NEET Class neet Answered
velocity increase and acceleration increase true or false
Asked by farzinnowshin | 17 Dec, 2022, 11:19: PM
Expert Answer
Acceleration = dv/dt , where v is velocity
Acceleration is rate of change of velocity / If velocity increases at constant rate , i.e. dv/dt = constant ,
then acceleration is constant , neither increases nor decreases.
if acceleration or dv/dt is not constant and it depends on some power of time t , then acceleration is not constant.
Acceleration increases if sign of dv/dt is positive and it depends on some power of time t .
Acceleration decreases if sign of dv/dt is negative and it depends on some power of time t .
