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 a forc...
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 in a ...
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, unless a...
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 acting ...
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 to be a...
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 follows ...
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 direction...
Horizontal & Vertical Components What is a projectile? A projectile is a particle moving freely, under gravity, in a two-dimensional plane Examples of projectile motion include Sports such as b...
suvat in 2D What are the 2D/vector suvat formulae? Given that?acceleration?is?constant,?four of the five suvat formulae can be used with vector The final formula ?can not be written in vector form ...
