Question

  1. - / 4 points does a negative acceleration always mean that an object is slowing down? yes no explain.

Explanation:

Brief Explanations

Acceleration is a vector quantity. The sign of acceleration depends on the chosen coordinate system. If an object is moving in the negative direction (as per the coordinate system) and has negative acceleration, it is actually speeding up. For example, if we take the right - hand direction as positive, an object moving to the left (negative direction) and having an acceleration to the left (negative acceleration) is speeding up. Only when the velocity and acceleration have opposite signs (e.g., positive velocity and negative acceleration) does the object slow down.

Answer:

B. No
