In a given system, the electric field direction changes from positive to negative when the source of the electric field changes its charge from positive to negative.
Velocity can have positive or negative value depending on the direction of the change in position. Positive velocity indicates motion in one direction, while negative velocity indicates motion in the opposite direction.
Yes, that is correct. The direction of the electric field at any point represents the direction in which a positive test charge placed at that point would experience a force. If a negative test charge is used, the force it experiences would be in the opposite direction of the electric field.
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
Yes, acceleration is a vector quantity that involves both magnitude and direction. It indicates the rate of change of velocity with respect to time and can be positive or negative, depending on whether it is in the same direction as the velocity (positive) or opposite direction (negative).
The direction of motion can be determined by observing the change in position of an object over time. If the position is increasing, the object is moving in the positive direction; if it is decreasing, it is moving in the negative direction. Additionally, the sign of the velocity can indicate the direction of motion: positive for forward motion and negative for backward motion.
Velocity can have positive or negative value depending on the direction of the change in position. Positive velocity indicates motion in one direction, while negative velocity indicates motion in the opposite direction.
Nobody. Positive and negative electric changes exist from the earliest stages of the Big Bang.
Yes, that is correct. The direction of the electric field at any point represents the direction in which a positive test charge placed at that point would experience a force. If a negative test charge is used, the force it experiences would be in the opposite direction of the electric field.

positive or negative change of velocity or change of direction of the speed vector
The direction of the current refers to the flow of electric charge. In a circuit, current flows from the positive terminal of the voltage source to the negative terminal, opposite to the direction of electron flow.
negative*negative=positive negative/positive=negative negative\negative=positve negative-positive=change the sign to a plus and then change the number after the sign and get your answer negative +positive=which ever numbr is bigger minus positive+positive=positive

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°.
Protons have a positive charge, neutrons are neutral, and electrons have a negative charge.
Direct current (DC) does not change direction in electricity. It flows consistently in one direction from the positive to the negative terminal of a power source, unlike alternating current (AC) which changes direction periodically.
