Linear Momentum Flashcards
1
Q
Momentum
A
p= m*v
2
Q
Force in Relation with Momentum
A
Force = dp/dt
3
Q
Impulse
A
I= Δp I= FΔt I= int(F(t))
4
Q
Elastic Collision
A
- When kinetic energy is conserved
m1v1i + m2v2i = m1v1f + m2v2f
5
Q
Inelastic Collision
A
- When kinetic Energy is not conserved
6
Q
Perfectly Inelastic Collision
A
-When the two particles stick together
m1v1 + m2v2= (m1 + m2)v’
