Why did it take so long to discover the theory of relativity?Why didnt Newton fi gure it out?

Physics Projectile Motion New equa2ions R(θ ) = Vo sinθ2)/g h= Vo^2 sin^2( θ ) / 2θ) 2 t= Vi ± √ −2gd+Vo / g Describe motion of object in 2 dimensions Ball is in free fall vertically and moves at a constant speed horizontally Force is in opposite direction to ball’s velocity vector and is proportional to the velocity at relatively low speeds Keep it simple by considering motion close to the surface of the earth for the time being Neglect air resistance to make it simpler An object falling is in free fall vertically and moves at a constant speed horizontally What happens when we add air resistance Adds a new force on the ball The force is in the opposite direction to the ball’s velocity vector and is proportional to the velo
