Moments and Momentum

Question 1

What is the equation for moments?

Answer 1

Moment = Force x Distance
M = F d

Question 2

Define law of moment

Answer 2

Sum of all anti-clockwise moments around a point are equal to all the sum of all the clockwise moments about a point

Question 3

What is the equation for momentum?

Answer 3

Momentum = Mass x Velocity
p = m x v

Question 4

Define impulse

Answer 4

Change in momentum

Question 5

What is the equation for impulse?

Answer 5

Change in momentum = mass x change in velocity
p = m x (Vf-Vi)

Impulse = Force x Time
F t = m v
F = m(Vf-Vi)/t

Question 6

What is the formula for the collision of 2 objects (2 -> 1)?

Answer 6

(m1 Vi1) + (m2 vi2) = (m1 + m2)Vf

Question 7

What is the formula for the collision of 2 objects (1 -> 2)?

Answer 7

(m1 + m2)Vi = (m1 Vf1) + (m2 Vf2)

Question 8

What is the formula for the collision of 2 objects (2 -> 2)?

Answer 8

(m1 Vi1) + (m2 Vi2) = (m1 Vf1) + (m2 Vf2)
