physics equations

Question 1

force

Answer 1

f = ma

Question 2

acceleration (change in velocity)

Answer 2

a=(v-u)/(t)

Question 3

= 2ax

Answer 3

(v^2) - (u^2) = 2ax

Question 4

make x the subject

Answer 4

x = (v^2) - (u^2) / 2a

Question 5

make v the subject

Answer 5

v = at + u

Question 6

make u the subject

Answer 6

u = v - at

Question 7

stopping distances

Answer 7

thinking distance + braking distance

Question 8

momentum

Answer 8

p = mv

Question 9

force (change in velocity)

Answer 9

f = (mv)-(mu)/t
