1

Work done =

Force * Distance
W.D = Fs

2

acceleration =

a = (v² - u²) / 2s

3

v² =

v² = u² +2as

4

Kinetic Energy =

K.E = 1/2 mv²

5

Force =

F=ma

6

Power =

P = Fv

7

Word done =
(Using v)

W.D = 1/2 mv² - 1/2 mu²

8

Work done
(K.E)

Work done = Increase in KE

9

Potential Energy =

P.E = mgh

10

Potential Energy =
Using v

mgh = 1/2 mv² - 1/2 mu² = P.E

11

Conservation of momentum

mv = mv

12

(Coefficient of restitution) e =

e = speed of separation / speed of impact

13

Friction =

Fᵣ = μR
(R = Reaction force)

14

What is μ?

Coefficient of fiction
