Magnitudes that have a direction are called vectors. An arrow can be used to represent them.
a vector, which has magnitude and direction.
Three symbols for force used in formulas
A vector can represent the direction and strength of a force.
A vector can represent the direction and strength of a force.
We usually use an arrow to represent a force. It's length is proportional to the magnitude of the force, and it points in the direction the force operates.
which pulley changes the direction of force
A negative direction.
A vector can represent the direction and strength of a force.
A vector can represent the direction and strength of a force.
A vector is a quantity with magnitude and direction. Since force has magnitude and direction, it is a vector
We usually use an arrow to represent a force. It's length is proportional to the magnitude of the force, and it points in the direction the force operates.
which pulley changes the direction of force
A negative direction.
An Arrow can be used to represent a vector by having the direction of the arrow indicate the direction of the vector and the size or length of the arrow represent the size of the vector.
Why do you think that arrows of varying lengths are used to represent forces?
Work = Force x Displacement in the direction of the Force.
Yes, basically. But please note that there is no such thing as the "speed of a force". A force vector describes the magnitude of a force, and its direction. In general, a physical vector - the vectors commonly used in physics - describes the magnitude of something, and its direction.
An Arrow can be used to represent a vector by having the direction of the arrow indicate the direction of the vector and the size or length of the arrow represent the size of the vector.
On a diagram that include light rays, lines with arrows on them to represent the direction of the light rays could be used. Hope that answers your question.
