Projectile motion is a form of motion that moves along a curved path( parabola) caused by gravity.
What is the maximum range for a projectile?
45 degrees
Horizontal and vertical direction have nothing to do with each other when talking about projectile motion. The directions are independent.
Suppose you drop a ball and throw a ball forward from the same height. Which will hit the ground first?
