Speed, Velocity And Acceleration Flashcards
1
Q
Formula to find distance/speed/time
A
D
———
S x T
(Draw it in a triangle, cover the one you’re trying to find. Eg. Tying to find time, divide the distance by speed)
2
Q
Unit of speed
A
Metre per second, m/s
Or
Kilometre per hour, km/h
3
Q
What is velocity
A
The velocity of an object is its speed in a certain direction
4
Q
What is the unit of velocity (what is it measured in)
A
Like speed, m/s or km/h
5
Q
What is acceleration
A
The rate of change of velocity (or speed)
6
Q
Formula to find acceleration
A
(Final velocity)-(initial velocity)
—————————
Time taken
7
Q
Unit of Acceleration
A
m/s/s metre per second per second
m/s2 (can’t do squared) metre per second squared
8
Q
Formula for average speed
A
Distance travelled
—————————
Time taken
