Work is equivalent to these
forms of Energy.
A 100
Kinetic and Gravitational
Potential Energy
A 100
Is work being done in all of the
following situation (if not, in
which situation is work not
done)?
Pushing a crate, lifting a crate,
holding a crate above your
head,
A 200
Holding the crate above
your head—there is no
displacement.
A 200
What is a unit of work?
A 300
The Joule
James Prescott Joule
A 300
Is work a scalar or a
vector quantity?
A 400
It is a vector quantity. It has
both magnitude and direction.
A 400
If you are carrying a crate
from one place to another, are
you doing work?
A 500
No
A 500

How is energy defined in
Physics?
B 200
The ability to do work.
B 200
What term refers to the
sum of kinetic energy
and all forms of
potential energy?
B 300
Mechanical
energy
B 300
What form of energy is
related to an object’s height
above a baseline position.
B 400
Gravitational potential energy
B 400
What energy change occurs
as a roller coaster car moves
from the top of a hill to some
point down the hill?
B 500
Potential energy is begin
converted to kinetic energy.
B 500
How is momentum
defined?
C 100
Momentum is the product
of mass and velocity
C 100
What is an impulse?
C 200
Impulse is equivalent to a
change in momentum.
C 200
What is the Conservation of
Momentum?
C 300
The total momentum of all
objects interacting with one
another remains constant
regardless of the nature of the
forces between the objects.
C 300
DAILY
Please no wagering.
DOUBLE
C 400
What in conserved during a
perfectly elastic collision --momentum, kinetic energy, or
both momentum and kinetic
energy?
C 400
Momentum and kinetic energy
are both conserved.
C 400
What in conserved during a
perfectly inelastic collision --momentum, kinetic energy,
or both momentum and
kinetic energy?
C 500
Momentum is conserved but
there is a loss of kinetic energy.
C 500

tangential velocity?
D 100
Circular velocity
D 100
What force maintains an
object’s motion in a circular
path?

E 300
Is the gravitational force of
attraction directly or inversely
proportional to the distance
between bodies.

Inversely proportional
E 400
Who explained that a planet
maintains its orbit around the
sun due to a distortion of the
fabric of space-time.
E 500
Who else but Albert
Einstein!

What factor influences the
period of a pendulum bob on a
string, the angle release, the
length, or the mass of the bob?
F 300
Length
F 300
What is the quantity that
measures the ability of a force
to rotate an object around
some axis?
F 400
Torque
F 400
What is the average position
at which the gravitational
force acts on the body?
F 500
Center of Gravity
F 500
The Final Jeopardy Category is:
Friction
Please record your wager.
Click on screen to begin
The relative roughness of the two
surfaces indicated by the coefficient of
static friction of the surfaces (us), is one
factor that influences maximum friction
force, what is the other major factor.
Click on screen to continue
The magnitude of the contact force
between the object and the surface on
which it rests. The larger the contact
force (normal force), that harder it is to
make the object start sliding.
