Spinning motion of a
body
A 100
What is rotational
motion?
A 100
The type of motion
experienced by someone in a
Ferris wheel car.
A 200
What is circular motion?
A 200
The velocity of an object
moving around in a circular
path.
A 300
What is tangential velocity
(circular velocity)?
A 300
The direction of the
tangential velocity vector
with respect to the circular
path in which an object
moves (or with respect to
centripetal force acting on the
object).
A 400
What is tangent to the circle? (or
perpendicular to the centripetal
force acting on the object)
A 400
Angular motion is measured
in these units. (There are 2π
of these in a full circle.)
A 500
What are radians (rad)?
A 500
The units of centripetal
force.
B 100
What are Newtons (N)?
B 100
Centripetal force is
directed here.
B 200
What is towards the
center of the circle?
B 200
Racetrack designers make
sure the curves are produced
in this manner to generate
centripetal force needed to
help the cars stay on the path.
B 300
What is banked?
B 300
Acceleration of an object
directed toward the center of
the circular path in which it
moves.
.
B 400
What is centripetal
acceleration?
B 400
The centripetal force needed
to keep the moon orbiting the
Earth is equivalent to this
force.
B 500
What is gravitational
force?
B 500
Torque is a force that
does this.
C 100
What is twist, turn or
rotate an object?
C 100
The tool used to apply torque
to a bolt.
C 200
What is a wrench ?
C 200
Torque depends on two
things: a force, and a
______arm.
C 300
What is the lever arm?
C 300
DAILY

DOUBLE
C 400
The torque lever arm is the
perpendicular distance from
this axis to the direction of
the force applied.
C 400
What is the rotational axis?
C 400
The units of torque.
C 500
What are Newton-meters
or Foot-pounds?
C 500
Scientist developed a
Universal Law of Gravitation.
D 100
Who is Sir Isaac Newton?
D 100
These are two factors of
objects related to their
gravitational attraction for
one another.
D 200
What are mass and distance
from each other?
D 200
The force of gravitational
attraction between two
objects is directly
proportional to this.
D 300
What is mass?
D 300
This is how much the
gravitational force of
attraction decreases as the
distance between two objects
doubles.
D 400
What is by a factor of four?
D 400
6.67259 x 10-11 N m2/kg2 is
the value of this number
associated with calculations
of the force of gravitational
attraction.
D 500
What is G, the Universal
Gravitational constant
(constant of proportionality)?
D 500
The average position of an
object’s mass.
E 100
What is the center of mass?
E 100
Constant tangential speed.
E 200
What is uniform circular
motion?
E 200
The average location of the
weight of an object.
E 300
What is the center of
gravity?
E 300
This quantity measures the
resistance to a change in
rotational motion.
E 400
What is the moment of
inertia?
E 400
This adjective describes the
motion of a body as it shifts
from one point in space to
another. It normally takes
place in straight line.
(Non physics definition:
related to a job of converting
speech from one language to
another.)
E 500
What is translational?
E 500
This helps cause the tides.
F 100
What are the gravitational
forces exerted by the Earth
and its moon?
F 100
This scientist used a torsional
balance to calculation the
Universal gravitational
constant.
F 200
Who is Lord Henry
Cavendish?
F 200
If you swing a ball attached to a
string in a circle above your head,
and the string breaks, this causes the
ball to fly off ’s in a straight line
path.
F 300
What is the ball’s inertia?
F 300
This is said of satellites that
are in orbit around the Earth.
(and causes astronauts on the
ISS to be weightless).
F 400
What is they are in a
continual state of free fall?
F 400
Einstein didn’t believe that
gravity was a force at all, but
a curve or distortion in this.
F 500
What is the shape of spacetime (“fabric of space”)?
F 500
