If it did, nobody would ever deuce their shorts.
there is a type of device on the train of the rollercoaster that is known as the "chain dog". the "chain dog" grabs the hill so it doesn't roll backwards, but it still allows the train to go upwards by the pulling motion of the chain (note: the bolded "chain" is not the chain dog, the chain dog holds while the regular chain pulls)
gravity - velocity - windage - obstructions
Both electromagnetic waves and gravity waves can travel through empty space. Gravity waves travel through matter as well; some electromagnetic waves may travel through some types of matter.
Electromagnetic waves.
Gravity affects the bounce of a basketball because if there is gravity, the basketball will come back down after it bounces. But if there is no gravity, the basketball will bounce and travel indefinitely upwards and never come back down until a gravitational force pulls the basketball towards it.
There is a little something called gravity that stops them moving backwards... it is a physical impossibility
The wind travel by gravity.
Gravity waves travel as small distortions in space and time.
Gravity wave do, so yes.
Space shuttles must travel at 11km/s so that they can escape the force of gravity. the force of gravity is approximately 9.81. If you don't travel at a greater speed than the force of gravity, the rocket will not launch.
If the cycle has a fixed wheel with no release ratchet then it will go in reverse when you pedal backwards.
Backwards to see
gravity makes a rubber band travel
No.
You cannot travel backwards in time
Yes, sound is a longitudinal wave, transverse waves could not travel on the surface without gravity.
C To expound, gravity and light travel at the same speed. * It is a fundamental fact of nature that nothing can travel faster than light, but matter slows light while gravity is not slowed or screened by anything. So light and gravity only travel at the same speed in the vacuum of space away from any mass.
