rate of change of velocity upon time is….
a)velocity.
b)accelaration.
c)momentum.
d)none of these
✅ Answers
Answerer 1
Rate of change of velocity upon time is acceleration.
In mathematical form– a=(v-u)/t, where v is final velocity, u is initial velocity, t is time and a is acceleration.
Hope that helps a little…
Answerer 2
acceleration
Answerer 3
b)accelaration.
Answerer 4
Obviously acceleration.
If u are driving a vehicle with speed of 50 km/hr and on giving accelerator it becomes 80 km/hr in 30 minutes 0.5 hrs.
Hence your acceleration would be acceleration= (change in velocity)/(time taken)
acc.=(80-50)/0.5=60 km per sq. hrs.
Answerer 5
Hello Helper Your friends, the phrase “rate of” is usually a ratio of change to time.
Rate of change of displacement is defined as velocity
And rate of change of velocity is defined as acceleration
But no such rate of change of acceleration!
Recall rate of doing work is POWER.
Any way for your query the right option is ACCELERATION.
It has been already rightly answered by two of our friends.
Answerer 6
Acceleration
