Can you tell by any experiment whether or not you are moving at a constant velocity?
You can’t and there is no way you ever will without detecting part of what’s going on outside. Motion can only be stated with reference to some other object. If there is no “other object” then there is no difference between being at rest, and moving with constant velocity.
Is it possible for such an object to have zero velocity in some inertial reference frame and not in another?
The answer to that is, clearly, “no” because we can have frames that are in motion relative to each other.
What needs to be true for a velocity to be constant?
To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed.
Why does Newton’s laws of motion do not hold true in a non-inertial frame of reference?
Such an accelerating frame of reference is called a non-inertial frame because the law of inertia does not hold in it. That is, an object whose position is judged from this frame will seem to spontaneously change its velocity with no apparent non-zero net force acting upon it.
Is it possible to have a description of motion without a frame of reference quizlet?
Is it possible to have a description of motion without a frame of reference? No, because motion is relative. It is not possible to describe the motion of the body without a frame of reference. Motion is relative and is always described with respect to a chosen frame of reference.
Is there such thing as 0 velocity?
Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity.
Which frame of reference has no constant velocity?
inertial frame of reference
In classical physics and special relativity, an inertial frame of reference is a frame of reference that is not undergoing acceleration.
What is a real life example of constant velocity?
Answer to Essential Question 2.3: Some examples of constant velocity (or at least almost- constant velocity) motion include (among many others): • A car traveling at constant speed without changing direction. A hockey puck sliding across ice. A space probe that is drifting through interstellar space.
How do you prove constant velocity?
Constant velocity means that the object in motion is moving in a straight line at a constant speed. This line can be represented algebraically as: x=x0+vt x = x 0 + vt , where x0 represents the position of the object at t=0 , and the slope of the line indicates the object’s speed.
How do you know if an experiment is a controlled experiment?
In a controlled experiment, you compare an experimental group with a control group. Ideally, these two groups are identical except for one variable, the independent variable. Field Experiments: A field experiment may be either a natural experiment or a controlled experiment.
Are the laws of physics the same in all inertial frames?
The laws of physics are the same in all inertial frames (this is known as Galilean invariance ). Put in another way, there is no experiment that you could do to determine which reference frame you are in (Einstein used this hypothesis to devise the theory of Special Relativity).
What are some examples of things that are not experiments?
Examples of Things That Are Not Experiments 1 Making a model volcano. 2 Making a poster. 3 Changing a lot of factors at once, so you can’t truly test the effect of the dependent variable. 4 Trying something, just to see what happens. On the other hand, making observations or trying something, after making a… More
What is the speed of s relative to the laboratory frame?
The speed of S’ relative to the laboratory frame is thus u, start subscript, A, end subscript, u A . To make things easier, we choose the axes in the two frames to point in the same directions, and for them to coincide at time t, equals, 0, s, t = 0 s.
