Physics Newtonian Mechanics Motion in Two and Three Dimensions

	Projectile Motion:
	When a stone is thrown by making some angle with the horizontal line, it follows a parabolic path and come back to the ground. The figure will be as follows. This figure shows different positions of the object thrown. When x_i = 0 and a_x = 0, we find So we can write, t = x/(v_i cos θ_i) For y_i = 0 and a_y = -g we get, Substituting the expression of ‘t’ we obtain This equation is the equation of a parabola, which shows that the path of a projectile is parabolic in nature.
