How can static electricity build up on an object?
It Rubs off Onto another object.
Which set of conditions must be satisfied in order for an object to move in a circular path at a constant speed?
Well you shall need the initial force which propels the object, and there should be no hindering forces acting on the object when it is in motion. However all these forces will mean nothing without a force 'holding' the object onto the centre of rotation i.e. force of gravity, tensional force e.t.c.
A moving charge that exerts a force onto another moving charge is called what?
power
How can you change an object's mass?
-- glue another piece onto it -- cut a piece off of it -- move it around your laboratory very fast
What is the point at which all the weight of an object seems to act?
An objects weight is evenly distributed around its center of gravity or center of mass. Imagine you attach a string to some random point on an object and then let the object hang while holding onto the string. It happens that the center of gravity of the object will always be directly below the point where the string is attached to the object. In fact, this is a good method by which to manually determine the center of gravity of an object. Another way to think about it is this. If you were to apply a force to an object at some random point, in general, not only would the force cause the object to accelerate but the force would also tend to cause the object to rotate. However if you apply the force at the object's center of mass, the object would not tend to rotate in any way, it would only accelerate in the direction of the force.

What is an gravitational force exerted on an object?
The gravitational force exerted on an object, according to classical mechanics, is the product of the gravitational constant, the object's mass, and the mass of the object exerting the gravitational force divided by the square of the magnitude of the position vector starting from the object exerting the gravitational force and pointing to the object which we are measuring the force exerted onto. And all of this is times the negative of that same position vector.
If the net force on an object is zero is the net torque zero?
Yes. If an object is at rest or in a linear motion state at constant speed, the net force applied onto the object is zero.
Do action and reaction forces cancel each other?
Yes and no. They are equal in size and opposite in direction, but they are NOT exerted onto the same object. Each object exerts exactly one force and each object RECEIVES exactly one force. With only one force being exerted onto each object, there is nothing to be cancelled on each single object. Thus, they do not cancel, they simply exert themselves on different objects.
What allows you to hold things?
The force of your hands holding on two sides of the object you wish to hold. Although the gravitational force that is pulling the object downward is great; the force your hands are pressing onto the sides of the object is a lot greater. You will find that if you don't hold an object as tightly (decrease the force) it may drop. This is because the gravitational force increases.
Can carpet pass an electricity to another object?
Correction* Can carpet pass electricity onto another object? If you mean static electricity then yes, but depending on the charge of the other object.
How many types of symmetry are there?
There are several types of symmetry:rotational symmetry: an object maps exactly onto another if rotated about an axistranslational symmetry: an object maps exactly onto another if moved along a linereflective symmetry: an object maps exactly onto another if reflected along a lineand many combinations of the above, such as helical symmetry where an object maps exactly onto another if moved along a line and rotated about an axis.· Rotoreflection symmetry· Helical symmetry· Non-isometric symmetries· Scale symmetry and fractals
Is friction required to make sound?
No, the only thing required to make an object produce sound is to apply enough sudden force onto a minimally supported object, forcing it to dissipate that force all by itself. To do this the object vibrates, which produces sound.
