Momentum Flashcards
1
Q
What is the equation for linear momentum?
A
p = mv momentum = mass x velocity
2
Q
What does the conservation of momentum state?
A
Within a closed system, the total momentum in any specific direction remains constant
3
Q
Is momentum a scalar or a vector quantity?
A
Momentum is a vector quantity
4
Q
What is the momentum of an object with mass of 4.5kg moving at a speed of 10m/s?
A
45 kgm/s
5
Q
What are the similarities and differences of ‘perfectly elastic’ and ‘inelastic’ collisions?
A
Similarities
Momentum is conserved for both
The total energy is conserved for both
Differences
Kinetic energy is conserved for perfectly elastic, but kinetic energy is not conserved for inelastic
