Formulas

Question 1

Conservation of momentum

Answer 1

m1v1+m2v2=(m1+m2)vf

Question 2

Kinetic Energy

Answer 2

1/2mv^2

Question 3

Kinematic Equations

Answer 3

The Four Kinematic Equations:
1. Final Velocity:
v = v₀ + at

2. Displacement (Average Velocity):
   Δx = (v + v₀)/2 * t
3. Displacement (Initial Velocity and Acceleration):
   Δx = v₀t + 1/2at²
4. Final Velocity Squared:
   v² = v₀² + 2aΔx

Question 4

Newtons Law of Universal Gravitation

Answer 4

F = G [(M1m2)/r^2]

Question 5

Impulse

Answer 5

Impulse is the change of momentum
Delta p = F\Delta t
Delta p = Change in momentum
F = applied force
Delta t = elapsed time

Question 6

Force

Answer 6

F = m*a

Question 7

Half Life

Answer 7

N(t)=N(0)e^(lamda*t)

T1/2 = ln(2) / lambda

Question 8

Poisson Standard Deviation

Answer 8

square root of the total number of events or samples. (N^1/2)

Question 9

Poisson Relative Standard Deviation

Answer 9

Standard deviation divided by the number of events or samples. (N^1/2)/N
