Mary - Physics

Today for our Double Period of Science with Mr De Soysa, we learnt about the differences between Scalar and Vector Quantities. 

1. Scalar Quantities - This has only a magnitude or size of an object. This has no direction.
2. Vector Quantities - This has both magnitude and direction.

We were given different quantities in Physics where we had to define the meanings of them and also organise them into groups of Scalar Quantities and Vector Quantities. For example, Acceleration is the Rate of change of speed with time or speeding up (ms-2). This is a Vector quantity because it has both magnitude and direction.

Another example is, Deceleration. Deceleration is reducing the acceleration or reducing speed. This is also a Vector Quantity.
