Vectors and scalars

Question 1

What is a scalar?

Answer 1

A scalar quantity is fully defined by its magnitude and unit

Question 2

What is a vector?

Answer 2

A vector is fully defined by its magnitude and direction

Question 3

What is displacement?

Answer 3

Displacement is the shortest distance from your initial position to your final position. Therefore, displacement is a measurement of distance

Question 4

What equation do you use to work out a bearing

Answer 4

c= tan-1 (a/b)

Question 5

How would you work out a displacement?

Answer 5

You could work out displacement by using Pythagorus theory.

Question 6

What is another way to work out displacement with an equation if you have been given time and velocity?

Answer 6

S=VxT
