Connected Bodies - Ropes & Tow Bars What are connected bodies/particles? The phrase connected particles refers to situations where two (or more) bodies (objects) are connected in some wa...
F = ma What is Newton’s First Law of Motion (N1L)? An object at rest will stay at rest, and an object moving with constant velocity will continue to move with constant velocity, unless an un...
Forces in 2D - Vector Notation How are forces and vectors linked? Forces are vectors – they have magnitude and direction. The Magnitude of a force is measured in Newtons and the direction of...
Equilibrium in 2D What does two dimensions (2D) mean in mechanics? In two dimensions, a particle may be considered as existing and being able to move around two-dimensional space rather than...
Equilibrium in 1D What is Newton’s First Law of Motion (N1L)? An object at rest will stay at rest, and an object moving with constant velocity will continue to move with constant velocity, ...
Force Diagrams Why do we need force diagrams? Force diagrams are used to help understand a given scenario and show which forces are acting on which particles and in which direction they are ...
Deriving Projectile Formulae What projectile formulae do I need to be able to derive? In the previous notes the equation of the trajectory of a particle was derived Other equations you need ...
Equation of a Trajectory What is the trajectory of a projectile? The trajectory of a projectile is the path it follows during its motion The modelling assumptions mean it is symmetrical It ...
Using suvat How do I use the suvat equations to solve projectile problems? For projectile motion with acceleration a m s-2 and initial velocity u m s-1 ax = 0, ay = ±g (depending on which di...
