An ant travels a distance of 3 cm from P to Q and then moves a distance of 4 cm at right angles to PQ. Find its resultant displacement.

If a bus travelling at 40 m/s is subjected to a steady deceleration of 5 m/s², how long will it take to come to rest?

What is the difference between ‘distance travelled’ by a body and its ‘displacement’? Explain with the help of a diagram.

Define motion. What do you understand by the terms ‘uniform motion’? Explain with examples.

Define speed. What is the SI unit of speed?
