Question

2.The ratio of speed to velocity made by an object moving in a curved path is

(A) zero

(B) 1

(C) less than one

(D)(d) greater than one​

Answer 1

The ratio of speed to velocity made by an object moving in a curved path is greater than one.

• The mathematical formula to calculate the speed of a body is, Speed = Total travelled distance/Time.
• The mathematical formula to calculate the velocity of a body is, Velocity = Total displacement/Time.
• Now, in the case of a curved path the total travelled distance will be length of the curved path, whereas the displacement will be the straight-line distance between the two end points of the curved path.
• So, for a curved path,

Total travelled distance > Total displacement

Total travelled distance/ time > Total displacement/time

Speed > Velocity

Speed/Velocity > 1

Speed : Velocity > 1

• Hence, the ratio will be greater than 1.
