Formulas Flashcards
1
Q
SPEED
A
𝑠𝑝𝑒𝑒𝑑=𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒/𝑡𝑖𝑚𝑒 or 𝑣=𝑠/𝑡
2
Q
VELOCITY
A
𝒗𝒆𝒍𝒐𝒄𝒊𝒕𝒚=𝒅𝒊𝒔𝒑𝒍𝒂𝒄𝒆𝒎𝒆𝒏𝒕/𝒕𝒊𝒎𝒆
3
Q
DISTANCE
A
𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒=𝑠𝑝𝑒𝑒𝑑×𝑡𝑖𝑚𝑒
4
Q
Converting, km to m (vice versa)
A
/3.6 or x3.6
5
Q
ACCELERATION
A
𝑎=(𝑣−𝑢)/𝑡
acceleration= final-initial/time
6
Q
EQUATIONS FOR MOTION
A
𝑣=𝑢+𝑎𝑡
𝑣^2=𝑢^2+ 2𝑎𝑠
𝑠=𝑢𝑡+1/2 𝑎𝑡^2
7
Q
GRAVITY instead of acceleration
A
gravity equals -9.8m/s -2. use this for acceleration
