ENGR101 Lab 3 Thursday and Friday, Sep 11 th and 12 th Concepts: Writing a simple C++ code from scratch Functions Decision making Some basic physics concepts Consider an object P moving along a straight line from left to right (Figure 1). The position of P at any given time t may be determined by its distance s measured from some convenient fixed reference point O located on the same line. This position is shown as P 1 in Figure 1. At time t+ t the object has moved to point P 2 and its new position measured from point O is s+ s. The change in the object’s position within the time interval t is called the displacement of the object and is shown by s. Figure 1: Object motion along a straight line The average velocity of the object within the time interval t is equal to the object’s displacement divided by the time interval or t s v av Δ Δ = / (1) This implies that if an object moves in constant velocity, that velocity is in fact the same as the average velocity and can be calculated using equation (1).
