Definitions 1st Law 2nd law 3rd law Potpourri

Any push or pull

definitions - $200

force

definitions - $200

The name given to the force that acts between materials

that touch as they move past each other

definitions - $400

friction

definitions - $400

The property of a body to resist change in state of

motion

defintions-$600

a6a

inertia

definitions - $600

The force that is at a right angle to the surface and

opposes gravity

definitions- $800

Normal force

Definitions-$800

The friction acting on something moving through air

definitions - $1000

a10a

Air resistance

definitions - $1000

Every object continues in a state of rest, or of motion in

a straight line at constant speed, unless it is

compelled to change that state by forces exerted

upon it.

1st law - 200

Newton’s First Law

1st law - 200

A measure of inertia

1st law- 400

Mass

1st law - 400

The force of gravity on an object

1st law - 600

weight

1st law - 600

A mother finds that her newborn infant sons weighs 300N, a possible new world record, calculate the boys

mass.

1st law - $800

b8a

30.6 kg (30 kg okay)

1st law - 800

When you compress a junked car into a cube,

which will change, its mass, volume, or weight?

1st law - 1000

volume

1st law - 1000

The acceleration produced by a net force on an object is

directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of

the object

2nd law - $200

Newton’s Second Law

2nd law - $200

Sketch and find the resultant of a 6-N force going left and a

8-N force going up.

2nd law - $400

2nd law - $400

6-N

8-N

10-N

Calculate the acceleration of a 2000 kg single-engine

airplane just before takeoff when the thrust of its engine

is 500N.

2nd law - $600

0.25 m/s2

2nd law - $600

A rocket fired from its launching pad not only picks up speed but also

accelerates as it goes up, why? (HINT: about 90% of the mass initially in a rocket

is fuel)

2nd law - $800

Its mass decreases as fuel is used up. Therefore, the

same force will accelerate it more.

2nd law - $800

A certain force applied to a 2kg mass accelerates the

mass at 3 m/s2. How much acceleration will the same force produce on a 4 kg

mass?

2nd law - $1000

1.5 m/s2

2nd aw - $1000

d2

Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on

the first object.

3rd law- $200

Newton’s Third Law

3rd law- - $200

When swimming, you push the water backward-call this the action force.

What is the reaction force?

3rd law- - $400

The water pushing you forward.

3rd law- - $400

Daily Double

Make a Wager

3rd law- The Daily Double

Why can you exert greater force on the pedals of a bicycle

if you pull up on the handlebars?

Because the handlebars push down on you, and in turn, the

pedals

3rd law-Daily Double

If action equals reaction, why isn’t Earth pulled into orbit around a communication

satellite?

3rd law- - $800

Because of Earth’s much greater mass and inertia

3rd law- - $800

3rd law- - $1000

If a bicycle and a massive truck have a head on

collision, upon which vehicle is the greater impact force? Which vehicle undergoes the

greater change in motion?

The forces are equal but the bicycle experiences a greater

change in motion

3rd law- - $1000

1 kilogram time a meter per second squared is also

equal to this unit

potpourri- $200

Newton

potpourri- - $200

The combination of all forces acting on an object

potpourri- $400

Net force

potpourri- - $400

the ratio of the force of kinetic friction to the normal

force

potpourri- - $600

Coefficient of kinetic friction

potpourri- $600

A bowling ball and a baseball are both dropped from the top of a third floor apartment window, which will hit the ground first?

Which has the greater force of gravity on it?

potpourri- - $800

potpourri- - $800

Both hit the ground at the same time but the

Bowling ball has more force acting on it

gravity

potpourri- - $1000

The force that opposes the movement of two surfaces that are in contact and are

sliding over each other.

potpourri- - $1000

Kinetic friction

Final Jeopardy Category:

The horse and his cart

Make a Wager

Final Jeopardy

A horse is pulling a cart along a path. How can the horse pull the cart if the forces between the

two of them cancel out?

Final Jeopardy

They will move if the force the horse pushes against the ground is greater than

the force of friction
