Questions and Answers

How can motion be defined?

As the distance traveled by an object only.
As the direction of movement without position change.
As a change in position over time. (correct)
As the speed of an object only.

What is the role of a reference frame in measuring an object's position?

It provides a set of moving objects for comparison.
It is a stationary group of objects against which motion is measured. (correct)
It determines the speed of the moving object.
It eliminates the need for any specific points of measurement.

What is the difference between distance and displacement?

Distance considers the path traveled, whereas displacement considers the shortest path between start and end positions. (correct)
Distance is a vector quantity, while displacement is a scalar quantity.
Displacement only measures speed, while distance measures time.
Distance is always greater than or equal to displacement. (correct)
