FORCES
Sir Issac Newton summarized the effects of force in three basic laws.
First law : Any body at rest will remain at res and body in motion will move uniformly in a straight line unless acted upon by a force. (equilibrium)
Second law : The time rate of change of momentum is equal to the force producing it, and the change takes place in the direction in which the force is acting. (F = ma)
Third law : For every force of action, there is a reaction that is equal in magnitude, opposite in direction, and has the same line of action. (Basic concept of force)
CHARACTERISTICS OF A FORCE
1.Point of application
2.Magnitude
3.Direction
RESOLVING FORCES
-graphical method : just draw the result added force in lines
-analytical method : use trigonometry. (Sin x, cos x, tan x, Pythagorean theorem pythagoras)
