Using air tracks made it possible to assume the absence of friction during motion. Motion sensors were used in monitoring the position of the glider with respect to time and the results recorded by use of the portable data…

All freely falling objects experience a downward acceleration. Using the symbol g to represent such special acceleration, the value increases with decreasing altitude. The value of g is around 9.8 m/sec2 at the earth’s surface. Because friction is neglected and the assumption is made that the free fall is not dependent on altitude over short distances, the motion of the freely falling objects is equal to the motion in a single dimension under constant acceleration thus making it possible to apply constant acceleration equations.
The recorded coefficient r values are both close to 1 indicating that the plotted points are closer to the experimental values. As per the recorded values, the increasing x values had a positive gradient whereas the decreasing x values had a negative gradient. Therefore, it is true that X increases at a constant rate with time, hence equation 1 is justified
The velocity after the bounce was higher because of the impulsive force exerted on the glider at the track’s end. Again, the recorded value of acceleration is reasonable because the velocity is reversed at the track’s end meaning there was a moment when no acceleration is acting on the glider.
In the inclined track, the glider was observed to move under a constant acceleration before or after bouncing and this is in harmony with equation 1 which states distance has a direct proportion to the square of time. The slope of velocity against time line matched the previously calculated acceleration value. The slopes of the velocity time graphs in the inclined track with the six blocks also matched the earlier on calculated acceleration value.
The trend observed in the all the three cases validates the linear motion equations. An analysis of the drawn graph gives acceleration values that are consistent proving that constant acceleration equations can be used in describing linear motion in one

From the results obtained from the data sheet the muzzle velocity is supposed to represent the initial velocity of the yellow plastic projectile. It is evident that the range depends on the initial velocity i.e. The higher the initial
enomenon can be explained from Newton’s second law of motion which states that the acceleration of a body as produced by a net force is directly proportional to the magnitude of the net force, and it occurs in the same direction as the net force and inversely proportional to
and graphs were drawn and analyzed to find the dependence of maximum height reached by a body in projectile on initial velocity and angle of elevation.
According to the fundamental laws of physics, when a body if projected into the air, its trajectory motion in determined by
For symmetric objects the moment of inertia I am given by, where β = dimensionless fraction that lies between 0 and 1. For a rectangular block of dimensions, a × b × c has a moment of inertia for a rotation about an axis normal to a × b face and passing through the center of the object. The moment of inertia is affected by the distribution of mass.
