The components of a vector or what?
The components of a vector are magnitude and direction.
Direction of vector in space is specified by?
It is an integral part of the vector and so is specified by the vector.
What is the difference between vector addition and algebraic addition?
There is no difference between vector addition and algebraic addition. Algebraic Addition applies to vectors and scalars: [a ,A ] + [b, B] = [a+b, A + B]. Algebraic addition handles the scalars a and b the same as the Vectors A and B
What is the physical significance of null vectors?
Zero vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by . If a vector is multiplied by zero, the result is a zero vector. It is important to note that we cannot take the above result to be a number, the result has to be a vector and here lies the importance of the zero or null vector. The physical meaning of can be understood from the following examples. The position vector of the origin of the coordinate axes is a zero vector. The displacement of a stationary particle from time t to time tl is zero. The displacement of a ball thrown up and received back by the thrower is a zero vector. The velocity vector of a stationary body is a zero vector. The acceleration vector of a body in uniform motion is a zero vector. When a zero vector is added to another vector , the result is the vector only. Similarly, when a zero vector is subtracted from a vector , the result is the vector . When a zero vector is multiplied by a non-zero scalar, the result is a zero vector.
How do you solve for the rate of change in algebra?
The rate of change is often with respect to time t. suppose that d denotes the displacement of a particle, at time t, then you can find the speed with this formula:d=rt, then to solve for r we divide both sides by t and have d/t=rIn mathematics, it is useful to distinguish between velocity and speed. First, when considering motion of a particle in a straight line, specify a positive direction so that it is a directed line. Then the velocity of the particle is positive if it is moving in a positive direction and negative if it is moving in a negative direction. The speed of the particle is the absolute value of its velocity. In more advanced work, when the velocity is a vector v, the speed is the magnitude |v| of the velocity.
Vector addition is used when motion involves what?
more than one direction
The main difference between speed and velocity?
The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction.
What is velocity and why is it a vector?
Velocity is an indication of a speed, including a direction. It is a vector because that is how a vector is defined (a magnitude, including a direction).
Is momentum downwards?
Momentum is a vector, the product of a scalar (mass) & a vector (velocity). As such, its direction is whatever direction the velocity vector has.
The velocity of an object includes?
Velocity is a vector. As every vector in includes direction and magnitude (as 'oppose' to scalar). If that is what you meant by this vague question.
Acceleration involves a change in what?
It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.
Is velocity a vector?
True ,velocity is a vector quantity ,it is specified by a magnitude and direction.
Velocity is a measure of both an object's speed and its what?
Direction. Velocity is a vector quantity. Vectors have a scalar size and a vector direction.
What is a objects speed and direction?
Its called VELOCITY.
How would momentum be considered a vector?
momentum is mass x velocity and velocity is a vector and mass is scalar but scalar times vector = vector so momentum remains a vector
Why is velocity a vector quantity?
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
What is magnitude - like in a vector?
Here's a vector: "30 miles an hour, going north"The name of that vector is "velocity". It has a magnitude and a direction. Themagnitude of this velocity is 30 miles an hour. We usually call that "speed".The direction of this velocity is "north".The magnitude tells how big the vector is. The direction tells which way it points."30 miles an hour" is not a velocity. It's a speed. Speed is only the magnitude ofa velocity vector, because it has no direction. Once we know the direction, we canput it together with the magnitude, and we'll have a vector, called "velocity".
