Moments Diagrams When an object is modelled as a particle we do not need to consider the rotation of the object due to forces. When we model an object as a rigid body then we need to consider the r...
Coefficient of Friction - Equilibrium How is friction used when a body is in equilibrium? When a body is in static equilibrium under the action of a number of forces, including friction, the value ...
Coefficient of Friction - Inclined Planes How is the coefficient of friction used in problems involving inclined planes? On an inclined plane the basic principles are the same as for coefficient of...

Coefficient of Friction - F = ma How do we apply Newton’s Second Law (F = ma) in problems involving friction? The coefficient of friction combined with F = ma allows you to determine an object's mo...
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...
