Question

An object moves on a flat surface with an acceleration of constant magnitude.

Part A

If the acceleration is always perpendicular to the object's direction of motion, is the shape of the object's path circular, linear, or parabolic?

Part B

During its motion, does the object's velocity change in direction but not magnitude, change in magnitude but not direction, or change in both magnitude and direction?

During its motion, does the object's velocity change in direction but not magnitude, change in magnitude but not direction, or change in both magnitude and direction?

Part C

Does its speed increase, decrease, or stay the same?

a)the object's velocity changes in both magnitude and direction b)the object's velocity changes in magnitude but not direction c)the object's velocity changes in direction but not magnitude

Explanation / Answer

When acceleration is acting perpendicular to the direction of motion than following things occur :

1. The magnitude of velocity doesn't change.

2 . the direction of velocity changes every moment .

3 .particle moves along a circular path .

4. Since magnitude of instantaneous velocity is speed so speed of particle remain same .
