Electromagnetic waves are produced by the acceleration of an electric charge. Electromagnetic waves have the same speed in a vacuum (or space). They can slow down and change direction.


You can kick a soccer ball (football) in outspace and it will never slow down.


There is no friction in space to slow them down.


Reverse thrusters. They create an opposite force to the shuttles movement, to slow it down. (I think)


No and yes. All objects in space move, but the gravity of the sun and the planets slow down a spacecraft or other object if they get too close.


No!! time can never slow down


If it is facing in the opposite direction of travel it will slow down.


Well, to be honest, electromagnetic wave itself is never slowed down by anything and travels uniformly at the speed of light, c. However, when you look at macroscopic level, it is possible to slow down a combination of many many electromagnetic waves if they travel though a dense medium. The denser the medium, the more 'radiation' is slowed down. So slowing down process occurs when 'radiation' travels from less dense to more dense medium (the closed atoms are packed together, the more they absorb and reemit electromagnetic waves).


No it never dose because it depends what computer you have but this is a list that the computers it slows down slow down dell apple ( slow in the first place) non slow acer ( only)


If you threw a ball in space, it would keep going until the gravity of another body interacted on it. In space, there is no air to slow down the ball, so there is no friction.


Space bcause theres no air resistance to slow down the object in space.


They slow down by firing their engines retrograde(opposite to direction of movement). If the orbit isn't particularly high above atmosphere, it is also possible to slow down due to friction.


Friction and magnetic influences will be external forces that can slow a spaceship down. If we want a controlled slowing down of a ship, we would use reverse thrust. Space is not a perfect vacuum. It is a good one, but not perfect. Movement requires exertion on something.


It can slow your computer down a little but with most computers today you'd never notice.


Drag from air is the main thing that slows down the space shuttle on reentry.

Slow down and leave more space between you and the vehicle in front of you.


Common sense tells you when kids are near the road you slow down. Never know when one will run in front of your car.


Satellites are in the vacuum of space because if they were in the atmosphere, air resistance would slow them down and they would fall to the ground.


Because there is no air in space, there is no friction to slow said object down.


Never it wont even slow down dont Worry!!!


No. There is no atmosphere in outer space. So there would be less resistance to slow the ball down. Not so. There is no resistance in space, it is a vacuum. It would go on forever unless acted upon by an outside force, such as the gravitational pull of another object. Simple Newtonian physics.


Because an electromagnetic wave is a wave that doesn't oscillate matter, rather it oscillates between electric and magnetic fields, a phenomenon that requires no matter. In fact, the only thing that matter does, with all of its tiny, little electromagnetic fields coming from the atoms inside of it, is slow the wave down.
