Mass attracts light, just as if light were composed of particles that have mass.
The effect is relatively small. So in order to see it happen, you have to catch light that has passed close to an enormous mass.
This theory was checked by observing the light of a star that appeared near the sun during a solar eclipse.
(It had to be done during an eclipse, when the sun was blocked out by the moon. During normal conditions, with the sun unobstructed and blasting away, it would be impossible to see the star.)
Sure enough, the star appeared slightly too FAR from the sun, because its light bent TOWARD the sun on the way by.
No, not all force fields can attract and repel. Some force fields, like magnetic fields, can both attract and repel objects with opposite magnetic polarity, while others, like gravitational fields, only attract objects and cannot repel them.
In the context of physics, yes. In this context, "repel" refers to two objects that push against each other, while "attract" refers to two objects that pull towards each other.
attract
The opposite of attract when referring to a magnet is repel.
Same poles attract where as opposite poles repel. N-N= repel N-S=attract S-N=attract S-S=repel
Electromagnets can attract or repel nearby magnets depending on their polarity. When an electromagnet is turned on, it creates a magnetic field which can influence the alignment of nearby magnets and cause them to move or align according to the field.
they repel. opposites attract!
A positive charge will attract a nearby negatively charged particle.Oppositely charged particles attract each other while ones with the same charge repel each other.
repel
They repel.
I believe it would be Attract depending on how you use Repel.
All of the metals attract and repel, but if a: negative and positive come together= attract positve and a negative come together= attract negative and negative come together= repel positive and positive come together= repel
attract
they will definatly attract
If charges are alike, they repel. If charges are opposite, they attract.
Repel
Repel.
