Forces
A force that draws objects down is...
gravity
What is filament?
Plastic that goes into the 3D printer
In the equation F=ma, what does F stand for?
Force
What is the plastic that let the rocket go slowly down to the ground called?
parachute
What is trajectory?
the path of an object
What is the bottom of the printer (the part that the piece gets built on) called?
bed
What was happening with the Newton's Towers (the paper boxes that we tried to get the bottom one out without making the other ones fall)
When we move the box quickly, the speed overcomes the frictional force, which allows us to move the bottom one out without the top ones falling.
What are the three parts to the rocket?
nose, body, fins/tail
What is thrust?
Force pushing something forward
What is a type of filament that is used?
PLA, ABS, TPU, PETG/PET
What is Newton's first law?
an object at rest remains at rest and an object in motion remains in motion unless an outside force acts on in.
How did we launch the rockets (list the steps that we went through on launch day)?
put engine + ignitor into rocket, put clips on metal part of ignitor, count down, and hold down the button!
What type of force is air resistance?
Drag force
What is the extruder on the printer?
Part that the heated up filament comes out of
What is Newton's third law?
for every action, there is an equal and opposite reaction
What is the string like thing that connected the nose/parachute to the tail of the rocket?
Shock cord
If an object has equal thrust and drag force, and there are no other forces acting on the object, which direction, if any, is the object moving?
not moving
What is the layer of filament that goes under pieces that aren't touching the printer bed well called?
Brim
What is Newton's second law?
Force = mass times acceleration
What is the paper like thing we put in the rocket so the parachute didn't melt?
recovery wadding
