Question

An object P is moving with a constant velocity for 5min.Another object Qi is moving with changing velocity for 5 minutes. Out of these two object, which one has acceleration? Explain.

Answer 1

Answer:

Q is having a changing velocity .

hence it has acceleration .

explanation

a = dv/ dt

• if v is const

a= 0

• if v is variable

a has some value.

In simple words we accelerate or deaccelerate to increase or decrease speed . But if the speed is constant that means speed is not increasing or decreasing which means there is no acceleration.
