प्रश्न
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
उत्तर
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).
