Distance, Displacement, Speed And Velocity Flashcards
1
Q
What is a vector quantity?
What is a scalar quantity?
A
A vector is a something that has a magnitude and a direction eg force velocity displacement weight acceleration.
A scalar is something that has magnitude only not a direction. Eg distance speed mass energy
2
Q
What is speed and velocity?
How do you work it out?
A
Speed is just how fast you’re going with no regard to the direction
Velocity is speed in a given direction
Distance m = speed m/s x time s
