Newton's Three Laws of Motion Newton’s First Law: A body will remain at rest or move with constant velocity unless acted on by a resultant force Worked Example If there are no external forces actin...
Force & Acceleration As stated on the previous page, Newton's Second Law of Motion tells us that objects will accelerate if there is a resultant force acting upon them This acceleration will be...
What is 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 greater the mass of a body, the smaller the ...
Projectile Motion 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 terms to know, ...
Acceleration of Free Fall Experiment A common experiment to determine acceleration of a falling object which can be carried out in the lab Apparatus Metre rule, ball bearing, electromagnet, electro...
Solving Problems with Kinematic Equations Step 1: Write out the variables that are given in the question, both known and unknown, and use the context of the question to deduce any quantities that a...
Deriving Kinematic Equations of Motion The kinematic equations of motion are a set of four equations which can describe any object moving with constant acceleration They relate the five variables: ...
Gradient of a Velocity-Time Graph Acceleration is any change in the velocity of an object in a given time As velocity is a vector quantity, this means that if the speed of an object changes, or its...
Gradient of a Displacement-Time Graph Displacement-time graphs show the changing position of an object in motion They also show whether an object is moving forwards (positive displacement) or backw...
