Question

A freely falling object travels 4.9 m in 1st second, 14.7 m in 2 nd second, 24.5 m in 3rd second, and so on. This data shows that the motion of a freely falling object is a case of :

विकल्प

• uniform motion

• uniform acceleration

• no acceleration

• uniform velocity

Answer 1

uniform acceleration

The displacement of the body in equal interval of time is unequal, but acceleration is constant. The acceleration will thus be uniform, so the answer is (b).
