Answer:
There is no experiment to prove that you are in motion
Explanation:
A frame of reference which has constant velocity is known as an inertial frame of reference. Motion is relative. One can detect one's motion only when one observes change in position with respect to a fixed body.
Thus, if you are in a spaceship moving at a constant speed in a straight line and unable to look outside, you would not be able to prove that you are moving. Everything within the spaceship would have same speed. If you will throw any object within the spaceship, then the parameters measured by you would also not show that the spaceship is in motion.
Sir Isaac Newton concluded that two factors—inertia and gravity–combine to keep Earth in orbit around the sun, and the moon in orbit around Earth. Hope this helps!
Answer:
the direction of angular momentum = EAST
Explanation:
given
Direction of position = r = north
Direction of velocity = v = up
angular momentum = L = m(r x v)
where m is the mass, r is the radius, v is the velocity
utilizing the right hand rule, the right finger heading towards the course of position vector and curl them toward direction of velocity, at that point stretch thumb will show the bearing of the angular momentum.
then L = north x up = East
It depends on how hard the ball is one and so if its hard it might put a dent in the wall depending on how the ball is thrown at the wall and how hard the ball is and like any other way or big and small and other ways you have to pay attention on how hard it is, how hard you threw it, and how big it is
