The horsepower of a car is what keeps the car going at a certain speed. It is also what keeps the engine or motor running smoothly once it is up to speed.
Horsepower is measured in foot-pounds per second.
Torque is what gets the car up to speed. Torque is the force used to rotate an object.
Torque is a measurement said as pound-feet.
Low 0-60 numbers are thanks to a large amount of torque. Then a large amount of horsepower gives you a smooth ride at the fast speed.
An engine that makes more torque has more potential for work. Additionally, an engine that produces more horsepower can make more torque.
Race cars put a high amount of torque through their system to go fast because they are light. A tractor is heavy so a high amount of torque gets used to push and pull things.
The same high horsepower engine lets one go fast and the other be a workhorse. The weight of the vehicle is what contributes to the use of the horsepower and torque.
Equation for Torque
The torque equation is Force multiplied by Distance.
T = F * D
The bigger the distance, the greater the torque will be.
