What kind of charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge. Negative particles, such as electrons, carry a negative charge when they outnumber the positive particles, such as protons.
Is a negative object attracting a neutral object considered magnetism?
Yes, if a negative object is attracting a neutral object, it is considered to be a form of magnetism. This attraction can be explained by the magnetic field produced by the negative object interacting with the neutral object.
Which particles moves when an object acquires a net positive or negative charge?
Electrons are the particles that move when an object acquires a net positive or negative charge. In the case of a positive charge, electrons are removed from the object, leaving an excess of positive charge. Conversely, in the case of a negative charge, electrons are added to the object, creating an excess of negative charge.
What charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge if it has more negative particles than positive particles. This is because the excess negative particles result in an overall negative charge.
Do positive and neutral attract each other?
In the context of physics, positive and neutral particles do not attract each other. Positive and neutral particles do not have opposite charges, so they do not exhibit electrostatic attraction. However, positive and neutral particles can interact through other forces, such as gravity or the strong nuclear force.
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
You can use positive acceleration due to gravity when an object is moving in the direction of the gravitational force, like when it is falling towards the ground. Negative acceleration due to gravity is used when an object is moving opposite to the direction of the gravitational force, like when it is moving upwards against gravity.
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
Why it is taken as negative when an object is thrown upwards against gravitation?
When an object is thrown upwards against gravity, it is viewed as negative because it goes against the natural path of falling due to gravity. It requires energy input to overcome gravity, which is why it is seen as a negative action. Objects thrown upwards will eventually slow down and fall back to the ground due to the force of gravity acting on them.
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.
What does a negative force mean when calculating the electrostatic force between 2 charges?
A negative force indicates an attractive force between the charges, pulling them towards each other. In the context of electrostatic forces, negative forces typically arise when the charges have opposite signs (one positive and one negative), resulting in an attractive interaction.
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 is true about the number of positive and negative charges in a charged object?
A charged object can have an unequal number of positive and negative charges, resulting in a net charge. An object with more positive charges than negative charges will have a positive net charge, and vice versa for negative charges.
When there is an equal amount of positive and negative charges on an object what is the net charge of the object?
The net charge of an object with equal amounts of positive and negative charges is zero. Positive and negative charges cancel each other out, resulting in no overall charge on the object.
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.
Is static electricity negative or positive?
Static electricity can be either positive or negative, depending on the excess or deficiency of electrons on an object. If an object has an excess of electrons, it will have a negative static charge, and if it has a deficiency of electrons, it will have a positive static charge.
