losing information  \n When considering force interactions objects can be represented as point particles  \n These point particles should be placed atthe center of mass of the object  \n Force vectors that act upon that objects should be drawn with their tail on that point particle  \n The length of the force vector corresponds to its strength  \n The longer the vector, the greater the force magnitude  \n The below example shows the forces acting on an object when pushed to the right over a rough surface  \nPoint particle representation of the forces actingona moving object  The below example shows an object sitting on a slope in equilibrium  \nYour notes  \n© 2015 − 2024 Save My Exams, Ltd. · Revision Notes, Topic Questions, Past Papers  \nHead to www.savemyexams. com for more

force (depending on your local context either of these could be acceptable)  \nUsing unexpected notation can lead to losing marks so try to be consistent with expected conventions.  \nYour notes  \n©

modeling the forces that are acting on an object  \n Each force is represented as a vector arrow, where each arrow:  \n Is scaled to the magnitude of the force it represents  \n Points in the direction that the force acts  \n Is labelled with the name of the force it represents or an appropriate symbol  \n Free body diagrams can be used:  \n To identify which forces act in which plane  \n To resolve the net force in a particular direction  \n The rules for drawing a free-body diagram are the following:  \n Rule 1: Draw a point in the centre of mass of the body  \n Rule 2: Draw the body free from contact with any other object  \n Rule 3: Draw the forces acting on that body using vectors with correct direction and proportional length  \nFree body diagrams can be used to show the
