Scalar Vector Motion Equilibrium
What do you mean by equilibrium? Equilibrium is a state of rest of a body. Equilibrium equations also include the body moving with zero acceleration (uniform velocity) along a straight line. What is motion? When it will occur? Motion is change of position of a body with respect to time. To have a motion in any direction, the body should have an unbalanced force in the same direction. What is scalar? Give some examples Scalar is a physical quantity that contains only magnitude information. E.g. Mass, Time What is vector? Give some examples Vector is a physical quantity that contains both magnitude and direction information. E.g. Weight, Distance
