What is a vector quantity?

What is a scalar quantity?

A vector is a something that has a magnitude and a direction eg force velocity displacement weight acceleration.

A scalar is something that has magnitude only not a direction. Eg distance speed mass energy

2

What is speed and velocity?

How do you work it out?

Speed is just how fast you’re going with no regard to the direction
Velocity is speed in a given direction

Distance m = speed m/s x time s

3

What are some average speeds?

Walking
Running
Cycling 1.4m/s
Cars slow 13 m/s
Cars fast 31 m/s
Trains 55m/s
Aeroplanes 250m/s
Ferries 15m/s
Wind 5-20m/s
Sound in air 349m/s
