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

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
