that?

J/s = N*m/s
A.T. said:J/s = N*m/s
m/s is a unit of velocityHow do you get VELOCITY from that?
YesIs lifting 50 lbs 10 feet not the same work as lifting 10 lbs 50 feet?
YesIf the work is the same and the time is the same at 3 seconds, then the power is the same,
And neither is forcebut the velocity is not the same.
You claim power=force*velocity.
I lifted a 29 lb object at a velocity of 16 ft/s. How much work was done?
That's a formula for power, not for work.
Because you didn't ask about power.you did not tell me the power. Why not?
Because you didn't ask about power.
So let's apply your logic to a simple example:
You lift a 100 lb rock 10 feet away from the center of the earth. How much energy is that, 1,000 joules?
No. There is no weight at the center of the Earth and the offset 10' from center can't be calculated, since the errors in modeling the Earth as a perfect sphere are greater than the minuscule gravitational differential at that coordinate.
Read post 53 or 55. Sheeze, dude!A joule is a unit of measure of WORK, and a second is a unit of measure of TIME. POWER=WORK/TIME. How do you get velocity from that?
Read post 53 or 55. Sheeze, dude!
I said I lift it away from the center of the earth, I didn't say it was at the center of the earth and then lifted away. If I lift a rock off the ground in a direction away from the center of the earth it doesn't mean that I lifted the rock from the center, it means I lifted the rock in a direction AWAY from the center of the earth. It's just like you to come up with some BS because your BS is just that, BS!
0.84hpi gave you the force and velocity. How much hp is that?
I just got here. I see your panties are pre-wadded for me. Has the wind machine guy been torquing your wrench?
Seems you answered yourself twice. POWER = force*velocity. Simple.Read, and more importantly UNDERSTAND post #62, DUDE.
How do you torque a wrench?
0.84hp
That's about all you can do with a wrench unless you're one of those guys that opens your beer with them.
