Chapter 1 Force and Momentum Flashcards
0
Q
Unit of Momentum
A
Newton second(Ns) or kilogram per second (kgms^-1)
1
Q
Area under line of a force-time graph represents the?
A
Change in momentum or impulse
2
Q
Calculating impact force
A
A=(v-u)/t
Change of momentum / time taken
3
Q
Principle of Conservation of Momentum
A
System interacting objects, total momentum remains constant, provided no external resultant force acts on the system
4
Q
Elastic collision
A
No loss of kinetic energy
5
Q
Inelastic collision
A
Colliding objects stick together
6
Q
Partially inelastic collision
A
Colliding objects move apart and have less kinetic energy after the collision than before
