"Displacement"
ЁЯУПDistanceЁЯУП
The "length" of the path covered by a moving object in a given time is called the "distance" traveled by that object.
"Distance" = Speed × Time
↓Displacement↑
The difference between the final and initial "positions" of an object is called its "displacement".
ЁЯПОЁЯТиSPEEDЁЯПОЁЯТи
The "distance" traveled by an object in unit time is called the "speed" of the object.
"Speed" = Distance / Time
In the S.I. system, the unit of "speed" is meter per second (m/s).
ЁЯТиVelocityЁЯТи
The "displacement" of an object in unit time is called its "velocity".
"Velocity" = Displacement / Time Interval
In the S.I. system, the unit of "velocity" is meter per second.
ЁЯМкAccelerationЁЯМк
The rate of change of "velocity" of an object is called "acceleration".
"Acceleration" = Change in "Velocity" / "Time Interval"
