Mass, Weight & Gravitational Field Strength Mass Mass is the measure of the amount of matter in an object Consequently, this is the property of an object that resists change in motion The great...
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...
