(a) What is the difference between 'distance travelled' by a body and its 'displacement' ? Explain with the help of a diagram.
(b) An ant travels a distance of 8 cm from P to Q and then moves a distance of 6 cm at right angles to PQ. Find its resultant displacement.
a)
DISTANCE | DISPLACEMENT |
1) It is the actual path covered by an object. | It is the shortest distance covered by an object. |
2) It is a scalar quantity. | It is a vector quantity. |
3) It cannot be negative. | It can be negative. |
b) Assume a right angle triangle with base 8 cm and height 6 cm.
Then the resultant displacement will be equal to:
= 10 cm
