Physics Gr 11 Unit 1 Review

Chapter 1 Kinematics: Chapter 1.1 Basic Knowledge Speed and Velocity: scalar Quantity has magnitude (speed, time, maintain) Vector Quantity has magnitude AND advocator ( f number, displacement, acceleration) oVelocity is the same(p) as speed miss for the detail that it has a direction, example, speed of a car is 55km/h, velocity of the same car is 55km/h[North] Average speed is the summate out blank space traveled split by the total time of Travel. part is the keep with a direction from some reference point novelty is the switch oer of government agency oDifference between displacement and distance is if traveling in a circle and ending up in the same place you started, the distance traveled would be the circumference of the circle while the displacement is zero since the beginning point and end point is the same. Velocity rate of careen in position Average velocity is the change of position separate by the time musical interval for that change (displacem ent over time, Vav=?d/?t) Instantaneous velocity is the velocity at a circumstance instant Instantaneous speed is the magnitude of the instant(prenominal) velocity The slope of a kris on a position-time chart indicates the velocity The area chthonian the lone on a velocity time represent indicated the change of position. In 2D motion, the average velocity is the total displacement split up by the time interval for displacement. Chapter 1.2 acceleration in 1D and 2D Acceleration is the rate of change of velocity (measured in m/s²) Instantaneous acceleration is the acceleration in a particular instant The tangent technique can be used to determine instantaneous velocity on a position-time graph of accelerated motion The slope of the line on a velocity-time graph indicates the acceleration The area under the line on an acceleration-time graph indicated the change in velocity The change in velocity divided by the time interval is equal to acceleration Chapter 1 .3 Acceleration referable to Gravity...If y! ou want to purport a full essay, order it on our website: OrderCustomPaper.com
