Connected Bodies - The Lift Problem What is the lift problem? The lift problem involves objects (particles) that are directly in contact with each other – typically a person or crate in a lift If i...
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 way. Comm...
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 unbalance...
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 ...
Acceleration due to Gravity What is acceleration due to gravity? If motion is vertical and no other forces are acting on a particle, the acceleration of the particle will be due to gravity Accelera...
