Topic 1.3: Vectors and Scalars

Question 1

What are scalar measurements?

Answer 1

Measurements that only includes size (magnitude)

e.g., distance, mass, speed, energy, pressure

Question 2

What are vector measurements?

Answer 2

Measurements that include size (magnitude) and direction

e.g., force, displacement, velocity, acceleration

Question 3

What are component vectors?

Answer 3

Vectors that follow each other

They also make up resultant vectors

Question 4

What are resultant vectors?

Answer 4

Vectors that go in the opposite direction to each other

Are made of component vectors

Question 5

What is the rule that allows vectors to be ressolved?

Answer 5

Any vector can be turned into 2 component vectors at 90 degrees to each other

Question 6

What do you have to do when drawing free body diagrams?

Answer 6

Show all forces acting on a body to correct scale and direction

Question 7

What type of measurement do you get if you multiply a vector and a scalar?

Answer 7

A vector

e.g., acceleration * mass = force
