In which direction does friction act compared o the direction of movement?
In the same direction as the movement
If a force is exerted on an object is it possible for that object to be moving with constant velocity?
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
Does friction affect speed or velocity?
Speed is a scalar (non-directional) representation of velocity. Friction affects the magnitude of both and the direction of velocity.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
State laws of limiting friction?
1. the direction of force of friction is always opposite to the direction of motion.. 2. the magnitude of limiting friction depends upon the nature and state of polish of the two surfaces in contact and acts tangentially to the interface between them.. 3. the magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.. 4. the magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same..

Does friction have anything to do with numbers?
Yes, friction is a force it possesses magnitude and direction. It's magnitude and direction are measured in in Newtons and radians (or other angular measurement) which are written in numbers.No friction is a phenomenon; numbers a human idea. But numbers can be used by humans to express and calculate many things which concern friction.

Is a force of friction a vector or scaler quantity?
Either, or both. Motion can be described in either vector or scalar terms. Speed is a scalar quantity, having only a magnitude. Velocity is a vector quantity, having both magnitude and direction. Acceleration is a vector quantity.
How is an able to maintain a constant speed when friction acts upon it?
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.

How do friction and gravity relate?
The magnitude of friction is proportional to the magnitude of the normal force which is proportional to the magnitude of gravity(The magnitude of the normal force is indirectly proportional to the magnitude of gravity.). The magnitude of the normal force, N, compared to gravity, G, on angle z, is: N=cos(z)*G On a flat surface. N=G The coefficient of friction, whether static or kinetic, f is therefore: N=cos(z)*G*f

What magnitude pushing force is needed to keep a box moving at a constant 8 meter per sec if there is a static friction of 5 lb and kinetic friction of 4 lb?
While the box is moving in a straight line at a constant speed, the push only has to overcome the kinetic friction. Whatever the speed is, and whatever the weight of the box is, 4 pounds of push IN THE DIRECTION THE BOX IS MOVING will keep this one going.
What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
How do you derive banking of road?
If a vehicle is moving on a circular road which is rough and banked also then magnitude of N and direction plus magnitude of friction mainly depends on the speed of the vehicle V-
