Topic 1.4: Reference Frames and Relative Motion

Front

What determines the direction and magnitude of quantities measured by an observer?

Back

The choice of reference frame.

Front

How can measurements from one reference frame be converted to another?

Back

Measurements from a given reference frame may be converted to measurements from another reference frame.

Front

What results in the observed velocity of an object?

Back

The observed velocity of an object results from the combination of the object’s velocity and the velocity of the observer’s reference frame.

Front

How do you combine the motion of an object and the motion of an observer in a given reference frame?

Back

Combining the motion involves the addition or subtraction of vectors.

Front

Is the acceleration of an object the same in all inertial reference frames?

Back

Yes, the acceleration of any object is the same as measured from all inertial reference frames.
