Vector quantity. Pair of vectors with equal magnitude, opposite direction. 13 Compare with Definitions Torque Rotational force applied at a distance from an axis. The motor's torque turns the shaft. 3 Couple Two equal forces acting in opposite directions. The steering wheel's turn is due to ...
Quantity refers to the amount or number of something, while a unit is a standard measure used to express that quantity.
Yes, velocity can change even if speed remains constant because velocity is a vector quantity that includes both speed and direction. If an object moves at a constant speed but changes its direction, its velocity changes. This is often seen in circular motion, where the speed may stay the sa...
A vector is a quantity that has both a direction and a magnitude. A magnitude is an abundance or a mathematical amount of something. Displacement is also a vector quantity, which is the difference in distance from a starting point to an endpoint. For example, if a car drives 5 miles to...
