Who put the F in Friction?
Potent Potables
1.21 Jigawatts!?
Where’s Big Bertha At? Caw! Caw!
Let’s PARTY-cle physics.
A 100
This is the greater of the two friction forces.
A 100
What is static friction?
A 200
This is the magnitude of the friction force acting on the box above.
A 200
What is 10 N?
A 300
This is the normal force exerted on a 50-N box at rest
on a 30° inclined surface.
A 300
What is 43 N?
A 400
This decreases when a surface gets wet, but stays the
same when the incline or weight of the object changes.
A 400
What is the coefficient of friction (μ)?
A 500
When comparing the force to start a 5-kg wooden object
moving on a wood floor, and the force to keep it moving at
constant speed, this force is greater, and has a magnitude of
this.
A 500
What is the force to start an object moving and 21 N?
B 100B 100
When a bullet is fired from a rifle, the momentum of this is
greater.
B 100
What is neither?
B 200
When comparing the impulse provided by a seat belt/ air
bag to the impulse provided by the windshield, this is
greater.
B 200
What is neither?
B 300
For a given change in momentum, if contact time increases, this decreases.
B 300
What is force?
B 400
When two stationary children on roller blades push off each
other, this and this are the same, but this is different,
because they have two different masses.
What Force exerted and impulse (Δp) stay same, and
velocity is different?
B 400
A 1500-kg car driving 25 m/s east crashes into a 3000-kg car going 25
m/s west on the highway. This is the final momentum of the two cars
after collision, if the cars lock together.
B 500
What is 37500 kg m/s?
B 500
C 100
This is the work required to hold a 50 kg weight 0.5 m
above your head.
C 100
What is 0 J?
C 200
The work required to lift an object straight up is
calculated by multiplying these two specific quantities.
C 200
What is weight of the object and height?
C 300
As time to lift something above your head decreases,
this increases.
C 300
What is Power?
C 400
To determine work from the above graph, you would determine this.
What is area under the curve?
C 400
C 500
Since 400 J are required to lift the weight above with the pulley, this is
the work done against friction. .
What is 40 J?
C 500
In the absence of an electroscope, this is the true
test for charge.
D 100
What is repulsion?

Place A Wager
D 200
When a positive object is grounded, these move from
this to this.
What is electrons move from the ground to the object?
D 200
The leaves diverge more on a positive electroscope when an
object with this type of charge draws near.
D 300
What is positive?
D 300
After experiencing a force F at a distance d from a
spherically charged object, an electron feels this force at a
distance of 3d.
D 400
What is F/9?
D 400
An object with an excess charge of -6 μC is carrying this many extra of these.
D 500
What is 3.75 x 1013 extra electrons?
D 500
In a closed, simple circuit with a cell, one resistor, an ammeter, and a voltmeter, this is how the circuit is
drawn correctly.
E 100
What is ?
E 100
What is ?
To increase the resistance of a metal wire this and this can be increased, and this can be
decreased, respectively.
E 200

sectional area of the wire, respectively?
E 200
In the circuit above, this is the magnitude of V1, VT, I1 and IT,
respectively.
E 300

E 300
This is the equivalent resistance of five 5-Ω resistors in parallel.
E 400
What is 1Ω ?
E 400
Operating at 120 V, this current is required by a motor
to lift a 100-kg object a distance of 10m in 20 sec.
E 500
What is 4.1 A?
E 500
If you lept on a baryon, it would be made of these.
F 100
What is three quarks?
F 100
Multiplied by h, this will give the energy of this.
F 200
What are frequency and photon?
F 200
Losing 3 x 10-3 u of mass results in the creation of this
much of this.
F 300
What is 2.79 MeV of energy?
