Question

Which of the following do not depend on the frame of reference?
1. Mass of a stationary object
2. Distance between two points
3. Velocity
4. Distance

• A. $2\text{and}3$
• B. $1\text{and}3$
• C. $1\text{and}4$
• D. $1\text{and}2$

Answer 1

The correct option is D $1\text{and}2$

Mass of a stationary object and distance between two points have constant value irrespective of frame of reference.
Velocity and distance travelled depend on frame of reference.
Hence, option $\left(\text{a}\right)$ is the right choice.
