Research Question:
How do roller coasters use energy to work?
Directions
:
1.
Watch
the video about roller coaster physics.
2.
Answer
the questions that follow.
Question 1
1.
What is
potential
energy?
heat energy
total energy
motion energy
stored energy
Question 2
2.
How does a roller coaster
get
potential
energy?
Going uphill
Going downhill
It always has potential energy
Being pulled uphill by a machine
Question 3
3.
How can you
increase
a roller coaster's
potential
energy?
make it move faster
make its hill taller
make its hill shorter
make it move slower
Question 4
4.
Question 5
5.
What is
kinetic
energy?
stored energy
motion energy
total energy
heat energy
Question 6
6.
How does a roller coaster
get
kinetic
energy?
Going uphill
Question 7
7.
When does a roller coaster have its
greatest
amount of
kinetic
energy?
At the top of the first hill
At the bottom of the first hill
At its fastest speed
At its slowest speed
Question 8
8.
Why does a roller coaster
slow down
as it goes
uphill
?
Gravity acts against the cart
The cart is losing potential energy
The cart loses energy
Question 9
9.
When does a roller coaster's
kinetic energy
turn back into
potential
energy?
As it goes downhill
As it goes uphill
Never
Question 10
10.
Friction (resistance) between the track and the cart's wheels cause a lot of the cart's energy to convert into ___.
gravity
heat energy
kinetic energy
potential energy
Question 11
11.
How can you
increase
a roller coaster's
speed
?
Increase its potential energy
At what point does a roller coaster cart have its
greatest
amount of
potential
energy?
At the start of the ride
Going up the first hill
At the top of the first hill
Going down the first hill
At the bottom of the first hill
At the top of any hill
At the highest point during the ride
Going downhill
It always has kinetic energy
Gravity and momentum
Converting from potential energy
Increase the cart's mass
Increase the height of drops
Add passengers to the cart
Increase friction between the cart and track
