How are friction and force alike?
Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. Both friction and force are vector quantities, meaning they have magnitude and direction. They both can cause objects to accelerate or decelerate depending on their direction and magnitude.
Does friction affect speed or velocity?
Friction can affect an object's speed by reducing it over time, as it acts in the opposite direction to the object's motion. However, friction does not directly affect an object's velocity which is a vector quantity that includes both speed and direction.
What is the reverse process of vectors addition?
reverse process of vector addition is vector resolution.
Rolling friction always reduce the net force acting against an object's motion to zero?
Rolling friction does not reduce the net force acting against an object's motion to zero. Rolling friction is a resistive force that opposes the motion of an object moving along a surface, but it does not completely eliminate the net force. The net force is the vector sum of all forces acting on the object, including rolling friction.
If a vector quantity is divided by its magnitude the vector obtained is called?
The vector obtained by dividing a vector by its magnitude is called a unit vector. Unit vectors have a magnitude of 1 and represent only the direction of the original 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).
Why a force acting on a body is called a sliding vector?
A force acting on a body is not typically called a "sliding vector." The term "sliding vector" may refer to a force vector that is parallel to a surface, which could cause the body to slide if it overcomes static friction. The force could also be called a frictional force if it opposes the relative motion of the body.
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.
