Hi :) is decreasing acceleration non uniform acceleration ? anyone able to explain I’m rlly confused. Thanks!

Yes

Explanation:

Non uniform acceleration is any acceleration that is not constant.

If you look at the graphs I have drawn in the above picture, the first two graphs shows a uniform acceleration.

The first graph is a positive acceleration, which means that the object is moving faster and faster at a constant rate. The second graph shows a deceleration, or negative acceleration, which means that the object is moving slower and slower at a constant rate.

For velocity- time graphs, acceleration can be seen by its gradient. So if the slope of the graph doesn't change, it has a uniform acceleration.

Graph 3 shows zero acceleration since the object is moving at a constant velocity (or speed). Thus, the object does not acceleration.

Graphs 4-7 shows a non uniform acceleration.

In graph 4, the object has a decreasing acceleration since the gradient of the graph is decreasing. This can be seen by the slope getting gentler and gentler.

Graph 5 shows an increasing deceleration, since the graph is getting steeper and steeper and the velocity is decreasing with time.

Graph 6: increasing acceleration

Graph 7: decreasing deceleration
