Question

Essay Question: discuss whether or not it is possible for an object to be
increasing in speed as its acceleration is decreasing. For
either position you take, use examples as part of your
explanation.
CAN SOMEONE HELP SUGGEST AN EXAMPLE THAT WOULD HELP CONFIRM MY ANSWER. I'M KINDA LOST. My answer isn't long enough to be an essay so can you help me elaborate my answer.
(I put it all in sentence form already. I'll just give the points from each sentence. )
ANSWER:
1. Yes
2. Acceleration= to increase speed
3. deceleration= when speed is decreasing.
4. Acc. & Dec cannot be used at the same time rather it is separate. Either the object acc, dec, or moves at constant speed.

What Else should I include to make it an essay? & Also, Can someone help me give 2 examples to understand this question cuz i'm lost! TEST TMRW ASAP

Answer 1

speed is a scalar and has no direction. Acceleration is a vector and direction matters so if an object is changing direction, it's acceleration changes independently of speed.
So I would say yes it is possible for it to increase in speed as acceleration decreases

Answer 2

acceleration is rate of change of velocity (not speed)
deceleration means negative acceleration I suppose, but a physicist just says negative acceleration. I would not use that word!

so let's say I an going east at 10 m/sec
if my acceleration is +2 m/s^2 east
then in one second I will be going 10 +2(1) = 12 m/s
BUT
what if my acceleration east is just 1 m/s^2 ?, still + but less.
Now my velocity east in one second will be 10 + 1 (1) = 11 m/s

My object is STILL increasing in velocity east (from 10 to 11 instead of from 10 to 12), although my acceleration decreased.

Answer 3

Ok THANKYOU so much for the clarification and the example. That sure did help A lot. Massive Thanks. Let's just hope this test goes well...
