3. Distance
Length of a path between two points is called displacement.
Units:
Meter, Kilometer or Light year
Distance is a scalar quantity

4. Displacement
The shortest distance between two points is called displacement.
Units: Meters or Kilometers
Displacement is a Vector quantity

5. Speed
The distance covered by an object in unit time is called speed.
Formula:
Speed is a scalar quantity
Units: m/s

6. Velocity
The displacement covered by an object in unit time is called velocity.
OR
Rate of change of displacement of an object is called velocity.
Formula:
Velocity is a vector quantity
Units: m/s

7. Speed vs Velocity

8. Uniform speed
A body has uniform speed if it covers equal distance in equal intervals of
time.

10. Uniform Velocity
A body has uniform velocity if it covers equal displacement in equal
intervals of time.
