Question

an object is moving from right to left. its motion is represented by the oil drop diagram at the right. this object has a ________ velocity and a ________ acceleration. a. rightward, rightward b. rightward, leftward c. rightward, zero d. leftward, rightward e. leftward, leftward f. leftward, zero g. none of these

Explanation:

Step1: Determine velocity direction

Velocity is in the direction of motion. Since the object moves from right - to - left, the velocity is leftward.

Step2: Determine acceleration direction

The dots are getting closer together, which means the object is slowing down. An object slowing down has an acceleration in the opposite direction of its velocity. Since velocity is leftward, acceleration is rightward.

Answer:

d. leftward, rightward
