Question

Which of the following statement(s) about motion is/are true?

• A. Motion of an object is only relative to the position of another object.
• B. Change in motion is the result of an applied force.
• C. Motion is change of location or position of an object with respect to time.
• D. All of these

Answer 1

The correct option is D

All of these

Motion cannot be measured independently. It is relative to the position of another object which we take as a reference frame. So if a body is changing its position and location from another object's perspective with respect to time, then it is said to be in motion. Hence, any change in motion is the result of an external activity.
