1
Q
What are are the features of scalar quantity?
A
- Only have a magnitude (size)
- Do not have a direction
2
Q
What are the features of a vector quantity?
A
- Has a magnitude
- Has a direction
3
Q
What does average speed =?
A
average speed = total distance/ total time
4
Q
What is the equation for velocity?
A
acceleration = change in velocity/ time taken
5
Q
What is distance?
A
How far an object moves. Distance is a scalar quantity.
- This is because it contains a magnitude but not a direction.
6
Q
What is displacement?
A
The distance an object moves in a straight line from a starting point to a finishing point. Displacement is a vector quantity.
- This is because it contains a magnitude and a direction.
7
Q
What is velocity?
A
displacement/ time
