Momentum Momentum is what Newton called the “quantity of motion” of an object. 5/24/2019 http:mrabynum.weebly.com

Momentum The momentum of an object: Depends on the object’s mass. Momentum is directly proportional to mass. Depends on the object’s velocity. Momentum is directly proportional to velocity. 5/24/2019 http:mrabynum.weebly.com

Momentum In symbols: p = mv p m v 5/24/2019 http:mrabynum.weebly.com

Momentum Momentum is a vector quantity. Common units of momentum: kg m/s 5/24/2019 http:mrabynum.weebly.com

Impulse The impulse exerted on an object depends on: The force acting on the object. Impulse is directly proportional to force. The time that the force acts. Impulse is directly proportional to time. 5/24/2019 http:mrabynum.weebly.com

Impulse In symbols: I = Ft I F t 5/24/2019 http:mrabynum.weebly.com

Impulse Impulse is a vector quantity. Common units of impulse: N s 5/24/2019 http:mrabynum.weebly.com

Impulse & Momentum The impulse exerted on an object equals the object’s change in momentum. 5/24/2019 http:mrabynum.weebly.com

Impulse & Momentum In symbols: I = Dp 5/24/2019 http:mrabynum.weebly.com

Conservation of Momentum Since impulse = change in momentum, If no impulse is exerted on an object, the momentum of the object will not change. 5/24/2019 http:mrabynum.weebly.com

Conservation of Momentum If no external forces act on a system, the total momentum of the system will not change. Such a system is called an “isolated system”. 5/24/2019 http:mrabynum.weebly.com

Conservation of Momentum Momentum is conserved in every isolated system. 5/24/2019 http:mrabynum.weebly.com

Conservation of Momentum Another way to think about it is: Internal forces can never change the total momentum of a system. 5/24/2019 http:mrabynum.weebly.com

Conservation of Momentum In practice, for any event in an isolated system: Momentumafter = Momentumbefore 5/24/2019 http:mrabynum.weebly.com
