What, if anything, is wrong with the following student's contention? If something is wrong, explain what it is and how to correct it. If nothing is wrong, explain why the contention is legitimate.
An object moving with a constant speed cannot have a constant acceleration.
Homework Answers
The contention of the student is wrong.
He states that "An object moving with a constant speed cannot have a constant acceleration". The keyword here is cannot. If we have even 1 example where constant speed results in constant acceleration his contention is wrong.
Suppose a body is moving in a straight line at a constant speed. Then its acceleration is always 0 as there is no change in velocity. This proves that his contention is wrong.
But suppose that the bosy moves with a constant speed but is changing its direction randomly, then the acceleration of the body keeps changing.
So the students contention should be "An object moving with a constant speed cannot always (may or may not) have a constant acceleration"

At the instant shown, a positively charged particle has a velocity that is parallel to a current-carrying wire. A student makes the following statement: "The force on the charged particle by the magnetic field is zero because the velocity is parallel to the current in the wire." What, if anything, is wrong with this statement? If something is wrong, explain the error and how to correct it. If the statement is valid, explain why.
