Yes
, a vector can have a component equal to zero and still have a nonzero magnitude.
Can a nonzero vector have a zero component?
A nonzero vector can have a
zero
component. Any non zero vector along y- axis has a zero component on x- axis.
Can a velocity of an object have a component equal to zero and still have nonzero magnitude?
A
2D vector
can have a component equal to zero even when its magnitude is nonzero.
Does a zero vector have zero magnitude?
The zero vector (
vector where all values are 0
) has a magnitude of 0, but all other vectors have a positive magnitude.
Can a vector have a zero component?
Yes,
a vector can have a component equal to zero
and still have a nonzero magnitude.
Can a body have zero velocity but a non zero acceleration?
Acceleration is the rate of change of velocity of an object with respect to the time over which this change occurs.
It is possible to have a non-zero value of acceleration when the velocity of a body is zero
. … This means that the change in the velocity is still taking place when the velocity of the object reaches zero.
Can resultant of two vectors be zero?
yes
, when the two vectors are same in magnitude making an angle of 2π3 with each other. …
Will the cross product of two vectors be zero?
If two vectors have the same direction or have the exact opposite direction from each other (that is, they are not linearly independent), or if
either one has zero length, then their cross product is zero
.
What does a zero vector mean?
: a vector which is
of zero length and all of whose components are zero
.
What is null vector and unit vector?
A vector having zero magnitude (arbitrary direction) is called the null (zero) vector. The zero vector is unique. For eg:- A point have no magnitude and an arbitrary direction. Unit vector is
a vector of unit length
. If u is a unit vector, then it is denoted by u^ and ∣u^∣=1.
What does non zero vector mean?
Not equal to zero
. … A nonzero vector is a vector with magnitude not equal to zero.
Does it make any sense to call a quantity a vector when its magnitude is zero?
Does it make sense to call a physical quantity a vector when its magnitude is zero ?
Yes,null vector has a definite physical significance
.
Why is acceleration not zero when velocity is zero?
For the most part velocity is not zero if an object is accelerating. Since acceleration is the change in velocity over time, there has to be a change in velocity for something to accelerate. … If the
velocity is constant
however, the acceleration is zero (because the velocity isn’t changing over time).
Can a body have 0 velocity and still be accelerating example?
Yes
, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction. Now, suddenly a force acts on it and tries to accelerate the object in the reversed direction.
Why retardation is called negative acceleration?
The change in velocity of the object is zero. Hence, the object at rest or in uniform motion has zero acceleration. …
If the velocity of the object decreases then the object is said to have
a negative acceleration and the meaning of retardation is decreased. Therefore, retardation means negative acceleration.
Can the resultant of two unequal force be equal to zero?
Two vectors of unequal magnitude
can never sum to zero
. If they point along the same line, since their magnitudes are different, the sum will not be zero.
