What is projectile ? Explain any three factors that affect a projectile trajectory.
A projectile is any object that is given an initial velocity and then follows a path determined entirely by gravity.
There are following factors that affect projectile trajectory:
1.Angle of projection:Any object when projected at different angles covers different distances.When it is released at the angle of 30 degree,making a parabolic path ,it covers less ditance.When it is released at the angle of 45 degree ,it covers the maximum distance.So the distance covered by an object depend on the angle of release of projectile.
2.Initial velocity :The distance covered by an object depend on the initial velocity of the projectile.If the initial velocity is more the object cover maximum distance.On the other hand,if initial velocity is less, the object cover less distance.
3.Gravity:It is the force of attraction excerted by the earth towards uts centre on a body or an object.The greater the weight of an object ,the greater the influence of gravity upon it.
