how is time, t related to the inclination of the track? Explain why? Time and position of velocity are interrelated to each other and the height and gravitational pull affects the acceleration of a moving and a free falling object. 3. From the data obtained, how would you account the difference between the picket fence’s acceleration and the value of g? The value of the slope of a graph of average velocity versus time will be the acceleration due to gravity of the falling object. ...

Velocity The word, velocity, originates from the Latin word, vēlōcitās, meaning swiftness or speed. Velocity is one of the basic words used in mathematics and physics and forms the basis for the more important formulae used in high level study of these subjects. According to the dictionary, the definition of velocity is the rate of change of position of an object. In simple words, velocity means the distance travelled by an object over some time divided by the time taken by the object...

2: SPEED, VELOCITY AND ACCELERATION 2.1 Distance and Displacement • Distance is the total length covered by a moving object irrespective of the direction of motion, i.e. only the magnitude is of importance. • Displacement is the distance measured in straight line AND in a specific d__________________. Both magnitude and d_________________ are important. Example 1 A car travels 5 km due east and makes a U-turn back to travel a further distance of 3 km. Find (a) the distance covered, (b)...
