Question

Two students are studying for their upcoming physics exam and discussing the differences between directed motion and random motion. While reviewing the students make the following comments:

Kenny: Directed motion and random motion are two separate things. In directed motion you can use Newton’s Laws to describe the motion of individual objects, but when objects exhibit random motion they are equally likely to move in any direction. For Newton’s laws to apply there must be net movement in a particular direction.

Jesse: I thought that the difference between random motion and directed motion was just a matter of how closely you examine what’s going on. Newton’s Laws still apply for objects undergoing random motion, but it would be really hard to work out all the details.

React to each student’s statement and discuss what you think about random motion. Do Newton’s Laws apply? Can you reconcile Kenny and Jesse’s statements?

Explanation / Answer

Yes, i agree with Kenny as Directed motion and random are two separate thing

also as to change the stae of a body, we must apply external force

which is governed by the eqn F = ma
