- 1How would you define a vector?A vector quantity is defined by magnitude AND direction.
- 2How would you define a scalar?A scalar quantity is defined by magnitude only.
- 3What is the difference between distance and displacement?Distance is described by magnitude only. Displacement includes both magnitude and direction.
- 4What is the equation for speed?average speed = distance/time
- 5What is the equation for velocity?Average velocity = displacement/time
- 6How to you add vectors?Must makes sure that vectors are 'tip to tail' and used in a scale diagram.
- 7How do you add vectors at right angles?It is easier to use Pythagoras to find the resultant and trigonometry to find the angle.
