What angle must you have to make your ping pong ball or golf ball go at least 3 yards on a ping pong catapult?

What angle must you have to make your ping pong ball or golf ball at least 3 yards on a ping pong catapult? First you must know the definition of drag. The definition of drag is resistance to air. (Drag 1). With drag and the golf ball, you have to know do the dimples affect it the answer is yes the air current is affected around it.

(This picture shows the air currents around the balls.)

Even with dimples affecting the air bubble around the ball weight is also an issue because the wind might move it even if its light. And the thing that shows that put a piece of paper on the table on a windy day it moves and after that put a rock on the same table on the same day does it move no. so weight will effect this experiment.

You must also know about air resistance the difference of air resistance is that air resistance is falling object drag is the resistance of air not air resistance. The definition of air resistance is the action of friction that slows something moving through the air.(air resistance 1). The definition of drag and air resistance are similar but they are different too.

4.Ruler
5.Food coloring..maybe..

Type of graph:
Table

Picture of multimedia:
Pictures of experiment and how it happened
Subject of background research: Sound,tones
Purpose: How to or how a water xylophone works and the science behind it.

Enrique---mr rachlin science thing

question: what allows a water Xylophone to make sound

Purpose: to show how vibration works and how music is made

Hypothesis: I think it will make a music

Subject of background research : What allows a water Xylophone to make Diff rent sounds

procedure: put the get the materials needed, water in the bottle, meagre the amount of water that is in the bottle so there isn't a huge amount difference.

materials: Water,glass bottles,drum sticks or a spoon ,chromatic tuner, food coloring optional,

type of graph: line graph

Picture:






obstacles to overcome: not brake the bottles
When you plan to do the experiment: as soon as possible

Question: A bubbling foam bomb

Purpose: What is going to come out of the aerosol can

Hypothesis: I think that i will not be able to see what comes out

Subject of background research:How a foam bomb works

Procedure: Grab the can push it down

Materials: Liquid detergent, vinegar, water, measuring cup, measuring spoons, baking soda, and a funnel with an end that is small enough to fit into the bottle.

Type of graph:Bar graph

Pictures or multimedia:yes

Obstacles to overcome:Might not get it right

not finished

Question: Does swimming with clothes affect or take away energy?

Purpose: I love swimming so i wanted to see what type of things can affect swimming.

Hypothesis: Is that probably most likely that it takes away more energy because the drag make you slow down so you try to put more energy.
