Gravity force is making him go down the slide, "When someone sits at the top of a slide, gravity is the constant force that pulls the person directly downward. Without the force of gravity pulling a person, a slide wouldn't work at all".
The car goes over the rock but the gravitational pull is making it stay attach to the floor.
the cars crash and theres and equal reaction , both of the cars take the same damage at the same speed.
When the player hits, spikes, or serves the ball it moves in the direction in which the force has been applied. Hopefully, that direction will be over the net, when spiking or serving, and to the target when bumping. The motion stays at motion.

The soccer ball, when kicked, keeps going forward until friction, a person, or another object like a wall stops it.
