If you have ever tightened a bolt with a wrench, or tried to get the lid off a jar of strawberry jam, then you have dealt with the concept of torque — a twisting action or a turning force.
The word torque, which rhymes with fork, is used in the field of physics as a measure of rotational force. For example, how much strength does it take to move an object, such as a screwdriver, around an axis, such as a screw? In ancient times, a torque was a necklace made of twisted metal. Now, torque is commonly used to describe the power of sports cars and their ability to accelerate, since car engines operate with rotating parts.
