Question

give two examples of zero acceleration​

Answer 1

Answer:

No acceleration means no change in velocity. For example an apple thrown in space. ... A photon has zero acceleration because it can't be accelerated. All other examples of zero acceleration are where the “thing” is moving at a constant velocity relative to an inertial reference frame.]

Answer 2

Step-by-step explanation:

Zero acceleration is an acceleration, just with zero magnitude.

Ex: Suppose a car is running with velocity 6m/s initially. Now driver pushed his car's accelerator and reaches his car speed to 12m/s in 3seconds.

So, Here there is a change in velocity as time spents. So, in this case there must be acceleration in the car and here

Acceleration=(final velocity-initial velocity) /time taken in velocity change

i.e. a=(12-6)/3 = 2 (m/s^2)

So, for acceleration of a body to be zero, change in velocity of a body must be equal to zero.
