The Secretary Of Defense
ONLY if done for an emergency purpose and/or under the direction of competent authority (law enforcement - fire - or highway department personnel).
The Chairman of the Joint Chiefs of Staff has exclusive authority, direction, and control of the Joint Staff.
The Secretary of Defense supervises the military and make recommendations for military appropriations. The Secretary reports to the President and he is the commander-in-chief of all IS militarry forces,
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.
When you apply force at an angle to the direction of movement, the force gets divided into two components: one perpendicular to the direction of movement and the other parallel to the direction of movement. The component parallel to the direction of movement affects the acceleration of the object, while the component perpendicular to the direction of movement does not contribute to the acceleration in that direction.
The motion of a projectile is a combination of two motions, a constant speed motion in the horizontal direction, and an accelerated motion in the vertical direction. The velocity component that changes along the path is Vy.
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.
Speed in a given direction is velocity.
The vertical component of a vector is influenced by factors such as gravity, the direction of the vector, and the angle at which the vector is tilted with respect to the vertical axis. It represents the magnitude of the vector in the vertical direction.
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
If one component of vector A is zero along the direction of vector B, it means the two vectors are orthogonal or perpendicular to each other. Their directions would be such that they are at a right angle to each other.
