Question

A body is moving along a straight path. What will happen to the body in the absence of an external field?

(a) It will stop

(b) It will move with the same speed in a different path

(c) It will move with the same speed along the same straight path

(d) It will move with a reduced speed along the same path

Answer 1

Right option is (c) It will move with the same speed along the same straight path

The explanation is: Galileo stated that on a horizontal plane an object should move with a constant velocity in a straight line path. Therefore a body moving along a straight path will continue to move in the same direction with the same speed even in the absence of external forces.
