Distance
The total path traveled by an object (scalar, cannot be negative).
Displacement
The shortest distance from the starting to the final position (vector, can be negative).
Speed × Time
Formula for Distance
Velocity × Time
Formula for Displacement
Speed
The rate at which an object covers distance (scalar, always positive).
Velocity
The rate of displacement in a specific direction (vector, can be positive, negative, or zero).
Distance / Time
Formula for Speed
Displacement (s) / Time
Formula of Velocity
Acceleration
The rate of change of velocity over time (vector).
Change in velocity / Change in time
Formula for Acceleration
Average Speed
Total distance divided by total time.
Instantaneous Speed
Speed at a specific moment.
Constant Speed
Speed that does not change over time.
Instantaneous Velocity
Velocity at a specific point in time.
