Answer:
There is gravity in space – lots of it. Because gravity is everywhere in space, objects in space are always falling: towards the earth, towards the sun, and towards the galactic center. There are two reasons that objects seem to be floating without gravity in space when they are really falling.
First, space is very large and relatively empty by earth standards. Because space is so large, it takes you from hours to years of falling through space until you actually hit the surface of a planet (assuming you have aimed properly so that you actually do hit), instead of the seconds it takes jumping off a bridge.
The second reason that gravity is not so obvious in space is because objects tend to orbit planets instead of hitting them.
Explanation: hope that helps :)
Answer:
Comets Just kinda do their own thing- I beleive that Comets are usually in orbit Because of the sun-As for space dust- There is no wind or anything in space-its kinda like time stands still-Unless a black hole vibe checks Something-

Explanation:
Michael is looking for examples of energy at the park. He notices a mother pushing her child on a swing. He graphs the number of back-and-forth swings that the child completes each minute. Which of these describes the pattern in the graph?
A.The mother decreased the force of her push on the swing.
B.The potential energy and speed of the swing decreased over time.
C.The energy of the child on the swing changed from kinetic to potential.
D.The kinetic energy of the child on the swing increased over time
Answer:
D.
Explanation:
As you see, the graph INCREASES, which means it goes up. It is not going down, only rising.
If I'm wrong forgive me ;-;
