Task 3.

Task 3: Vertical and Horizontal Velocities of a Projectile Motion! Instruction: 1. Prepare materials such as marble/ small ball with talc [babyr powder], tape measure, and timer] stopwatch and follow a setup below. 1" Ball covered with talc r' Height of the table Extended tape measure 2. Hold the ball at the height exactly the height of the table . Release the ball and start the timer simultaneously , then stop the timer when the ball hits the oor. Record the time. 3. This time, put the ball near the side edge of the table as shown in the set-up above. Slightly push the ball horizontally so that it will move in a pro- jectile trajectory. Start the time the moment the push hits the ball, then stop the time the moment it hits the oor. Record the time and measure the dis- tance [range] of the ball from the base of the table [consider nearest baby pow- der mark on the oor from the base of the table 1. 4. Do the #3 procedure but with increased horizontal push. Record the time and measure the distance [range] of the ball from the base of the table [consider nearest baby powder mark on the oor from the base of the table ]. Refer to the figure above. 5. Do #2 to #4 procedures in three trials. Record the data gathered . Table 2.

What can you say about the horizontal velocity of a projectile motion [ assumed that air resistance is negligible]? '2. What can you say about the vertical velocity of a projectile motion [ assumed that air resistance is negligible]? 3. What makes the vertical velocity independent to a horizontal velocity of a projectile motion? 4. What quantity/ies do you think is/are common between the vertical and horizontal component of projectile motion
