Newton's First Law of Motion Newton's First Law states: A body will remain at rest or move with constant velocity unless acted on by a resultant force The law is used to explain why things move wit...
Free-body Force Diagrams Free body diagrams are useful for modeling the forces that are acting on an object Each force is represented as a?vector?arrow, where each arrow: Is scaled to the?magnitude...
Components of Velocity The trajectory of an object undergoing projectile motion consists of a?vertical?component and a?horizontal?component These need to be evaluated separately Some key ter...
Adding Vectors Vectors can be combined by?adding?or?subtracting?them to produce the resultant vector The resultant vector is sometimes known as the ‘net’ vector (eg. the net force) There are...
Resolving Vectors Vectors?are represented by an arrow The?arrowhead?indicates the?direction?of the vector The?length?of the arrow represents the?magnitude Component?vectors are sometimes drawn with...
Scalars & Vectors 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 th...
Slope & Area of Motion Graphs Slope & Area of Motion Graphs Three types of graph that are used to represent motion are?displacement-time?graphs,?velocity-time?graphs and?acceleration-time?g...
Motion Graphs Three types of graph that are used to represent motion are?displacement-time?graphs,?velocity-time?graphs and?acceleration-time?graphs Graphs are named 'y-axis - x-axis', so 'displace...
Equations of Motion The kinematic equations of motion are a set of four equations which can describe any object moving with?constant?acceleration They are often referred to as the 'suvat' equations...
