2-1 Position, Displacement, and Distance In describing an object’s motion, we should first talk about position – where is the object? A position is a vector because it has both a magnitude and a direction: it is some distance from a zero point (the point we call the origin) in a particular direction. With one-dimensional motion,
Solved Example on Distance Formula. Example 1. Suppose a dog runs from one end of the street to another end of the street and the street is 80.0 meters across. Moreover, the takes 16.0 seconds to cross reach the end of the street. Now, calculate the speed of the dog? Solution:
If an object is undergoing uniform acceleration, we can calculate the distance it covers over an elapsed time period. One simple way to calculate the distance covered is to use the formula for average velocity: v avg = distance or v avg = ∆x time t
know formulae for constant velocity and constant acceleration be able to solve problems on motion with constant velocity and constant acceleration, including problems involving several such stages
In this chapter, we study speed, velocity, and acceleration for motion in one-dimension. One dimensional motion is motion along a straight line, like the motion of a glider on an airtrack.
One way to teach this concept would be to pick an orbital distance from Mars and have the students calculate the distance of the path and the height from the surface both in SI units and in English units.
