Discuss the factors affecting projectile's trajectory. |
|
Answer» The following factors affect the trajectory: (a) Angle of projection: When the angle of projection is 150, the maximum horizontal distance is achieved. (b) Initial velocity: The horizontal range also depends on the amount of initial velocity. Greater the initial velocity applied on projectile at the time of release, greater horizontal distance is achieved. (c) Gravity: particularly in throwing events. when an object is thrown in air it is left to fall freely under gravitational force. At the surface of the earth its value is 9.8 metres. Its value changes at different places. At high altitude its value decreases and results in better distance in jumping. (d) Air resistance: Air resistance plays an important role in many sports in which balls or other objects are thrown in air. The speed slows down by air resistance. If the surface of projectile is rough, it will increase friction and will certainly affect the horizontal distance. |
