Revision Notes — Motion in a Straight Line
Key concepts, formulas, and definitions from Motion in a Straight Line for CUET (UG) Physics preparation.
Key Topics to Revise
Position, Path Length and Displacement
- Position defines the location of an object with respect to a reference frame using coordinates
- Path length (distance) is the actual length of path travelled by an object - always positive
- Displacement is the shortest distance between initial and final positions with direction
Average Speed and Average Velocity
- Average speed = Total distance / Total time taken (always positive)
- Average velocity = Total displacement / Total time taken (can be positive, negative, or zero)
- Average velocity is slope of position-time graph between two points
Instantaneous Velocity and Speed
- Instantaneous velocity is velocity at a particular instant of time
- Mathematically: v = dx/dt (derivative of position with respect to time)
- Instantaneous speed is magnitude of instantaneous velocity
Acceleration
- Acceleration is rate of change of velocity with respect to time
- Can be positive (speeding up in positive direction) or negative (retardation)
- Direction of acceleration determines whether object speeds up or slows down
