PPT-Momentum and Impulse Conservation of Momentum

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 . 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.. & 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:. . IMPULSE AND MOMENTUM. I. IMPULSE. A baseball hits a bat.. The velocity of the bat changed. (Vf-Vi). The velocity of the ball changed. (Vf-Vi). Vi. Vf. Vi. Vf. B. NEWTON’S 3. rd. Law. For every action (ball hitting bat), there is an equal and opposite reaction (bat hitting ball).. Have you ever wondered…. How a tae kwon do expert can break a stack of cement blocks?. Why falling on a cement floor hurts more than falling on the grass?. Why a follow through is important in golf, baseball or boxing?. State the principle of conservation of momentum.. Demonstrate the principle of conservation of momentum.. Solve problems about conservation of momentum.. Discuss conservation of momentum in e.g. collisions, spacecraft, aircraft.. Excerpts . from . Chapters 9 and 11. Impulse and Momentum. Newton’s . 2nd. Law of motion can be rewritten by using the definition of . acceleration. as the change in . velocity. over the change in time.. 9. Kinetics. 2. Projekt: Cizí . jazyky v . kinantropologii. - . CZ.1.07/2.2.00/15.0199. Daniel . Jandačka. , PhD.. Impulse of Force. Impulse of force . is the product of the resultant force . Σ. (Linear) Momentum, p. ● . is mass times velocity. . . vector. !. . ● . . (p) = kg m/s. ► . a 1 kg object moving at 1000 m/s has the same momentum as a 1000 kg object moving at 1 m/s (p = 1000 kg m/s). & 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 = 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. … to change equilibrium states!. We have seen that…. …. equilibrium . is a. self-sustained state. ;. We have seen that…. … equilibrium is a self-sustained state;. …. objects in equilibrium . 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 . You can calculate the momentum of a particle and the impulse of a force. The momentum of a body of mass . m. which is moving with velocity . v. is given by . mv. If the mass is in kg and the velocity is in ms. Impulse and momentum. There are many situations in which the force acting on an object is not constant.. The force varies with time. Impulse and momentum. To describe how a . time varying force . affects the motion of an object, we need to use .
