1
Momentum Momentum is _____________________ Momentum = P = Units = Momentum is a vector quantity – it has _________ and _________ SO: the bigger the object, the _______ to stop MOMENTUM IS CONSERVED !
2
Momentum Momentum is _____________________ inertia in motion Momentum = mass x velocity P = mv Units = kg m/s Momentum is a vector quantity – it has _________ and _________ direction magnitude SO: the bigger the object, the _______ to stopharder MOMENTUM IS CONSERVED !
3
Law of Conservation of Momentum: In the absence of an external force, the momentum of a system__________________. Momentum Start = _____________________
4
MOMENTUM IS CONSERVED ! Law of Conservation of Momentum: In the absence of an external force, the momentum of a system__________________. remains unchanged Momentum Start = _____________________ Momentum Finish
5
Types of Momentum Elastic Collisions (________) – when objects don’t ________. Momentum is transferred without ___________. Elastic Collision Example: 1kg 10m/s0m/s What if? 1kg5kg1kg5kg 10m/s0m/s
6
Types of Momentum Elastic Collisions (________) – when objects don’t ________. Momentum is transferred without ___________. bouncy attach loss or gain Elastic Collision Example: 1kg 10m/s 0m/s What if? 1kg5kg1kg5kg 10m/s0m/s ?

1kg5kg1kg5kg 10m/s0m/s P in = P out P in = mv P out = mv
8
1kg5kg1kg5kg 10m/s0m/s ? P in = P out P in = mv = 1kg (10m/s) = 10kgm/s 10kgm/s = 5kg (v) P out = mv 10kgm/s = v 5kg 2 m/s = v
9
Inelastic Collision Inelastic Collisions (_____) – when objects ______. __________ momentum. Inelastic Collision Example: 1kg 10m/s0m/s +
10
Inelastic Collision Inelastic Collisions (_____) – when objects ______. __________ momentum. sticky attachShared Inelastic Collision Example: 1kg 10m/s0m/s + 2kg
11
Inelastic Collision Example: 1kg 10m/s0m/s + 2kg P = mv + mv P in = P out
12
Inelastic Collision Example: 1kg 10m/s0m/s + 2kg P = mv + mv = (1kg)(10m/s) + (1kg)(0m/s) = 10kgm/s + 0 P = 10kgm/s P in = P out 10kgm/s = mv 10kgm/s = 2kg(v) 10kgm/s = v 2kg V = 5m/s
