Topics in Motion in one Dimension

1

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)
2

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
3

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
4

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

Key Concepts

Scalars have only magnitude (massDistance is the total path lengthSpeed = distance/time (scalarAcceleration = change in velocity/time =Distance
