What is the magnitude of the net electric force on the charge Q due to the other three charges?
That depends on where the charges are, and the magnitude of the charges. In general, you must calculate the vector for the force due to each individual charge, then add all the vectors together.
What is the force of repulsion acting on each sphere?
What force is acting? Gravity? Electricity? Magnetic repulsion? And what is the mass/charge on each sphere anyway?
When forces are acting upon something motion occurs if?
Assuming this is a vacuum: Motion would occur only if there is no secondly force acting on the object with the same magnitude(strength) but has the opposite direction to the force you're acting upon this object.
What is the magnitude (size) and direction of the cumulative force acting on the car shown in the picture above?
30 N to the right
When two forces are acting in the opposite direction how do you calculate the net force?
gravity

What offsets an action force?
A force of equal magnitude, acting in the opposite direction.
What is the upwars force acting on an object?
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
An object at rest has two forces acting on it. The first force is 315 N acting along the x-axis. What is the MAGNITUDE of the second force?
Magnitude is 315 N. Direction would be opposite the first force, so they cancel out and leave the body at rest.
Define law of transmissibility of forces?
"The condition of equilibrium or motion of a rigid body is remain unchanged, if a force acting on the rigid body is replaced by another force of the same magnitude and same direction but, acting anywhere along the same line of action."
What is the magnitude of the resultant force in Newtons acting on an object that has 2 forces acting in same direction having magnitudes of 15 N and 25 N and a 3rd force acting perpendicular at 30 N?
Add forces 1 and 2 = 40N Magnitude of resultant = root[402+302] = 50N [Also, this is at an angle of 36.9 degrees to the 30N force]
What is the magnitude of the gravitional force acting on an object?
Magnitude is a scientific way of saying size or number. The gravitational force is the force (measured by Newtons (N)) acting on an object. On earth, the gravitational force is 9.81 Newtons, this can be commonly rounded to 9.8 or even 10, depending on the accuracy required. In laymen's terms, the magnitude of the gravitational force is simply the strength of gravity acting on an object.
What is the force of repulsion acting on each sphere?
What force is acting? Gravity? Electricity? Magnetic repulsion? And what is the mass/charge on each sphere anyway?
Any time there is no change in the movement of an object what is true of the force pairs acting on the object?
They are equal in magnitude.

What happens when one object exerts force on another?
Te naswer depends on the direction and magnitude of the force and any other forces acting on the body.
