How does the direction of the acceleration along determine if the object is speeding up or slowing down?
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then the object is speeding up.
How can you change only one component of the velocity without changing the speed?
Reverse the direction of the component.
If one component of a vector A is zero along the direction of another vector B then in what direction the two vectors will be?
opposite direction.
Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction
What two quantities are needed to get a vector quantity?
A magnitude, and a direction. Or, components in two directions, often called "x-component" and "y-component".

Reverse the direction of the component.
What is Vector quantity?
Associates the direction taken with the speedAny quantity that has direction and magnitude associated with it is considered a vector quantity. An example of a vector quantity would be velocity. It must be expressed with reference to a direction.-aerol_
If one component of a vector A is zero along the direction of another vector B then in what direction the two vectors will be?
opposite direction.
When can a nonzero vector have a zero horizontal component?
When the direction of the vector is vertical. Gravitational force has zero horizontal component.
What is speed is given direction?
The amount of speed in a given direction is the 'component' of speed in that direction. The total amount of speed AND the direction of the total speed is the 'velocity' of the moving object.
In electronics which component restricts the direction of movement of charge carriers?
Diode
What is speed in a given direction is called?
Speed in a given direction is velocity.
Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction
Why cannot the B-field of an infinitely long straight current-carrying conductor have a component in the direction of the current?
As induced magnetic lines exist in a plane perpendicular to the direction of flow of current, the component in the direction of current i.e cos 90 component will be zero. Recall cos 90 = 0. Hence the answer
What is crosswind direction?
A crosswind is any wind that is not in the same direction as travel. The crosswind component is perpendicular to the direction of travel ( 90 degrees). Mathematically, the crosswind component is the speed times the sine of the angle relative to the direction of travel. For example if a plane travels NORTH and there is a crosswind from the EAST ( 90 degrees) at 20 mph the crosswind component is 20 mph ( 20 sin90 = 20) For another example if a plane travels NORTH and there is a crosswind from the NORTHEAST ( 45 degrees) at 20 mph the crosswind component is 14.1mph ( 20 sin45 = 14.1)
What is the difference between a resultant vector and a component vector?
The resultant vector describes the complete vector, magnitude and direction; while the component vector describes a single component of a vector, like the x-component. If the resultant vector has only one component, the resultant and the component are the same and there is no difference.t
