When an object has orbital motion its velocity and acceleration are?
Orbital motion occurs whenever an object is moving forward and at the same time is pulled by gravity toward another object. The forward velocity of the object combines with acceleration due to gravity toward the other object.
What keeps the earth from flying into space?
The Short Answer: Earth’s gravity is strong enough to hold onto its atmosphere and keep it from drifting into space.
How do you travel halfway around the world without a plane?
A faster way, where you can travel halfway around the world in less than an hour, with no pesky seats, or even an airplane at all. All you need to do is jump… down. Into that enormous tunnel bored right through the Earth connecting your location with the exact opposite spot on the Earth – your antipode.
Why don’t planes fall off the edge of a flat Earth?
One of the more interesting pieces of evidence came from speaker Darren Nesbit, who referred to the “Pac-Man effect” as the reason why planes don’t fall off the edge of a flat Earth, according to the science news website Physics-Astronomy.org.
What would happen if you jumped into a tunnel from Earth?
A tunnel, dug from one side of the Earth to the other would be, on average, 12,742 km. So it’s a shorter trip, sure, but that’s not the best part. If you jumped into the tunnel, you’d fall down towards the center of the Earth, accelerating constantly, thanks to gravity.
What is the distance around the Earth in kilometers?
The circumference, or distance around the Earth, is approximately 40,075 km, but that depends on where you measure it; around the equator, or from pole to pole. So, to travel overland from one location to its antipode, you’d need to travel 20,037 km. A tunnel, dug from one side of the Earth to the other would be, on average, 12,742 km.
