Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
Vector V 1 is 6.6 units long and points along the negative x axis Vector V 2 is 8.5 units long and points at 55 to the positive x axisWhat are the x and y components of vector V 1?
The x component of V1 is -6.6 the y component of V1 is 0.
When will be the vector projection and vector components are same?
Ans :The Projections Of A Vector And Vector Components Can Be Equal If And Only If The Axes Are Perpendicular .
Can be magnitude of a vector have negative value?
Vectors have magnitude and direction. The magnitude is always a positive number.
How do vector components compare in size to the vector from which they came?
That all depends on the angles between the vector and the components. The only things you can say for sure are: -- none of the components can be greater than the size of the vector -- the sum of the squares of the components is equal to the square of the size of the vector
What is meant by negative vector?
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
How will you multiply a vector by positive number?
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
Vector A lies in xy planeFor what orientation will both of its rectangular components be negative?
South West orientation makes both components negative.
Vector A lies in the xy plane.For what orientation will both of its rectangular components be negative?
South West orientation makes both components negative.
Is any quantity having a positive and negative values a vector?
No, vector, besides a value, has also a direction.

Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
Why two objects move in opposite direction one will have positive momentum and other negative momentum?
Quite simply, this means that momentum is a vector quantity; the direction is relevant. This is useful, for example, for calculations involving the conservation of momentum. Actually momentum is the product of velocity and mass, and velocity is also a vector quantity - thus, in this example, one object will have a positive velocity (more precisely: a positive component of the velocity along the x-axis, for example), the other, negative. Multiplying this velocity by the mass will also give a quantity which may be positive or negative (or rather, have positive or negative components).
What are the components of a vector?
The components of a vector are magnitude and direction.
The components of a vector or what?
The components of a vector are magnitude and direction.
Can a body have negative speedwhy?
No. The speed is the length of the velocity vector, and that is always zero or positive.
Does positive go to ground in a car battery?
NO! positive is red and black is negative negative is grounded to the frame of the car, and positive goes to the electrical components.
Vector V 1 is 6.6 units long and points along the negative x axis Vector V 2 is 8.5 units long and points at 55 to the positive x axisWhat are the x and y components of vector V 1?
The x component of V1 is -6.6 the y component of V1 is 0.
