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 instigate ( f number, displacement, acceleration) oVelocity is the alike(p) as speed miss for the occurrence 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 outperform traveled split by the total time of Travel. part is the space with a direction from some reference point break is the switch all over of go down 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 coal scuttle point and end point is the same. Velocity rate of assortment in position Average velocity is the modification of position separate by the time interval for that change (dis placement 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 rake 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 divided 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 veloci ty on a position-time graph of accelerated m! otion 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 you want to go about a full essay, order it on our website: OrderEssay.net
