Final Jeopardy


$100 -- Impulse

The equation for

Impulse, solved for

Force


$100 Question: Impulse

What is F = J / t?


$200 -- Impulse

Danny, 55 kg, pushes Jason with a force

of magnitude 600N for 3 seconds.

This is the impulse delivered.


$200 Question: Impulse

What is 1800 Ns?


$300 -- Impulse

A huge truck slams into a tiny VW.

The change in momentum of the

bug-truck system is equal to this.


$300 Question: Impulse

What is bupkis?


$400 -- Impulse

As the magnitude of an unbalanced force

acting on an object increases, the rate of

change of its momentum does this.


$400 Question: Impulse

What is increases?


$500 -- Impulse

A 5-kg cart with velocity of 4 m/s is brought

to a stop in 2 seconds. The magnitude of the

average force used to stop the cart is this.


$500 Question: Impulse

What is 10 N?


$100 – Universal G

It’s a “center-seeking” force or acceleration.


$100 Question: Universal G

What is centripetal?


$200 -- Universal G

It’s how much the force of attraction

between two masses will decrease

If the distance between them is doubled.


$200 Question: Universal G

What is one-quarter of the force?


$300 -- Universal G

This is how many different speedsa satellite may have and still remainin the same orbit.


$300 Question: Universal G

What is one?


$400 -- Universal G

It’s how much the force of attraction

between two masses will increase

if both masses are doubled.


$400 Question: Universal G

What is four times the force?


$500 -- Universal G

It’s how much the force of attraction

between two masses will increase

if the distance between masses is cut by one-third.


$500 Question: Universal G

What is nine times the force?


$100 -- Momentum

The SI unit of momentumand the unit of impulse.(Provide both!)


$100 Question: Momentum

What is kg m/s and N•s?


$200 -- Momentum

An unbalanced force of 25 N is appliedto Alice, 45 kg, for 10 seconds. The change in the magnitude of her momentum will be equal to this amount.


$200 Question: Momentum

What is 250 kg m/s?


$300 -- Momentum

True or false:

The momentum vector always points

in the direction of the velocity vector.


$300 Question: Momentum

What is true?


$400 -- Momentum

A 1000-kg “care package” is fired from a10,000-kg cannon. If the package leaves thebarrel of the cannon with a speed of 500 m/s,

this is the recoil speed of the cannon.


$400 Question: Momentum

What is 50 m/s?


$500 -- Momentum

A 150-N force acts on a 250-kg objectin a direction due east for 10 seconds.

The object is on the planet Zorg, whereg=19.8 m/s2. This will be the change inmomentum on the object.


$500 Question: Momentum

What is 1500 kg m/s due east?


$100 -- Blast from the Past

What a Dum Dum becomes

right after you throw it.


$100 Question: Blast from the Past

What is a projectile

or an object in free fall?


$200 -- Blast from the Past

The magnitude and direction of g.


$200 Question: Blast from the Past

What is 9.8 m/s2 downward or toward the

center of mass of Earth?


$300 -- Blast from the Past

It’s the direction of a normal force.


$300 Question: Blast from the Past

What is perpendicular to the surface?


$400 -- Blast from the Past

Bryan vectors 20m South, West 55m,

North 40m, and then East 55m,

so his displacement is this.


$400 Question: Blast from the Past

What is 20m to the North

or x=20m North.


$500 -- Blast from the Past

The speed of a model airplane that has a

velocity of 12 m/s South with the wind

blowing on it at 5 m/s East.


$500 Question: Blast from the Past

What is 13 m/s?


$100 -- Random Stuff

Number of Ogres in a Megaogre.


$100 Question: Random Stuff

What is 1,000,000 or 106?


$200 -- Random Stuff

Number of donkeys in a teradonkey.


$200 Question: Random Stuff

What is 1,000,000,000,000 or 1012?


$300 -- Random Stuff

The approximate mass of Earth.


$300 Question: Random Stuff

What is 6 x 1024 kg?


$400 -- Random Stuff

It’s what your home electricity meter measures.


$400 Question: Random Stuff

What is energy, or kiloWatt hours,

kWh?


$500 -- Random Stuff

The meaning of the Greek word “phusis”from which our modern word “physics”

is derived.


$500 Question: Random Stuff

What is nature?


Final Jeopardy

  • Jessica, 55 kg, jogs at 4.0 m/s due West.

  • Tyler, 85 kg, jogs at 3.0 m/s due East.

  • This is the vector that describes their combined momentum.


Final Jeopardy Answer

What is 439 kg m/s @ 156o?
