The Law of Conservation of Momentum

Momentum and Impulse Unit 6. Momentum (p) Definition- The amount of motion an object has. (vector quantity) units- kg∙m/s p = mv.

Momentum – Part 2 Conservation of Momentum. The law of conservation of momentum tells us that as long as colliding objects are not influenced by outside.

Gravity Chapter 3 Section 2.

 Momentum – the motion of mass  If an object is moving, it has momentum ▪ An object with lots of momentum will be hard to stop. ▪ An object with little.

Momentum. What is Momentum? Momentum – tendency of objects to keep going in the same direction with the same speed –Depends on mass and velocity –Has.

Conservation of Momentum. Momentum  The velocity and mass of an object give it momentum.  The larger the velocity and mass, the larger the momentum.

DAILY QUESTION January 20, What is Newton’s 3 rd law?

Momentum Anything which is moving has MOMENTUM. The amount of momentum it has depends on:- 1. MASS (kg) 2. VELOCITY (m/s)

1. How does the change in momentum compare between a quick stop (collision) and a controlled stop (braking) from the same velocity? Why?

Momentum Chapter 2.3

Momentum, Mass, and Velocity Momentum (p): the product of the mass and velocity of an object The more momentum an object has the harder it is to stop or change its direction

Calculating Momentum Momentum: Mass of an object multiplied by its velocity P=M X V Unit: kg*m/s

Law Conservation of Momentum States that when any time objects collide, the total amount of momentum stays the same When a moving object hits another object, some or all of the momentum of the first is transferred

Practice Problems Find the momentum of the different balls m= .045 kg m=.168 kg m= .575 kg V= 16 m/s upward v=3 m/s forward v= 9.2 m/s east At a rodeo, a bucking bronco throws an 81 kg rider into the air at a velocity of 10 m/s upward. What is the riders momentum? What is the velocity of a 55 kg skater who has a momentum of 440 kg×m/s forward?
