Displacement:
- Definition: The straight-line distance between the initial and final positions of an object, along with the direction of movement.
- Units: Meters (m)
Distance:
- Definition: The total path length traveled by an object, regardless of direction.
- Units: Meters (m)
Speed:
- Definition: The rate at which an object covers distance. It is a scalar quantity (no direction).
- Formula: Speed=DistanceTime\text{Speed} = \frac{\text{Distance}}{\text{Time}}Speed=TimeDistance
- Units: Meters per second (m/s)
Velocity:
- Definition: The rate of change of displacement, which includes both speed and direction (vector quantity).
- Formula: Velocity=DisplacementTime\text{Velocity} = \frac{\text{Displacement}}{\text{Time}}Velocity=TimeDisplacement
- Units: Meters per second (m/s)
Acceleration:
- Definition: The rate of change of velocity of an object. It tells you how quickly an object’s velocity is changing.
- Formula: Acceleration=ΔvΔt\text{Acceleration} = \frac{\Delta v}{\Delta t}Acceleration=ΔtΔv (change in velocity over change in time)
- Units: Meters per second squared (m/s²)
