Acceleration
The rate of change per unit time is called acceleration.It is a vector quantity and it is denoted by "a".In SI System unit of a acceleration is m/s2.
Initial Velocity= u
Final velocity = v
Time taken = t
Acceleration = Final velocity - initial velocity
Time taken
= v-u
t
Note*
# If a body starts from rest to motion u= 0
Initial Velocity= u
Final velocity = v
Time taken = t
Acceleration = Final velocity - initial velocity
Time taken
= v-u
t
Note*
# If a body starts from rest to motion u= 0
# If a body suddenly stops due to the application of external force, like- by applying brakes, v=0
# If a body is thrown vertically upward, at maximum height, v = 0
