Study Notes
NCERT Solutions for Class 9 Science Chapter 8: Motion
- The primary focus of NCERT Solutions for Class 9 Science is to provide comprehensive learning material for students.
- The intention of NCERT Solutions for Class 9 Science is to facilitate learning and understanding of scientific concepts.
Displacement and Distance
- The total distance travelled by an object is not necessarily equal to its displacement.
- The odometer of an automobile measures the total distance travelled.
- An object can have zero displacement even after moving through a distance, if it returns to its initial position.
Speed and Velocity
- Speed and velocity are not the same; velocity has both magnitude and direction.
- The magnitude of average velocity is equal to the average speed of an object only when the object moves in a straight line.
Displacement and Motion
- It is possible for an object's displacement to be zero, even if it has moved through a distance.
- If a person jogs around a circular park and returns to the initial position, the magnitude of displacement is zero.
- A true statement about displacement is that it is a vector quantity having both magnitude and direction.
- Average speed measures the total distance travelled by an object over a given time period.
- An object's speed is equivalent to its velocity only when it moves in a straight line.
