Speed, distance and vectors

Question 1

What do vectors have?

Answer 1

Vectors have magnitude and direction

Question 2

What is magnitude?

Answer 2

magnitude is size

Question 3

Can you give any examples of vectors?

Answer 3

force, velocity, displacement, weight, acceleration and momentum

Question 4

How do we remember this?

Answer 4

Most vectors do ask for direction

Question 5

What makes a scalar quantity?

Answer 5

Scalars only have direction, not magnitude

Question 6

Can you give any examples of scalar quantities?

Answer 6

speed, distance, mass, energy, temperature, time

Question 7

What is the difference between speed and velocity?

Answer 7

Velocity has direction, speed doesn’t

Question 8

What is the difference between distance and displacement?

Answer 8

Distance is how far an object has moved, without direction.

Displacement is the distance from a starting point to a finishing point with direction

Question 9

What is an example of displacement?

Answer 9

5m north then 5m south

distance is 10m but the displacement is 0m as you ate back at the starting point

Question 10

What is the speed, distance and time equation?

Answer 10

Distance= speed x time 
speed= distance/ time

Question 11

What are examples of objects constant speed?

Answer 11

walking- 1.4m/s
running- 3m/s
cycling- 5.5m/s
trains- up to 55m/s
aeroplanes 250m/s
