Question : Please tell me te equations so that I could study my lessons well... the* equations... sorry for my typo...
Answer : The real dilemma is = how do we define Uniform motion.
Is motion a wave? Do wave move Uniformly? When a mass fall toward the earth due to the power of gravity that caused to move , does it fall uniformly with uniform acceleration?
The answer is no.The reason is the Gravity field is not constant during the free fall of the mass.
We are not able to measured instantaneous velocities whether it inertial motion or non inertial motion . We can only measure averages.
So we calculate velocities on the basis of acceleration ,the value of acceleration is only an average.
Formula to estimate the average velocity is as follows;
V= a x t
where v =is velocity ,a= is average acceleration and t= is the time at the instance that the mass has moved.
The average acceleration is then considered constant and therefore uniform.
However in reality Uniform motion in terms of uniform velocity and and acceleration does not exist in the reality of the Universe.
The proof of this stems from the fact ..
Question : Options:
-uniform acceleration? or
Give reasons for your choice.
Answer : Uniform acceleration. As the object falls DOWN due to gravity, the plane will apply a NORMAL force (that is, a force in the opposite direction) equal exactly to how much of that DOWN force gets applied to the plane. If the plane applies friction greater than the remaining force the object will experience a negative uniform acceleration until it comes to a stop (which is still uniform accel.). These forces will remain uniform until a change occur.
Question : i graphed an acelleration graph and every .1 sec the velocity increased ten then in another .1 secs it decrased by ten. The shape of the graph went up and down. Is this accelleration graph an example of uniform motion. so ijn .1 secs the velocity was 76 then in .2 secs it was 70 then in .3 secs it went back to 76 and so on. Is this uniform motion? Why? How do you know by looking at the graph? Thanks a lot
Answer : Uniform motion would always have an acceleration of 0, and a constant velocity. You know that this isn't uniform motion, because when you look at the acceleration graph, it's not at 0.
