Scalar And Vector

By Boyang Zhao

The major difference between a scalar quantity and a vector quantity is that vector has a direction. A scalar is only represented by its magnitude and has no direction. Examples for scalars include mass, temperature, speed, and energy. On the other hand, a vector has both direction and magnitude. Examples for vectors include velocity, acceleration, and force.

Scalar: speed - a car is traveling 5 miles per hour
Vector: velocity - a car is traveling 5 miles per hour northward.
