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.
ONLY if done for an emergency purpose and/or under the direction of competent authority (law enforcement - fire - or highway department personnel).
Reverse the direction of the component.
The Chairman of the Joint Chiefs of Staff has exclusive authority, direction, and control of the Joint Staff.
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_
The Secretary of Defense is the major department head with authority over the US military. The Secretary of Defense is a civilian appointed by the President and is responsible for the overall management and direction of the Department of Defense, which includes the branches of the military.
opposite direction.
When the direction of the vector is vertical. Gravitational force has zero horizontal component.
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.
Diode
Speed in a given direction is velocity.
the horizontal component remain unchanged because there in no acceleration in horizontal direction
