December 12 Physics
In: A car (mass=500 kg) going 50 m/s north collides with a truck (mass=2000 kg) going 60 m/s south. Afterwards the car is going 20 m/s south. How fast is the truck going?
Objective: To prepare for and take a quiz. Success criteria: To be able to do problems with bouncing, sticking and recoil collisions.
An offensive player (mass=100 kg) running at 10 m/s to the north is hit by a defensive player (mass=180 kg) running at 5 m/s south. They hold onto each other and go at what velocity?
Boat #1 (mass 600 kg) going 20 m/s to the right is hit by boat #2 (mass 1100 kg) going 12 m/s to the left. Afterward boat #1 is going 5 m/s to the left. How fast is boat #2 moving?
A 3 kg bomb is ticking away when it suddenly explodes into 2 pieces. One piece is 1 kg and goes 50 m/s to the north. How fast does the other part go?
What is the most important idea about momentum?
Momentum and Collisions
Aim: What is the law of conservation of momentum? Do Now: A 20 kg object traveling at 20 m/s stops in 6 s. What is the change in momentum? Δp = mΔv Δp.

Physics Section 6.3 Apply the physics of collisions Inelastic collision – two objects stick together after colliding. The two objects become one object.
Journal 1/27/15 Momentum is the basic idea behind weapons like guns. What kind of defensive thing might we create using momentum or collisions? Objective.
Warm-up U7-#1 1/13/14 1) What is the force felt on a 3200kg truck moving at 16 m/s which runs into a haystack bringing the truck to a stop in 25.6 seconds.
Chapter 6 Momentum and Impulse
Science CBA #2 Review.
Collision Lab and conservation of momentum This “conservation” law is one of the biggest ideas in physics and motion.
Conservation of Momentum. Conserved Total momentum of a system before and after an interaction remains constant Momentum before = Momentum After Two balls.
Chapter 6 Momentum and Impulse. Momentum The product of an object’s mass and velocity: p = mv Momentum, p, and velocity, v, are vector quantities, meaning.
Ch 6 Momentum and Collisions. Lab Day Objective In this chapter we will learn: – How to calculate momentum and impulse – Conservation of Momentum – Collisions.
Science Starter! A hockey puck has a mass of kg and strikes the pole of the net at 25 m/s. It bounces off with the same speed but in the opposite.
Momentum and Collisions. Conservation of Momentum.
Goal: To understand momentum
Impulse and Momentum Dr P Ramalingam October 13, 2007.
Conservation of Momentum. For a collision occurring between two objects in an isolated system, the total momentum of the two objects before the collision.
Momentum and Impulse.
Impulse and Momentum Questions
Momentum, impulse, and collisions
Momentum Chapter 2 Section 3 Notes. Imagine This… Imagine a smart car and a dump truck traveling with the same velocity. If both drivers applied the.
Learning Objective › Describe the relationship between changes in mass and velocity to an object’s momentum › Process Skill: scientific writing Success.

Conservation of Momentum and Collision
Conservation of Momentum It’s the Law! Momentum is neither created nor destroyed, only transferred from one object to another OR The total momentum of.
Warm up A 3.00 kg crate slides down a 7 m ramp. The height of the ramp is 5 m off the ground. The velocity of the crate at the bottom of the ramp is 5.
Collisions. Review Momentum is a quantity of motion. p = mv A change in momentum is called impulse. Impulse = p = m v Impulses are caused by forces.

Momentum & Impulse. What does it mean to say “roll with the punches?” Why is it important to wear a helmet? Is it a good thing that cars basically crumble.
Momentum, Impulse, and Collisions. Momentum (P) A quantity that expresses the motion of a body and its resistance to slowing down. P = mv m = mass (kg)
Elastic Collisions Inelastic Collisions. In a closed system, the total momentum of all objects in the system will remain constant In other words…the.
Conservation of Momentum
Aim: How can we apply conservation of momentum to collisions? Aim: How can we apply conservation of momentum to collisions? Identify conservation laws.
Momentum and Energy in Collisions. A 2kg car moving at 10m/s strikes a 2kg car at rest. They stick together and move to the right at ___________m/s.
Momentum is what Newton called the “quantity of motion” of an object. Momentum.
Find the momentum of a 150 kg object moving to the north at 16.0 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?
