Question

Velocity of particles is constant when acceleration

Answer 1

Velocity of particle is constant

Answer:-

When acceleration is Zero.

so,

Slope of V-T graph gives acceleration .

a= dv/dt

a=d(constant)/dt.

Differentiating a constant comes out to be zero.

Therefore,

a=0 m/s^2.

Note:-

when acceleration is non zero then velocity must be changing because acceleration is defined as the rate of change of velocity.

I.e. a=d(variable)/dt

a=x m/s^2.

[x=some value].
