HELP!!! |
Dear all,
I'm asking for a little bit of help from those of you who love
physics. I need 3 physics questions and a method of solving them. 1
question on motion, 1 question on force, and finally 1 question on
energy. Would anyone kindly give me some of these questions with the
detail working. These questions are for me to practice for my mid-term
exam that's coming in about 2 days. please kindly write the detail
working for each questions. In addition, the answers to these
questions should be able to derived without using a calculator
Thank you very much
AJ

That is more than 'a little bit'
There are an almost infinitude of text books with these sort of questions.
Secondly, a specific three questions will not give you the fluency in
solving exam questions.
And with two days to go, is this not a bit last minute?
The web alone has an abundance of material.
Would anyone kindly give me some of these questions with the
detail working.
Search the web, search the library.... We cannot pass the exams for you.
These questions are for me to practice for my mid-term
exam that's coming in about 2 days.
A lot on these newsgroups love physics, you have two days, are you sure do
love physics?
Why not post 2 weeks or more ago?
please kindly write the detail
working for each questions. In addition, the answers to these
questions should be able to derived without using a calculator
Thank you very much
AJ
'in detail' - would you like some icing with it as well?
Somehow I think I've just replied to yet another wind-up.

1. An object is seen to move a distance of 10m in a Northerly
direction in 2s. It moves with uniform speed. What is its
velocity?
v = change in position / change in time
v = 10 / 2
v = 5 m/s [North]
2. The object has mass M. What force is being applied to it (assume
no friction, etc.)?
F = mass * acceleration
F = M * a
F = M * 0 (it moves at constant speed)
F = 0 N
3. How much energy is used in moving the object through the 10m
distance?
W = force * distance
W = F * d
W = 0 * 10
W = 0 J
There you go. A comprehensive set of problems, to be sure. Don't
forget your units.

Get off the internet, open your book, do ALL the problems.
Go buy a Schalms Outline on Physics for problems.
Your lack of planning does not cause an emergency on my part.

Doesn't your book come with practice questions? Understanding is what you
need. It's that simple. Read about everything you don't understand
yet,using your book, the library and the internet. Forums can't be relied
on, a waste of time for a person in your current position.

Classes on physics for secondary school teachers are typically
failures. Such people need to be taking real physics classes, so that
they can at least comprehend the high school level physics they're
supposed to be teaching.
