The Principle of Conservation of Linear Momentum The principle of conservation of momentum states that in a closed system, the total momentum before an event is equal to the total momentum after th...
Defining Momentum Linear momentum (p) is defined as the product of mass and velocity Momentum is the product of mass and velocity Momentum is a vector quantity - it has both a magnitu...
Newton's Third Law of Motion Newton’s third law of motion states: Whenever two bodies interact, the forces they exert on each other are equal in size, act in opposite directions, and are of the sam...
Acceleration of Freefall Using Electromagnets & Light Gates Aim of the Investigations The overall aim of these investigations is to calculate the value of the acceleration due to gravity, g The...
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...
