**1 (c) List the vectors and scalars from distance, displacement, length, speed, velocity, time, acceleration, mass and force.**

I already explained the terms scalars and vectors in my post here. It is extremely easy to differ between a scalar and a vector, and to pick them out once you have understood the two terms. I'll now explain how each of the quantities listed above is a scalar or a vector.

**Distance**

**Displacement**

**Displacement can be defined as the**

**shortest**distance between two points. As the shortest distance is always in a straight line, it has a direction. Therefore it is a vector. Remember both distance and displacement have the same unit. To better help you understand the difference between distance and displacement, I'll present a scenario to you.

A car travels from Multan to Lahore over a total distance of 300 km. Now, the car does not travel in a straight direction towards Lahore from Multan, but has to travel by road.

You can see the car does not have any particular direction while going by road. Now if an airplane was going to Lahore instead, it would travel in a straight direction.

**Length**

**Speed**

**distance.**As i explained earlier that distance is a scalar, so speed is a scalar too as it is derived from distance.Also, the other quantity speed is made of is time. It is obvious that time does not have any direction. Thus speed is a scalar.

**Velocity**

**Time**

**Acceleration**

**Mass**

**Force**
