What do you know about the motion of an object that has an average speed 1m/s?

What do you know about the motion of an object that has an average speed 1m/s?

Be serious people, it's for my 7th grade Physics Homework!

I'm so far covered velocity, motion, and speed; that's it!What do you know about the motion of an object that has an average speed 1m/s?Tthe moving object (mass) travels a distance of one meter in one second and that is an average velocity;that means the speed was not constant as it was moving. So dividing the distance travelled by the period of time traveled would give you only the average velocity.

The proof of this was given by a frenchman by the name Paris.



However the final velocity would be twice the average velocity which would be two meters per seconds.dont feel bad I learned that in the 8th grade.What do you know about the motion of an object that has an average speed 1m/s?
Well you cannot tell much about the motion. It could be going fast (accelerating) and then slowing down (decelerating) or it could be going a constant 1m/s.



Is that the whole question?What do you know about the motion of an object that has an average speed 1m/s?Is that all there is to the question? I guess you know that the speed is 1 m/s. What kind of motion do you mean?
True, it's hard to say much without more information. Have you been given a time or distance value?



The motion of the object may have been changing. That is, it might have stopped for a while, then it might have been going very fast like 10m/s, but ON AVERAGE, the motion of the object looked like a constant 1m/s.What do you know about the motion of an object that has an average speed 1m/s?speed is relative. from your point of view, the object is moving at 1m/s. It'd have a certain amount of kinetic energy. Or relativistically speaking, there will be a dilation of time, contraction of length and the mass of the object would increase by dm, where dm.c^2=kinetic energy of the object as the onject's velocity is increased from 0 to 1m/s. It'll move in a straight like if it is not subject to any force. but what is a straightline? in what geometry are our spacetime defined in actually?



oh, u mean.. what's it's momentum and etc?? do the calculation yourself.What do you know about the motion of an object that has an average speed 1m/s?
well you can say that it has the speed of 3600m/hr...but as far as the motion....you can say it maintains the same speed and direction unless another force is exerted upon it
That it is not traveling at a constant speed. I would assume that it is also traveling in a straight line. We can also say that the initial speed was zero and the final speed will be zero.What do you know about the motion of an object that has an average speed 1m/s?
all you can say is that if it travels for any number of seconds, it will travel that same number of meters, and if it travels a distance of any number of meters, it will travel for the same nuumber of seconds.



that is all you can know

you CANNOT know the following with the given info, no matter what other people say:

direction it is travelling or if direction is constant

initial or final velocity, or velocity at any instant

if speed is constant or non constant



actually, you can know that the object is not light because light only travels at the speed of light (duh) which is not 1m/s
Since the average speed is 1m/s, the object will move a distance of 1m in one second.



In t second it will move tm.



The actual speed may vary, that is the actual speed may be lesser or greater than the average speed, but the distance traveled can be found using the average velocity.
