Answer:
When two objects interact, each one exerts a force on the other that can cause energy to be transferred to or from the object. For example, when energy is transferred to an Earth-object system as an object is raised, the gravitational field energy of the system increases. This energy is released as the object falls; the mechanism of this release is the gravitational force. Likewise, two magnetic and electrically charged objects interacting at a distance exert forces on each other that can transfer energy between the interacting objects.
Explanation:
Even when an object is sitting still, it has energy stored inside that can be turned into kinetic energy (motion). ... A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest.
I can’t do that you have to!
The lightbulb, the fire, and the Sun all create light from some energy source.
The Moon doesn't create light. The parts of it that the Sun shines on
are visible, the parts of it that the Sun doesn't shine on are not visible.
Just like a rock on the ground at night, the Moon must be illuminated
by a flashlight in order to be seen. The Sun is the flashlight.
Answer:
Explanation:
An object's resistance depends on its form and the substance it is made from. The electrical resistance R of the cylinder, as you might expect, is directly proportional to its length L, similar to a pipe's resistance to fluid flow. The longer the cylinder, the more charges of collisions with its atoms can occur. The bigger the cylinder diameter, the more current it can carry.
