Question

An object moving in a circle is represented by the motion map. Based on the map, at which point is the object accelerating toward the right? W X Y Z

Answer 1

z

Step-by-step explanation:

Answer 2

Z

Step-by-step explanation:

The object in the map is moving by circular motion: therefore, there is a force (called centripetal force) that pulls the object towards the centre of the circle.

According to Newton's second law,

`F=ma`

a force on the object corresponds to an acceleration, and this acceleration (called centripetal acceleration) has the same direction of the force. Therefore, since the acceleration is towards the centre of the circle as well, the only point of the trajectory where the acceleration is towards the right is at point Z.
