Understanding Horsepower and Torque

What is the definition of horsepower?

• A measure of the rotational force applied to an object.

• A unit of power that measures the rate at which work is done.

• The amount of energy required to move a vehicle.

• The speed at which a vehicle can travel.

What is the definition of torque?

• A measure of the rate at which work is done.

• A unit of power used to describe engine output.

• A measure of the rotational force applied to an object.

• The speed at which a vehicle can travel.

How are horsepower and torque related in vehicles?

• Horsepower is always greater than torque.

• Torque is always greater than horsepower.

• Horsepower is derived from torque and engine speed.

• They are unrelated and independent of each other.
