PPT-Chapter 6 – Linear Momentum and Collision

s Compare the inertia of a semi truck and a roller skate Will the truck always have more inertia than the roller skate Will it always have more momentum than the roller skate WarmUp Estimate the amount of work the engine performed on a 1200kg car as it accelerated at 12 ms. 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?. Chapter 7. 7.1 The Impulse-Momentum Theorem. This section deals with time-varying forces affecting the motion of objects. . The effects of these forces will be discussed using the concepts of . i. mpulse and linear momentum.. Introduction to Momentum. What is Momentum?. The quantity of motion of a moving body. Depends on mass and velocity. Measured by multiplying mass to the velocity. Vector. Measured in kg*m/s or N*s. How is momentum measured?. & 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:. . Momentum. – tendency of objects to keep going in the same direction with the same speed. Depends on mass and velocity. Has direction. The momentum of a ball depends on its mass and velocity. Ball B has more momentum than ball A. 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. Corina. . Bot. , PhD (NJIT, C. 2. PRISM).

Momentum is influenced by. Momentum. – tendency of objects to keep going in the same direction with the same speed. Depends on mass and velocity. Has direction. The momentum of a ball depends on its mass and velocity. Ball B has more momentum than ball A. 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 . rd. Law. Chapter . 6: Momentum. Momentum = “inertia in motion”. Specifically, momentum = mass x velocity. = . m v . . Eg. Just as a truck and a roller skate have different inertia, when they are moving, they (generally) have different momenta. . 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.
