An acceleration in the positive direction always means that a moving object is speeding up.

True

False


Sagot :

True, A moving object is constantly speeding up when there is an acceleration in the positive direction.

Our principle states that as an item slows down, the acceleration is going in the opposite direction of the velocity. This object, therefore, has a negative acceleration. The object has a negative velocity and is traveling in the opposite direction as it accelerates.

The rate at which a moving object's speed and direction change over time is known as its acceleration. When anything moves faster or slower, it is said to be moving faster in a straight line. Motion in a circle accelerates even at a constant speed because the direction is continuously changing. The acceleration of all other motions is influenced by both effects.

Due to its magnitude and direction, acceleration is a vector quantity. Speed is another vector quantity. The definition of acceleration is the velocity vector change during a period of time divided by the period of time. The instantaneous acceleration is based on the maximal ratio of the change in velocity (at a specific time and place).
