@getjonwithit It’s also worth nothing that anything that changes direction can only do so by having a non-zero net force applied to it. If a force is applied to something, it accelerates. So as you rotate, you cannot be in an inertial frame due to the acceleration involved.
@getjonwithit 4/3 earth) with a stone in your hand and let it go. If you were in an inertial frame of reference, the stone would not move when you let it go - it would just float next to you. But since it falls/accelerates downwards, our FoR is not inertial.
@getjonwithit 3/3 of 9.81 meters per second per second. The only time you are not accelerating while on earth is when you are in free fall. To recap, standing on earth we are NOT in an inertial frame of reference. To prove this, stand still (or move at a constant velocity on or very close to

@getjonwithit 2/3 you are not in an inertial frame of reference. Recall that gravity is not a force - it is an interaction with curved spacetime. Since it not a force, there is nothing pulling or pushing you down towards the earth. This means that we ARE being accelerated upwards at a rate of
@Alphafox78 @greg16676935420 Have you tried picking yourself up by your own belt without any external non-net zero vertical forces (in the “up direction” in play? It doesn’t work, people.
@ClipCentraI At fault is the driver of the BMW X5 who entered the intersection when it was no clear to do so, despite the green light he or she was facing.
Canada's top court has delivered a highly anticipated judgment, writing in a majority opinion that Ottawa's Impact Assessment Act (IAA), formerly Bill C-69, is largely unconstitutional. So...
