Complete topic list for Motion in one Dimension in ICSE Class 9 Physics. Key concepts, sub-topics, and what to focus on for board exams.
Topics in Motion in one Dimension
Scalar and Vector Quantities
- Physical quantities are classified into scalars and vectors
- Scalars have only magnitude (e.g., mass, distance, speed, time, temperature)
- Vectors have both magnitude and direction (e.g., displacement, velocity, acceleration, force)
Rest and Motion
- Rest and motion are relative concepts
- A body is at rest if it doesn't change position relative to surroundings
- A body is in motion if it changes position relative to surroundings
Distance and Displacement
- Distance is total path length traveled (scalar)
- Displacement is shortest distance from initial to final position (vector)
- Distance is always positive, displacement can be positive or negative
Speed and Velocity
- Speed = distance/time (scalar, always positive)
- Velocity = displacement/time (vector, can be positive or negative)
- Uniform speed: equal distances in equal time intervals
