Speed & Velocity Flashcards
Speed
distance object travels in unit of time, Scaler quantity, (s)
S.I unit- m/s
Types of speed
Average speed
Instantaneous speed
Uniform speed
Non uniform speed
Average speed
Total distance covered over total time taken
speed= d/t
Instantaneous speed
Speed at any moment in time
Uniform speed
The constant speed, when object covers equal distance in equal intervals of time
Non uniform speed
The variable speed, when object covers unequal distances in equal instances of time
Velocity
speed with direction, Vector quantity
S.I unit- m/s
Types of velocity
Average velocity
Instantaneous velocity
Uniform velocity
Non uniform velocity
Average velocity
Displacement of an object over total time
Velocity= s/t
Also by, finding the average of 2 velocities
velocity= V+u/2
Instantaneous velocity
Velocity at a moment in time
