i'm writing a lab report in physics on the topic "VELOCITY VERSUS ACCELERATION ".
the question on the lab is "How does the distance traveled change with time as you are moving at a constant velocity versus constant acceleration?"
and my problem is about writing the hypothesis and test
i know what the hypothesis is, but i dont understand the "test"
what should i write there?
the teacher said it's "what u'r gonna do to determine if the hypothesis is correct or not", but still i dont understand. isn't that the procedure?
could someone explain please T^T
thank u very much

This is experimental science:
You hypothesize and then test the hypothesis. The test is the experiment.

In your example, create two tests, one with constant acceleration and one with constant velocity.

For constant acceleration, set a n inclined plane and use a steel ball rolling. The constant acceleration will be the vertical component of the force based on the angle of the plane.

Now set up a constant velocity example. One way to do that is to get an object on an inclined plane with a kinetic coefficient of friction that you know. Then set the inclined plane at an angle that will cause the object to move at terminal velocity, which will be constant over the surface. Measure the time it takes to move the distance.

Now compare the velocity you chose to the acceleration of gravity:32ft/s^2.
