Revision Notes — Motion in One Dimension
Key concepts, formulas, and definitions from Motion in One Dimension for NEET-UG Physics preparation.
Key Topics to Revise
Position, Distance and Displacement
- Position is a vector quantity that specifies the location of an object with respect to a chosen reference frame
- Position vector in 1D: r = xi (where x is coordinate and i is unit vector)
- Distance is the actual path length covered by a moving object - always positive scalar
Speed and Velocity
- Speed is the rate of change of distance - always positive scalar quantity
- Velocity is the rate of change of displacement - vector quantity
- Average speed = Total distance / Total time taken
Acceleration
- Acceleration is the rate of change of velocity with respect to time
- Acceleration is a vector quantity - has both magnitude and direction
- Average acceleration = Change in velocity / Time taken
Kinematic Equations for Uniformly Accelerated Motion
- Valid only for motion with constant acceleration
- Four fundamental equations relate u, v, a, t, and s
- Can derive any equation from others using algebra
