Why is it difficult to walk on a slippery road?
It is difficult to walk on a slippery road because the friction between your shoes and the road is compromised. When you stand, its not so much an issue, as most or all of the force vector from your body is pointing down. When you walk, however, there is a horizontal component of the force vector, which is what is accelerating you in a horizontal direction. Since the road is slippery, the coefficient of friction between your shoes and the road is less, causing the tendency to slip or fall.
What is the sum of two vectors A.addition vector B.distance vector C.resultant vector D.displacement vector?
That is usually called the resultant vector.
120 meters northeast vector or scalar?
It is a displacement vector.
Why is Vector resolution the opposite of vector addition?
Vector addition derives a new vector from two or more vectors, and vector resolution is breaking a vector down into its two or more components.
How can a null vector be a vector if there is no direction?
It has magnitude 0 and a direction and obeys vector laws, so is a vector
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.
What is the net force of gravity tension friction and air tension?
The net force refers to the vector sum of the individual forces.
How do you work out the force of an object?
mass of object*acceleration (usually due to gravity-9.8m/s^2)*mu (friction constant for surface) if the object is on a slope, you would multiply the force by the sine of the angle the normal force vector makes with the acceleration vector...
How can you move something further without changing the amount of fource you use?
Reduce friction. Push it down hill. Change the vector (the angle that you shot a gun).
Is friction useful for ships?
Yes and no. In order to go faster, a ship must reduce its air and water friction as much as possible, as friction force acts in the opposite direction as motion, ie slows the object down. However, it is friction that allows the propulsion system to 'push' the ship forward. This deals more with viscosity, which is *like* the friction of a liquid. In sailboats, it is the friction with the air that propels the ship.Because friction is related to the area of contact and the vector of the velocity, it is ideal to have the least amount of surface area facing to the direction of motion, which is why most ships have a Vshape in the front.
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.

What is null vector?
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
How many types of friction is there?
In total there are 4 distinct forces: The electromagnetic force, the weak nuclear force, strong nuclear force, and gravitation. Recently, the electromagnetic force and the weak force has been combined into the electroweak force. Physicists are aiming to "unify" the other two forces like this. Answer2: Forces are the first derivative of energy. Energy is a Quaternion quantity having a scalar/Boson S part and a vector/Fermion V part or a Boson part and a Fermion part. The energy is W = S + V = [s,V] The forces is the first derivative Force F = [d/dr,Del] [s,V] = [ds/dr -Del.V, dV/dr + Del s + DelxV] There are Five Forces; 1. The Centripetal scalar force: ds/dr 2. The Centrifugal scalar force: -Del.V 3. The Tangent vector force: dV/dr 4. The Gradient vector force: Del s 5. The Curl vector force: DelxV For example the five forces of Gravity Forces are: W = -mGM/r + cP = -vh'/r + cP where the vector force is the Momentum energy cmV=cP, the "Dark Energy"! F= [d/dr,Del] [-vh'/r, cP] = [vp/r -cDel.P, cdP/dr - Del vh'/r + cDelxP] F = [vp/r - cp/r cos(P), -cp/r 1P + vp/r 1R + cp/r sin(P) 1RxP] 1. centripetal force: vp/r this is the gravitational attraction force. 2. centrifugal force: -cDel.P= -cp/r cos(P) this is the "Cosmos Divergence" force. 3. tangent vector: cdP/dr = cdP/cdt = dP/dt = mdV/dt 4. Gradient vector: Del -mGM/r = mGM R/r3 = mGM/r2 1R = vp/r 1R 5. Curl Vector: cDelxP = cp/r sin(P) 1RxP this is the circulation/Transverse vector. At the Boundary/Stationary 0=F Condition there are only 4 forces, the Curl is zero, 0=DelxV and Newton's Equal and Opposite forces is true.
What is the angle between vector a and vector b when mode of vector a plus vector b is equal to mode of vector a minus vector b?
90 degrees
What is the sum of two vectors A.addition vector B.distance vector C.resultant vector D.displacement vector?
That is usually called the resultant vector.
Is vector A parallel vector B given that vector A is equal to the zero vector and vector B is equal to the zero vector?
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
