Projectile egg target lab
1. Observe and understand motion of a projectile launched horizontally. 2. Apply kinematics equations to data to determine the time of flight, velocity with
which the ball left the table, and the acceleration on the ramp. 3. Use information from part 1, and understanding of physics to predict where the
ball will land when started from a new initial position.
； Piece of angle iron
； Steel ball
； Flat table
； Meter stick
； Carbon paper
1. Set up your angle iron to form a ramp approximately 5cm from the end of the
table. Be sure to set it up in a way that can be exactly replicated tomorrow. 2. Mark a point exactly half way up your ramp. Place your ball on the point. 3. Allow the ball to roll down the ramp, onto the table, off the table and onto the
4. Estimate the landing spot. Tape a piece of computer paper to the floor so that the
center is approximately where the ball landed. Lay a piece of carbon paper on top
of the paper.
5. Set the ball on the half-way point and release 3 more times (Each time make sure
that a team member catches the ball immediately after it hits so that it does not
bounce and land on the carbon paper a second time.). The carbon paper should
mark the location. Measure the distance from a point on the floor directly below
the end of the table to the landing point of the ball. Record this distance as d= __ x
6. Measure and record the height of the table. Record this distance as d =_____ y
7. Give the ball to Mrs. Mann.
8. Draw a free body diagram of the ball just as it leaves the table.
9. What is the net force in the x direction?
10. What is the acceleration in the x direction?
11. What is the net force in the y direction?
12. What is the acceleration in the y direction?
13. Use the free body diagram, your understanding of physics, and the table below to
determine the time that the ball was in the air. Show all formula and substitutions
This page is about the ball leaving the table and traveling to the floor after rolling half
way down the ramp.
14. Use the rest of the information in the table to determine the velocity with which
the ball left the table. Show all formula and substitutions with units!
This section is about the ball rolling along the table after traveling half way down the ramp.
15. Draw a free body diagram of the ball as it rolls along the horizontal table. (It
rolled for such a short distance that friction is negligible.)
16. Based upon your free body diagram, what is the net force on the ball as it rolls
horizontally along the table?
17. What is the acceleration of the ball as it rolls horizontally along the table?
18. With what speed did the ball leave the ramp?
This section is about the ball rolling half way down the ramp.
19. Draw a sketch of the ball on the ramp.
20. Indicate the direction of the net force (You do not need a free body diagram. You
do not need to identify all of the forces acting on the ball).
21. Is the ball a projectile as it travels down the ramp? Why or why not?
22. What is the initial velocity of the ball when it is first released from the point
halfway up the ramp?
23. What is the final velocity of the ball as it leaves the ramp?
24. What is the distance the ball travels on the ramp?
25. What is the acceleration of the ball on the ramp?
26. If the same ball is rolled from a higher location on the same exact ramp, then the
net force acting on the ball will be
c. The same
27. If the same ball is rolled from a higher location on the same exact ramp, then the
acceleration of the ball will be
c. The same
28. Determine the velocity with which the ball will leave the ramp if released from
the top of the ramp.
29. Determine where the ball will land if the ball is released from the top of the ramp,
allowed to roll freely along the table and project onto the floor. Show all formulas
and substitutions with units.
30. Mark the target location, and place an egg on the target.
31. Request your ball.
32. You get one shot for an ice pop.
