Two Examples are: Ex.1, Objects with greater mass have a stronger force of gravity between them. Ex.2Object that are closer together have a stronger force of gravity between them.
According to a research Newton's law states that strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.
What are the major factors that affect the strength of gravity?
Yeah! Can you please give us two examples after?
Magnetism is the force exerted by magnets when they attract or repel each other.Magnetism is caused by motion of electric charges.Every substance is made up of tiny units called atoms.
Electromagnetic has four main factors that affect the strength of an electromagnetic are the loop count, the current, the wire size, and the presence of an iron core.
What about Magnetism?
Friction is the resistance that one surface or object encounter when moving over another.
What about Magnetic field?
First lets talk about Poles.The ends of a magnet are called its poles.One end is called north pole, the other is called south pole.If you line up two magnets so that the south pole of one faces the north pole of the other, the magnet will pull up toward each other.This is called attraction.
Examples of friction: Rubbing hand,sliding,walking.
And what about poles?
The magnetic field is the area around a magnet that has magnet force.All magnets have north and south pole.Opposite poles are attracted to each other,while the same poles repel each other.When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction.
