FAQs on Velocity Video Lecture - Class 9
| 1. What is velocity in physics? |  |
Ans. Velocity in physics is the rate of change of an object's position with respect to time. It is a vector quantity that includes both magnitude (speed) and direction. It is often measured in meters per second (m/s).
| 2. How is velocity different from speed? | |
Ans. Velocity and speed are related but different concepts in physics. While speed only considers the magnitude of an object's motion, velocity includes both magnitude and direction. For example, if a car is traveling at 60 km/h due north, its speed is 60 km/h, but its velocity is 60 km/h north.
| 3. Can velocity be negative? | |
Ans. Yes, velocity can be negative. In physics, negative velocity indicates that an object is moving in the opposite direction of a chosen reference point. For example, if a car is initially moving east at 20 m/s, but then starts moving west at 10 m/s, its velocity changes from positive to negative.
| 4. How is average velocity calculated? | |
Ans. Average velocity is calculated by dividing the change in an object's displacement by the change in time. It is represented by the formula: average velocity = (final displacement - initial displacement) / (final time - initial time). The unit of average velocity is usually meters per second (m/s).
| 5. What is the difference between velocity and acceleration? | |
Ans. Velocity and acceleration are both related to the motion of an object, but they represent different aspects. Velocity refers to the rate of change of an object's position, while acceleration refers to the rate of change of an object's velocity. Acceleration measures how quickly an object's velocity is changing, either in terms of acceleration or deceleration.
