What is a force vector of -3 Newtons?
A force vector of -3 Newtons indicates that the force is acting in the opposite direction of the positive direction, with a magnitude of 3 Newtons.
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 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 isCoulomb's law in terms of position vector?
the force of attraction or repulsion = (k*q1*q2*r')/r^3 where r' is the position vector
What best detirmines the net force when more than one force is acting on an object?
You need to get the vector sum. You can do this by resoving all forces into its 3 axis components, adding forces in like axes, and compute the new vector.
Columbs force is vector or not?
Columbs force is a vector and a scalar it is a Quaternion, Coulombs' Force is the derivative of the energy E= -e^2zc/4pi r. The derivative is consists of a scalr and a vector. XE= [d/dr, Del] [-e^2/zc/4 pi r, 0] = -e^2zc/4pi (d/dr(1/r) + Del 1/r) XE = e^2zc/4pi r^2 (1 + R/r) where R/r is the unit vector. Columb's Force is a quaternion involving a scalar force e^2zc/4pi r^2 and a radial vector force, e^2zcR/4pi r^3.
What is the magnitude of a vector 3V?
3 times the magnitude of the vector V - which is not known.3 times the magnitude of the vector V - which is not known.3 times the magnitude of the vector V - which is not known.3 times the magnitude of the vector V - which is not known.
What is total force in physics?
Total force in physics refers to the vector sum of all the forces acting on an object. It accounts for both the magnitude and direction of each individual force, and determines the resulting acceleration or motion of the object according to Newton's second law of motion, F=ma.
What 3 ways can a force affect an objects motion?
Forces are created in many different ways. . . . . for example strong nuclear force electromagnetic force weak force and gravity
How many types of quantities?
there are three types of quantities:-1.Scalar quantities - Scalarsare quantities that are fully described by a magnitude (or numerical value) alone.2.vector quantities - Vectorsare quantities that are fully described by both a magnitude and a direction.3.Tensor quantities - tensors are quantities that are fully described by magnitude, direction and the plane thecomponent acts on.
Vector quantity will be described numerically or graphically?
it can be described in both. when graphically, it will be represented by an arrow in the direction of the vector and have the magnitude either written by it or you will have the arrow drawn to scale for the magnitude (length) of the arrow. numerically, you can break it down into its x, y, and z components and put them in from of i, j, and k respectively. ex a vector with x component of 3, y component of 2 and z component of 4 can be written as 3i +2j +4k
How do you find the net force on an object if the forces are going different ways?
Separate each force vector into x, y and z coordinates, then add them together. For example, three forces of (3, 5, 1), (-1, -2, 5) and (-1, -1, -1) are all acting a body; their sum is (3 - 1 - 1, 5 - 2 - 1, 1 + 5 - 1) = (1, 2, 5) which is the net force on that body. If the forces are only acting in one or two dimensions, then the mathematics are simpler, such as (2, 3) and (-4, -1), or just (2) and (-3). This may require some trigonometry to determine the size of each ordinate number; a vector of (3, -2, 4) has a real value of sqrt(29) in a direction roughly to the right-forward of and below the current position, and to return to a vector in coordinates is even harder.
