- Mathematically, it is expressed as: Velocity=DisplacementTime - Velocity is a vector quantity, which means it has both magnitude (how fast something is moving) and direction (the way in which it is moving). 3.
Speed is a scalar quantity, which means it only has a magnitude and no direction. On the other hand, velocity is a vector quantify, which means it has both a magnitude and a direction. For the purpose of introducing the concepts of average and instantaneous velocity in an easy-to-...
Speed is only dealing with scalar quantities, which means it only has units like metres, kilometres, etc.Velocity is a vector quantity, which means it must includes directions such as south, north, east, west etc.Hope this may help you a little bit.
Velocity is commonly defined as the change in distance over an amount of time. It is a vector quantity which means that it has both magnitude and direction. It is commonly measured in {eq}\dfrac{m}{s}, \dfrac{km}{h}, \dfrac{ft}{s},\ \text{or}\ \dfrac{mi}{h} ...
Velocity is a vector quantity: it has both magnitude and direction. Speed is the magnitude of the velocity: no direction is associated with speed. 2. (b) 3. (c) 4. 144 ft; 96 ft/s downward; zero 5. 4 s; 12 ft 6. 450 m/s2 7. The magnitude of A→+B→ is 32 units and ...

Velocity is a vector quantity (because it has magnitude as well as direction). For example, the expression ’25 km per hour7 is the speed (because it has magnitude only), but the expression 25 km per hour towards North (or any other direction) is velocity (because it has both magnitude...
Velocity is a vector quantity that denotes “the rate at which an item changes location.” Consider a person who takes one step forward and one step back at a quick pace, constantly returning to the same starting place. While this would cause a flurry of activity, it would also result in...
Because it has direction as well as magnitude, velocity is known as avectorquantity and cannot be specified completely by a number, as can be done with time or length, which are scalar quantities. Like all vectors, velocity is represented graphically by a directed line segment (arrow) the le...
Speed is a scalar quantity, which means it only has magnitude and doesn't have a direction. It tells us how fast an object is moving without regard to its direction. On the other hand, Velocity is a vector quantity, meaning it has both magnitude and direction. This distinction makes ...
