When an object is seen moving in relation to a stationary object the stationary object is called the frame of reference or reference point?
Why do reference points that are stationary are usually chosen to determine whether an object is in motion?
When an object is seen moving in relation to a stationary object the stationary object is called the?
Answer #1: A reference point should be stationary from the point of view of the observer. =============================== Answer #2: As soon as you said a "moving car", you showed us that you already have a reference point, and that the car is moving relative to it. If you want to use the car as a reference point, fine and dandy. Then the car is not moving. The pavement on the road, the trees, and the…
When an object is seen moving in relation to a stationary object the stationary object is calle the?
No you cannot. A displacement-time graph is concerned only with radial motion: displacement from a fixed point of reference. Any transverse motion is completely ignored. Thus, if you had a body going around in a circle about the point of reference, its speed would be recorded zero even though it is far from stationary.
If a bird hovers inside a train whilst that train is moving then presumably it is travelling at the same speed as the train Why is this and why is it not thown to the back of a carriage?
What pushes us back is a change in velocity (i.e., an acceleration), not the velocity itself. You might as well say that the train is stationary, and that planet Earth is moving under the train. In outer space, there is no fixed reference point; and it doesn't make sense to speak of the "real" velocity. A velocity must always be indicated with relationship to some reference point. Using the Earth as a reference point is…
An object is in motion when it changes its position with respect to a given frame of reference (usually it is the observer or a fixed point in space). Motion can only be visualized when it is seen against a frame of reference. but as we move on to advanced physics, we see that there is no point we can consider as stationary. Einstein solved this porblem while proposing his theory of relativity. he said…
The Doppler effect is observed when the straight-line distance between the source and observer is changing. It makes no difference which one thinks it is stationary and which one thinks it is moving, and there is no point in starting that argument. The fact is that each of them is moving in the other's frame of reference, and that is the only statement that can apply truthfully to the situation.
