Question

A physics student states that a body in 'uniform motion in a straight line' will continue in that state unless acted upon by an external force. According to the lecture material, the phrase 'in a straight line' in this context is:
Options
A Essential, because uniform motion can occur on a curve.
B Redundant, because uniform motion itself implies motion in a straight line.
Correct Answer
C Incorrect, as uniform motion only refers to constant speed.
D Necessary to distinguish it from motion in a circle.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The lecture explains that uniform motion itself implies motion in a straight line, as any curved motion involves acceleration, even if the speed is constant.

Hint

What type of path is associated with zero acceleration?
