PPT-Conservation of Momentum

Practice Problems 1 Two grocery carts collide a full one with a mass of 35 kg moving East at 2 ms and an empty one with a mass of 10 kg moving West at 3 ms After the collision the full cart is moving .

A sound means . t. o predict behavior of systems for which limited quantitative data are available. Chapter 3, Section 7. Date:. HW: PTG #1-8, pg. 332. Learning Objective:. Explain collisions in terms of Newton’s Laws, momentum, and impulse. Success Criteria:. Define impulse. Explain conservation of momentum. Physics. Problem #1. A 1500 kg car traveling +6 m/s collides with a 2000 kg truck at rest. The vehicles collide, but do not stick together. The car has a velocity of -3 m/s after the collision. What is the velocity of the truck after the collision? . Pg. 222- 227. Momentum & Impulse. The driver of this race car walked away from the car without a scratch. Luck had little to do with this fortunate outcome though – a practical application of Newton’s laws of motion by the engineers who designed the car and its safety equipment protected the driver from injury. & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . Have you ever wondered….

With no external force, momentum doesn’t change. It’s the opposite of the impulse momentum relationship!. Ft = Δmv. Example. Consider a gun being fired.. A gun recoils when it is fired. . Work Energy and Momentum Physics Unit 3 This Slideshow was developed to accompany the textbook OpenStax Physics Available for free at https:// openstaxcollege.org/textbooks/college-physics By OpenStax What is Momentum? Momentum may be defined by its equation: Momentum is a quantity defined as the product of the mass and velocity of an object. Unit of Momentum The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity. Momentum. Measures how hard it is to stop a moving object.. Momentum can be defined as . "mass in motion.". . All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. .
