History
Where was Archimedes from?
Ancient Greece
What is the main force pulling down on the elevator car?
Gravity
Where would an elevator have the most potential energy?
At the top of the pulley system
When was pre-cutting the materials completed? (State day number)
Day 1
What did Elisha Graves Otis invent?
The elevator safety brake
What force is suspending the elevator car?
Force of tension
Where would an elevator in free fall have the most kinetic energy?
At the bottom of the pulley system
True or false: getting the glue to hold sturdily was a challenge for us
True
What is a counterweight?
Object in an elevator that balances (counters) the weight of the elevator car
Which force would change to make the elevator go up? Would it increase or decrease?
Force of tension would increase
Where would an elevator in free fall have the same amount of potential energy as kinetic energy?
In the middle of its track
True or false: We did not change any of our initial dimensions
False
When did Archimedes invent the elevator?
236 BCE
Which force would change to make the elevator go down? Would it increase or decrease?
Force of tension would decrease
How would the energy in an elevator moving at a constant velocity upwards change?
Potential energy would increase; kinetic energy would remain the same
True or false: our group did not have enough pre-cut materials and had to make more
False
What did the first passenger elevators rely on for power?
Steam power
In what kind of situation would there be normal force acting on an elevator car?
When a person is standing inside the elevator, applying normal force downwards (normal force is force from contact between two surfaces)
How would the energy in an elevator accelerating upwards change?
Both kinetic and potential energy would increase
When was the elevator car completed? (State day number)
