Coefficient of Friction What is friction? Friction is a?force?between a surface and an object that acts to resist motion of the object across the surface On a horizontal surface with no forces acti...
Resolving Forces If a single force is applied at an angle to the?direction of motion?it will need to be?resolved?into?components?of the force that act?perpendicular?to each other. Why resolve a for...
Connected Bodies - Pulleys What is a pulley (or peg)? A?pulley?is a wheel like device that rotates as a string passes over it allowing motion of any particles attached to the string The term?‘strin...
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 ...
