Forces
Rule: When naming a force, you must describe the object giving the force and the object receiving the force. Original statement: Force an object to accelerate, a force needs to be applied. Second statement: In order for an object to accelerate, an unequal force needs to be applied. If an object is either moving in constant motion or is not moving at all, then the force diagram is 2 equivalent vectors with force earth pointing down and force normal (ground, floor) is pointing perpendicular from the plane. If the object is accelerating, then there is an odd number of forces (ex. 2 equal forces and a third force) or a pair of forces is unequal. CORRECTIONS: (UNIT 3 TEST) *Do not forget fence method! example: 5secs in motion= 6 dots and 5 vectors *Acc vectors are placed on the same dot *Dots on motion map can equal more than 1 unit of time. It can be each dot equals 2 secs too * Use "midpoint method"(the notes are in notebook!) on curved X vs T graph to find instan
