Algorithms related to gravity.

When delta_time is too high or too low, causes unwanted problems, e.g., gravity depending on rendered frames per second. In fact, you should use this to all accelerating forces.

# bad
velocity = velocity + (gravity * delta_time)
position = position + (velocity * delta_time)

# good
velocity = velocity + (gravity * delta_time / 2)
position = position + (velocity * delta_time)
velocity = velocity + (gravity * delta_time / 2)
