Question

In deep space, an object is traveling at constant speed in a straight line. Then it is observed to change its direction of travel. What can the observer conclude?

A.
The forces acting on the object must have changed.
B.
The object's mass must have changed.
C.
The object's speed must have changed.
D.
Enough time had elapsed to slow the object down.

Answer 1

Answer:

A) the force acting on the object must have changed

Answer 2

Answer:

Option A

Explanation:

Among the four options given, the correct is option A

In deep space, there is some gravitational force, a force that exists between two objects. Although it would be very less, but we can’t say that there is no force acting.

Hence if the object's direction is changed in deep space, then there is change in the forces acting on the object
