That simply means that the direction is relevant. Consider the following case:
a) Two people pull a heavy item. Both pull in the same direction, with the same force. Together, they can move it more easily than if any one pulls alone.
b) The same people pull in opposite directions. The forces cancel one another (totally - or partially, if the magnitude of the force is not the same). It is unlikely that they will budge the item in this case.
In this example, the direction at which they pull makes a big difference!
What else can I help you with?
What cannot be a scalar quantity?
A scalar quantity is something that only has magnitude and no direction. Any physical quantity that has both magnitude and direction, such as velocity or force, cannot be a scalar quantity.
Is workdone is scalar or vector?
Work done is a scalar quantity. It is defined as the product of force and distance in the direction of the force, and does not have a direction associated with it.
Why is force a scalar quantity?
Force is not a SCALAR because it always has a DIRECTION, making it a VECTOR. A SCALAR quantity is a one-dimensional physical quantity, i.e. one that can be described by a single real number.
What is the definition of force as a vector and how does it differ from force as a scalar quantity?
Force as a vector is a physical quantity that has both magnitude and direction. It is represented by an arrow indicating the direction of the force and its strength. On the other hand, force as a scalar quantity only has magnitude and no specific direction. This means that scalar force only represents the amount of force without specifying where it is applied.
Are force and acceleration scalar quantities?
No. Force and acceleration are vector quantities.
What is the scalar product of the force action on an object and the displacement caused by that force?
Work is the scalar product of the force acting on an object and the displacement caused by that force. In order for work to be done, the object must be moved in the direction of the force.
Is force scalar quantity?
No, it's a vector.
Is force a scalar or vector quantityhttp?
Both! Force is a quaternion quantity, the sum of a scalar force and a vector force. For example there are two gravitational forces, the scalar force Fs= - GmM d/dr 1/r = GmM/r^2 and the vector force Fv= Del -GmM/r = GmM R/r^3.
Is electromotive force a scalar quantity?
No, electromotive force (emf) is not a scalar quantity. It is a vector quantity that represents the driving force that pushes charges through a circuit. It has both magnitude and direction, and is measured in volts.
Is pressure scalar or vector quantity?
Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
What are the five different forces?
The five different forces are the derivatives of the Quaternion Energy E=Es + Ev=[Es,Ev] where Es is the Scalar Energy and Ev the vector Energy. Force = XE = [d/dr,Del][Es,Ev] = [dEs/dr -Del . Ev, dEv/dr + Del Es + DelxEv] dEs/dr the scalar derivative of the Scalar Energy, the Scalar Centripetal Force Del.Ev the Divergence of the Vector Energy, the Scalar Centrifugal Force dEv/dr the scalar derivative of the Vector Energy, the Vector Tangent Force Del Es the vector Derivative of the Scalar Energy, the Vector Gradient Force DelxEv the Curl of the Vector Energy, the Vector Circulation Force.
Why is force not a scaler quantity?
Force is not a scalar quantity because it has both magnitude and direction. Scalar quantities only have magnitude, while vector quantities like force also have a specified direction in addition to size. This directional component of force is what distinguishes it as a vector quantity.
