Impulse And Momentum

Question 1

What is the equation of momentum

Answer 1

Mass x velocity (kgm/s)

Question 2

What is the equation of impulse

Answer 2

Force x time = change in momentum

Ft= mv-mu

Question 3

Varying force

Answer 3

Integrate T2-T1 F dt = m(v-u)= I
Where v= f(t)

Question 4

Conservation of momentum

Answer 4

M1u1 + M2u2 = M1v1 + M2v2

Question 5

Final momentum

Answer 5

Initial momentum + impulse

Question 6

Newtons law of impact

Answer 6

Speed of separation/ speed of approach = constant (e) (coefficient of restitution)
