Momentum Flashcards
1
Q
Momentum = ————– x —————
A
mass ( Kg ) , velocity (m/s)
Greater the mass or velocity = greater the momentum
2
Q
Is momentum scaler or vector ?
A
vector
3
Q
Is momentum always equal ?
A
yes In a closed system, total momentum before an event is equal to the total momentum after an event = conservation of momentum
4
Q
Explain the term conservation of momentum
A
In a closed system, total momentum before an event is equal to the total momentum after an event = conservation of momentum
