Projectile Motion can be described by the horizontal and vertical components of motion. i.e, If a person throws a ball from any point with any speed (u) with any angle θ (theta), and due to the gravity (g) a downward force is applied on it which is constant (9.8m/s²) then the motion of the ball is called projectile motion, and the max height attained by the ball is denoted by (h). The total distance covered by the ball from initial point to final point is called the Range(R).
Range: To find the range or the distance covered by the object, we need to know the initial speed which is (u) and the angle by which the object is through out where as the g is constant which is 9.8m/s², put these values in formula for the range & Time: To find the time at which the the ball touch the ground, we also need to know that the initial speed and the angle theeta and g is constant & Max Height: To find the maximum height covered by the object is initial speed and the angle
