Explanation:

If you go up in an elevator and it accelerates you can feel the sensation of beeing pressed down. This is due to the law of inertea. Mass tends to not be willing to accelerate, there fore an external force is needed to make it accelerate. You can notice this force yourselve, in an elevator that accelerates!
