PPT-Fun Side of Mechanics: Momentum (Collision) energy

By Jonathan Recap Last week we talked about countersteering What was countersteering Turn in the other direction in order to complete a turn A while back we mentioned velocity What was . http://. www.aplusphysics.com. /courses/honors/momentum/. collisions.html. Unit #4 Momentum. Objectives and Learning Targets. Define and calculate the momentum of an object.. Determine the impulse given to an object.. . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . Momentum and Impulse. Lecture PowerPoint. Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display.. Collisions. How can we describe the change in velocities of colliding football players, or balls colliding with bats?. Physics 7. th. edition. Classroom Response System Questions. Chapter 7 Impulse and Momentum. Interactive Lecture Questions. . 7.1.1. An astronaut drops a golf ball that is initially at rest from a cliff on the surface of the moon. The ball falls freely under the influence of gravity. Which one of the following statements is true concerning the ball as it falls? Neglect any frictional effects.. (d)define . linear momentum as the product of mass and velocity. (e) define force as rate of change of momentum. (f) recall and solve problems using the relationship F = ma, appreciating. that acceleration and force are always in the same direction. & 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:. . I. . . Collisions. . II. . Work and Energy. Momentum:. an object of mass m, moving with velocity v has a momentum p = m v.. Momentum is an important and useful concept that is used to analyze collisions . . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . mr. taylor. 8.6. Collisions . of. . Point . . Masses . in Two Dimensions. . Boom . Crash. Bang. Smash. Video Example of a Collision. . . 8.6 objectives. - Discuss 2D collisions as an extension of 1D analysis. Notes. Momentum Conservation Principle. One of the most powerful laws in physics is the law of momentum conservation. . For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects . Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. What factors affected how fast objects move after a collision? (Think of your lab). Section 1: Momentum and . Impulse. Linear Momentum:. Momentum is defined as . mass times velocity. .. Momentum is represented by the symbol p, and is a . Momentum and Impulse. Objectives:. 1. Compare the momentum of different moving objects.. 2. Compare the momentum of the same object moving with different velocities.. 3. Identify some examples of change in the momentum of an object..
