What is the difference between torque and power?

Engineering Explained did a video explaining what is the difference between torque and power. You can find it here.


Watch the first 30 seconds for the definition of torque & then read below for an explanation of power.

He starts off okay when he states

“Torque is force applied at a distance

But from then on I think he goes into the weeds when explaining horsepower.

Short explanation of power

Power is the speed at which the torque is applied.

Example

How much torque can we maintain on a spanner, if the spanner is turning at 2000rpm?

When we know this torque number we can calculate/extrapolate the power being applied to the spanner, at 2000rpm.

Its just than simple.

What is the difference between torque and power?

Torque is the force. Power is the rate at which we can apply that force.
