Question: What is Velocity Class 9 Physics?
- The rate of change of distance with time
- The speed of an object
- The mass of an object
- The force acting on an object
Answer: A) The rate of change of distance with time
Solution: Velocity, in the context of Class 9 physics, is a fundamental concept in the study of motion. It is best described as the rate of change of an object’s distance over time. In other words, velocity tells us how fast an object is moving in a particular direction. To calculate velocity, you can use the formula:
Velocity = Change in Position/Change in Time
- This formula helps in quantifying both the speed and direction of motion. It’s important to note that velocity is a vector quantity, which means it has both magnitude (speed) and direction. It’s different from speed, which is a scalar quantity and only represents how fast an object is moving, irrespective of its direction.
What is Velocity Class 9? it’s essential to understand that velocity is not just about speed; it includes direction as well. It is a crucial concept for analyzing and describing the motion of objects in a more comprehensive manner.
