FAQs on Relative Velocity Video Lecture - Physics Class 11 - NEET

1. What is relative velocity?
Ans. Relative velocity refers to the velocity of an object or person as observed from another object or person in motion. It is the difference between the velocities of the two objects relative to a frame of reference.
2. How is relative velocity calculated?
Ans. To calculate relative velocity, you need to subtract the velocity of one object from the velocity of the other object. If the velocities are in the same direction, you subtract them. If they are in opposite directions, you add them.
3. Can relative velocity be negative?
Ans. Yes, relative velocity can be negative. Negative relative velocity occurs when the two objects are moving in opposite directions. It indicates that the objects are moving away from each other.
4. What is the significance of relative velocity in everyday life?
Ans. Relative velocity is significant in everyday life as it helps us understand and analyze the motion of objects or people in relation to each other. It is used in various fields such as transportation, sports, and navigation to calculate speeds, distances, and time.
5. How does relative velocity affect collisions?
Ans. Relative velocity plays a crucial role in collisions. It determines the impact force and the resulting motion after the collision. By analyzing the relative velocities of the objects involved, scientists and engineers can predict the outcome of a collision and design safety measures accordingly.
