What kind of motion does the wheel of a bicycle moving with uniform velocity have?
Think it through first, then pick an option.
- a Linear
- b Periodic
- c Oscillatory
- d Translational
Answer and explanation
Correct answer: b Periodic
Right (key b in one of the two sources). At uniform velocity the wheel takes the same time for each turn, so it passes the same point from the same direction after a fixed interval: periodic motion.
Why the other options are wrong
- a Linear: In linear motion a body moves along a straight line. The wheel turns on its axle; it does not move along a line.
- c Oscillatory: Oscillatory motion goes to and fro about an equilibrium point. The wheel keeps turning one way.
- d Translational: Translational motion is the bicycle's straight advance, where the turning of the wheels is not counted. In the wheel's own turning different points go in different directions, so it is not translational.
