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
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
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.
say
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...
To expand your answer into an essay, you can provide further explanation and examples. Here's a suggestion for structure and content:
Introduction:
- Begin with a clear thesis statement that states your position on whether an object can be increasing in speed as its acceleration is decreasing.
- Provide a brief overview of acceleration and its relationship to speed.
Body Paragraph 1:
- Start by explaining the concept of acceleration and its effect on speed.
- Discuss how acceleration causes a change in an object's velocity, which in turn affects its speed.
- Explain that when acceleration is positive (in the direction of motion), it causes an increase in speed, while negative acceleration (opposite to the direction of motion) leads to a decrease in speed.
Example 1:
- Choose a scenario where an object is accelerating positively, resulting in an increase in speed.
- Explain the situation in detail, including the forces involved and the object's motion.
- Provide any relevant numerical values, such as initial speed and acceleration, to support your explanation.
- Show how the object's speed is increasing due to the positive acceleration.
Body Paragraph 2:
- Shift the focus to the concept of deceleration, which occurs when an object's speed decreases.
- Explain that deceleration is a type of negative acceleration, causing a decrease in speed over time.
- Highlight that deceleration is a separate concept from acceleration and cannot occur simultaneously with acceleration.
Example 2:
- Choose a scenario where an object is decelerating, resulting in a decrease in speed.
- Describe the circumstances in detail, such as the forces involved and the object's motion.
- Present any relevant numerical values, such as initial speed and deceleration rate, to support your explanation.
- Demonstrate how the object's speed is decreasing due to the deceleration acting against its initial motion.
Conclusion:
- Summarize the main points made in the essay.
- Restate your thesis statement in a concise manner.
- Conclude by emphasizing that an object cannot be increasing in speed while its acceleration is decreasing because acceleration and deceleration are separate and distinct concepts.
Remember to use proper essay structure, including topic sentences, supporting evidence, and linking sentences to ensure a logical flow in your essay.
Note: While the above suggestions provide a basic framework for your essay, it's essential to review your course materials, textbooks, and any other relevant resources to ensure accuracy and completeness in your response.
