Motion Graphs Three types of graphs that can represent motion are?displacement-time?graphs,?velocity-time?graphs, and?acceleration-time?graphs Displacement-Time Graph On a?displacement-time graph… ...
Acceleration Acceleration?is defined as the?rate of change of velocity In other words, it describes how much an object's velocity?changes?every?second The equation below is used to calculate the av...
Speed & Velocity Speed The?speed?of an object is the distance it travels every second Speed is a?scalar?quantity This is because it only contains a magnitude (without a direction) The?average s...
Distance & Displacement Distance?is a measure of how far an object travels It is a?scalar?quantity - in other words, the direction is not important The athletes run a total distance of 300 m Co...
Solving Vector Problems In physics, vectors appear in many different topic areas Specifically, vectors are often?combined?and?resolved?to solve problems when considering motion, forces, and momentu...
Combining & Resolving Vectors Vectors?are represented by an arrow The?arrowhead?indicates the?direction?of the vector The?length?of the arrow represents the?magnitude Combining Vectors Vectors ...
Vector & Scalar Quantities A?scalar?is a?quantity?which?only?has a magnitude (size) A?vector?is a quantity which has?both?a?magnitude?and a?direction For example, if a person goes on a hike in ...
Error Bars The uncertainty in a measurement can be shown on a graph as an?error bar This bar is drawn above and below the point (or from side to side) and shows the?uncertainty?in that measurement ...
Uncertainties Precision Precise measurements are ones in which there is?very little spread?about the?mean?value, in other words,?how close?the measured values are?to each other If a measurement is ...
