PPT-Linear Momentum

Linear Momentum Momentum is a measure of how hard it is to stop or turn a moving object p m v single particle P Σ p i system of particles Problem How fast must an electron move to have the same momentum as a proton moving at 300 ms. N is the process noise or disturbance at time are IID with 0 is independent of with 0 Linear Quadratic Stochastic Control 52 brPage 3br Control policies statefeedback control 0 N called the control policy at time roughly speaking we choo e Ax where is vector is a linear function of ie By where is then is a linear function of and By BA so matrix multiplication corresponds to composition of linear functions ie linear functions of linear functions of some variables Linear Equations Lots of fun!. Win . valuable prizes!. 1.The reason padded dashboards are used in cars is that they . look nice and feel good. . decrease the impulse in a collision. . increase the force of impact in a collision. . We will now quantify exactly how it hits the fan.. Momentum. Momentum = product of mass X velocity. Symbol for momentum is “p” (don’t ask me why). So, p = . mv. Momentum is also a vector and points in the direction of velocity. 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.. 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?. 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?. Warm-Up. Estimate the amount of work the engine performed on a 1200-kg car as it accelerated at 1.2 m/s. Movement around a fixed point or axis. Spin; somersault . Occurs when a force is applied outside the centre of mass. An off centre force is referred to as an eccentric force.. Examples of a force being applied outside the centre of mass of an object or body to cause rotation. . 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. and . Collisions. Momentum. Impulse. Impulse-Momentum . theorem. Conservation of . linear momentum. Collisions. Momentum. , p. The linear momentum . p. of an object is the product of the object’s mass . 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.. What is Momentum? Unit 8 Section 3 Momentum Momentum is a property of ALL moving objects Momentum is the product of the mass and velocity of an object. Momentum = mass x velocity ( P=M x V) Momentum is labeled as kg x m/s with a direction. 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. .
