Impact of Air Resistance on a projectile in motion

Syed Maaz Ali Bukhari Page 2 of 3

Introduction A projectile is any object that has an initial velocity and subsequently travels along a route that is purely dictated by gravitational acceleration. Since the x and y components are parallel to one another and only time (t) connects them, any y component may be ignored when a projectile is launched at an angle of 0*, since a angle of 0* will not create further y values. The linear motion can be utilized since Figure 1. equation The total displacement s of a soccer ball atthe a point along its path. The vector s has components x and y along the horizontal components are parallel. The equation may and vertical axes. Its magnitude is s, and it makes an angle θ with be reduced to since there is no the horizontal. acceleration in the x direction. As the linear equation t has no acceleration in the x direction, range may now be determined on an independent variable of either initial velocity or final velocity, making . Since the components are linear, will also provide a linear value.

Aim To study the projectile motion of a ball launched from a hand-powered launcher at angles of 0,12, 24, 36, 48, and 60 degrees, altering the initial velocity, impacting the range of the projectile launched.

Hypothesis As initial velocity increases, the range will also increase due to the expected linear relationship of

Risk Assessment Identified Risk Multiple balls on the floors are a trip and slip hazard, if someone were to slip on them, they could break bones or cut themselves on surrounding objects. Ball projectile could hit someone

Precautions Balls should be placed on desks in a surrounded container so that they do not roll of the desk, If no one as to roll off the desk, it should be picked up immediately. Stay at a distance of at least 50cm to be safe
