Analyzing Position-Time Data

The video tutorial demonstrates an experiment on uniform motion with constant velocity. It begins with setting up the air table and equipment, ensuring the table is level. The experiment involves launching a puck with a moderate velocity and using a spark timer to record data points. The data is then analyzed by selecting consecutive points, determining time intervals, and plotting a position-time graph. The slope of the graph indicates the puck's velocity.

What is the first step in setting up the experiment for uniform motion?

• Launch the puck with a moderate velocity.

• Plot the data on a position-time table.

• Set the frequency of the spark timer.

• Place the carbon sheet and data sheet on the air table.

How do you ensure the air table is ready for the experiment?

• By checking if the table is inclined and adjusting it to be parallel to the ground.

• By placing one of the pucks in a corner.

• By setting the frequency of the spark timer.

• By launching the puck with a moderate velocity.

What should be done after setting the frequency of the spark timer?

• Analyze the datasheet.

• Launch the puck with a moderate velocity.

• Plot the data on a position-time table.

• Choose six consecutive points for analysis.

How can you determine the time elapsed between two consecutive points?

• By using the formula: time = 1 / frequency.

• By observing the puck's velocity.

• By measuring the distance between them.

• By counting the number of points.

Which point can be chosen as the origin for data analysis?

• The first point.

• Any point, since the velocity is constant.

• The last point.

• The midpoint of the data set.

What is the significance of the slope in the position-time graph?

• It represents the time taken for the experiment.

• It shows the frequency of the spark timer.

• It indicates the distance covered by the puck.

• It corresponds to the velocity of the puck.

What is the purpose of plotting the data on a position-time table?

• To determine the frequency of the spark timer.

• To find the time taken for each point.

• To visualize the motion and calculate the velocity.

• To check if the table is inclined.
