How is discharging in a positive object different in a negative object?
The direction of the flow of electric current. In a positive object, electrons flow to it because it has an abscence of negative charge (aka electrons). In a negative object, it has an abundance of negative charge (electrons) so electrons flow away from it.
What charge does an object have if it has more negative particles than positive particles?
negative
Is a negative object attracting a neutral object considered magnetism?
"Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces.
Do positive and neutral attract each other?
both positive and negative objects attract to neutral object so yes positive and neutral will attract each other.
What are the two like charges?
a positive and a positive or a negative and a negative. Object with the same charge. Like charges repel each other.
What does a negative force mean when calculating the electrostatic force between 2 charges?
An object wont have a force, it will have a force acting on it. If a force acting on an object is negative then that simply means that the objects is in the opposite directon than the defined positive. Eg. An object hitting the ground will exert a force on the ground (F=ma) if we say that up is positive then the force is going to be negative (Acceleration due to gravity will be negative). So the force is not "negative" just opposite to the positive direction. Hope that helps.
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
How can an object have a neutral charge if part of the object has a positive and a negative charge?
If the positive and negative charges are equal, then the object has a 'net' neutral charge.
Force that pulls object to the ground?
GRAVITY
How does force and gravity effect a falling object?
Gravity is a force that accelerates the falling object towards the ground.
Does gravity do positive or negative work on falling objectexplain?
It does positive work. There's 2 ways to look at this: 1) This one's a chemistry way. When work is done on a system by the surroundings, the work is positive. When the system itself is doing work on the surroundings, this is negative work. Just think of it in terms of the system. It gains energy when something does work to it and loses energy when it works on something else. Based on this, do you think it's positive or negative work? 2) This one's a physics way. W = Fd cos (theta). In this equation, W = work, F = a force, d = displacement, and theta = angle between the force and the displacement. So, let's take the example of a falling object. As it falls, the force of gravity is exerting a force towards the ground. The object is moving towards the ground also. Since both the directions are the same, theta is 0 and work is + (cos of angle 0 is +1). When the object is moving upward while gravity is acting on it, exerting a downward force, the angle between them is 180 degrees. At 180 degrees, cos is -1. Work done by gravity is negative in this case. Either ways, positive work is being done by gravity on the falling object.
When is acceleration due to gravity positive and when is it negative?
Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
What often happens when you rub one object with another object?
it depends on the charge...if it is positive on a negative they create static if it is positive on a positive or a negative on a negative...nothingAnother view:The friction develops heat.
Is there any negative charge on a positive charged object?
Any "object" larger than elementary particles consists of positive and negative charges. If your object has a negative charge, it simply has more particles with a negative charge than particles with a positive charge.
Is an object without a charge repelled by both positive and negative charges?
Positive and negative charges would have not effect on an object without charge.
Is an object's net charge positive or negative if it loses electrons?
positive
How is discharging in a positive object different in a negative object?
The direction of the flow of electric current. In a positive object, electrons flow to it because it has an abscence of negative charge (aka electrons). In a negative object, it has an abundance of negative charge (electrons) so electrons flow away from it.
