What must occur every time for work to be exerted?

A 100


  • A force must be applied

  • An object must move in the same direction as the force

A 100


  • What unit is used to measure force?

  • What unit is used to measure work?

A 200


  • Newtons (N)

  • Joules (J)

A 200


What is the formula for work?

A 300


Work = force x distance

(W = f x d)

A 300


If you lift your science book up off the floor, are you doing work?

Why/why not?

A 400


Yes, because you are lifting your books upward, and the books are moving upward also.

A 400


You pick your cell phone up off the counter and talk into it as you walk across the room. When you finish talking, you place it back on the counter and slide it away from the edge.

When are you doing work on the cell phone?

A 500


  • Picking up the cell phone

  • Placing it down on the counter

  • Pushing it away from the edge

A 500


You exert 20 N to push a desk 10 m.

B 100


200 J

B 100


You move a wheelbarrow

50 m by exerting 100 N.

B 200


5,000 J

B 200


What is the MA of a machine that has an output of 250 J if you have an input of 10 J.

B 300


25

B 300


You push a car 0 m with 200 N

B 400


No work is being done because the car didn’t move

B 400


You carry your cat 50 m with 100 N

B 500


No work is being done, you are holding the cat up and moving it forward

B 500


What is a term that means the same thing as input force?

C 100


Effort

C 100


OL-What is the ideal mechanical efficiency of a machine?

AD- How do you calculate the mechanical efficiency of a machine?

C 200


OL-100%

AD- output force

input force

x 100%

C 200


How do you find the MA of a machine?

C 300


Output force

Input force

C 300


What are the 3 ways a machine can help you do work?

C 400


  • Multiply distance

  • Multiply force

  • Change direction

C 400


What is the MA of a machine that multiplies force?

C 500


Greater than 1


An inclined plane that moves is called?

D 100


A wedge

D 100


An inclined plane wrapped around a cylinder is called?

D 200


A screw

D 200


A machine that uses 2 or more simple machines is called?

D 300


A compound (or complex) machine

D 300


  • Which type of simple machines best represent these parts of your body?

  • Muscles and bones

  • Teeth

D 400


  • Levers

  • Wedges

D 400


Why would you increase the length and thinness of a wedge?

D 500


To create a greater MA

D 500


The fixed point a lever pivots around is called?

E 100


The fulcrum

E 100


The weight the lever lifts is called?

E 200


The resistance

E 200


What is always located in the middle of a 2nd class levers?

E 300


The resistance

E 300


What class of lever does a bottle opener belong to?

E 400


2nd class

E 400


What class of lever do pliers belong to?

E 500


1st class

E 500


From an element’s location on the periodic table, what can you predict?

F 100


An element’s properties

F 100


What is used to measure how much matter an object contains?

F 200


Mass

F 200


When elements are in the same column on the periodic table, they are in the same _________.

F 300


Family

F 300


How are atoms and elements related?

F 400


Every element has it’s own specific type of atom.

F 400


In order for a skater to not be accelerating, what would they need to be doing?

F 500


Skating in a straight line at a constant speed.

F 500


The Final Jeopardy Category is:

Types of Machines

Please record your wager.

Click on screen to begin


  • OL- Explain why wedges and screws are actually types of inclined planes.

  • AD-

  • If constructing a lever with the highest MA possible, where should the effort, resistance, and fulcrum be located?

  • Using the picture below, which machines multiply the input force?
