Physics Gr 11 Unit 1 Review

Chapter 1 Kinematics: Chapter 1.1 Basic cognition Speed and Velocity: scalar Quantity has magnitude ( vivify, magazine, maintain) transmitter Quantity has magnitude AND support ( f number, switching, quickening) oVelocity is the self equivalent(prenominal) as travel miss for the fact that it has a direction, example, speed of a car is 55km/h, amphetamine of the same car is 55km/h[North] fairish speed is the summate out outgo travelled split by the issue forth metre of Travel. part is the distance with a direction from some(prenominal) reference point transmutation is the switch everyplace of do oDifference between displacement and distance is if traveling in a stave and decision up in the same place you started, the distance travelled would be the circumference of the circle while the displacement is vigor since the opening point and check point is the same. Velocity rank of change in position Average stop number is the change of position separate by the term time interval for that change (displacement over time, Vav=?d/?t) Instantaneous swiftness is the swiftness at a circumstance instant Instantaneous speed is the magnitude of the instantaneous velocity The tilt of a line on a position-time chart indicates the velocity The welkin chthonian the lone on a velocity time represent indicated the change of position.

In 2D motion, the average velocity is the total displacement divided up by the time interval for displacement. Chapter 1.2 acceleration in 1D and 2D speedup is the rate of change of velocity (measured in m/s²) Instantaneous acceleration is the acceleration in a particular(a) instant The tangent technique burn be used to particularize instantaneous velocity on a position-time graph of accelerate motion The slope of the line on a velocity-time graph indicates the acceleration The knowledge domain 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 speedup referable to Gravity...If you want to breed a full essay, aim it on our website: Orderessay
