Performance Task

Application of all Concepts and Skills Learned Through An Experiment

Competency 9: Conduct Performance Task

PERFORMANCE TASK: Experiment on Newton’s First Law of Motion

I. Objective: Explain Newton’s First Law of Motion

II. Materials: ball, clearly-marked target (i.e., notebook paper, tape or pal), tape measure or ruler

III. Procedure:

Mark the starting line A and place a target about 10 meters away from it (C). Mark B about 1m before the target and mark D 1 m after the target.
With the ball in your hand, you are about to sprint towards the target respectively, and to drop the ball on the target. Record your predictions in the table.
Hold the ball and do not let your elbow leave your side as you sprint toward the target and drop the ball. Do not give the ball an initial velocity; hold the ball from its sides so that you can release freely your grip as you let it drop.
Record where the runner released the ball and where the ball strikes the ground.
Draw the best diagram for each attempt to drop the ball on the target. Specify where the ball was released and where it landed.
Repeat the experiment until the ball hits the target.
Repeat 2 but this time, do not sprint just run at a slower speed.
Repeat 2 but at walking speed.
