-- the charge on either or both objects could increase
-- the distance between the objects could decrease
(Your teacher doesn't need the answer. The question was assigned to you so that
you'd learn how to figure out an answer that you don't know, and when you found it,
you'd know something that you didn't know before. Now all you have to turn in for
homework is some words that you don't understand and the teacher doesn't need.
Nice work.)
Lightning occurs when there is a large difference in charge between the ground and storm-clouds. This acts similar to a huge capacitor. When the potential difference becomes large enough, lightning arcs from the ground to the clouds. So there is already an electric field in the air under a storm-cloud. A magnetic field can produce its own electric field. The addition of these two electric fields may increase the potential difference enough to cause a lightning arc is the superimposed E-field is large enough.
Negatively charged objects can attract positively charged objects, repel other negatively charged objects, and cause static electricity buildup.
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
Friction can cause objects to slow down or stop when they are sliding against each other. It can also generate heat as a result of the contact between surfaces. Furthermore, friction can cause wear and tear on the surfaces of objects, leading to their deterioration over time.
No, electric shocks typically do not cause bruising. They can cause burns or tissue damage at the site of contact, but bruising is not a common symptom. If you have concerns about an electric shock injury, it's important to seek medical attention.
When electrons move from one object to another, they can cause an imbalance in the charge distribution of those objects. This can create areas of excess positive and negative charges on the objects, leading to the buildup of electric charge. The movement of electrons helps to create an electric field that can generate more charge separation between the objects.
Static charge refers to an imbalance of electric charge on an object, whereas electric force is the force that exists between two charged objects. Charged objects with opposite charges attract each other due to electric force, while objects with like charges repel each other. Static charge can create electric forces that cause objects to attract or repel each other.
Gravitational energy can increase with an increase in the mass of an object, as more mass means more gravitational force. Additionally, gravitational energy can increase with a decrease in the distance between two objects, as the force of gravity gets stronger as the distance between objects decreases.
It causes a proportional increase in current.
No.
Increasing one object's mass would increase the gravitational force between the two objects. This would cause a greater attraction between the objects, resulting in an increase in the force pulling them towards each other.
Wet or icy conditions can cause surfaces to become more slippery, increasing friction between objects. Additionally, strong winds or storm conditions can generate forces that increase the friction on surfaces.
Electric forces can cause objects to either repel or attract each other. Objects with like charges (positive-positive or negative-negative) will repel each other, while objects with opposite charges (positive-negative) will attract each other.
The interaction between two objects can involve forces such as gravity, electromagnetism, or contact forces. These forces can cause objects to attract, repel, or cause motion between them. The specific interactions depend on the properties of the objects and the distance between them.
Excess electric charge refers to a situation where an object has more electric charge than it normally carries in a neutral state. This can occur through the transfer of electrons between objects, leading to an imbalance of positive and negative charges. Excess electric charge can cause objects to become negatively or positively charged and can result in electrical discharge if the imbalance is not resolved.
Static electricity can attract objects or cause objects to stick together due to the imbalance of electric charges. However, it does not have the ability to physically move objects on its own.
If one object near another object is increased in mass, the gravitational force between the two objects will increase. This will cause the objects to exert a stronger attraction on each other, leading to a greater gravitational pull between them.
