Work, Energy, Power and Simple Machines Review

Across
4.	THE ABILITY TO DO WORK
6.	MEASURES THE RATE AT WHICH WORK IS DONE IN A CERTAIN PERIOD OF TIME.
8.	A WHEEL HAS A RADIUS OF 12 INCHES. THE AXLE HAS A RADIUS OF 2 INCHES. WHAT IS THE MA?
10.	_________ PLANE-SIMPLE MACHINE THAT IS A SLOPED SURFACE, OR RAMP.
11.	______ FORCE-FORCE APPLIED TO A MACHINE.
13.	ABILITY OF A MACHINE TO CONVERT WORK INPUT INTO WORK OUTPUT.
17.	_______FORCE-THE FORCE THAT A MACHINE MUST OVERCOME.
18.	INCLINED PLANE WRAPPED AROUND A SHAFT.
20.	STORED ENERGY
22.	THE UNIT OF FORCE
23.	TWO NEWTONS APPLIED OVER 4 METERS.
24.	YOU ARE ABLE TO LIFT A 50 NEWTON BOX 3 METERS ONTO A TRUCK USING A RAMP. THE RAMP ALLOWS YOU TO PUSH THE BOX AT 20 NEWTONS, OVER 8 METERS. WHAT IS THE PERCENT EFFICIENCY OF THE RAMP?
27.	FORCE OUTPUT DIVIDED BY FORCE INPUT.
29.	A SURFACE, SUCH AS A WHEEL, THAT REDIRECTS FORCE USING A ROPE.

Down
1.	________ ADVANTAGE-COMPARISON OF THE INPUT FORCE TO THE OUTPUT FORCE OF A MACHINE.
2.	A FORCE PRESENT IN ALL MOVING OBJECTS; OPPOSES MOTION.
3.	OCCURS WHEN A FORCE IS APPLIED OVER A DISTANCE.
5.	A PULLEY SYSTEM ALLOWS SOMEONE TO LIFT A 100 NEWTON BOX UP 5 METERS WITH 20 NEWTONS OF FORCE. WHAT IS THE MA?
7.	MOVING INCLINED PLANE WITH ONE OR TWO SLOPING SIDES.
9.	THE UNIT OF WORK
12.	THE POINT ABOUT WHICH A LEVER PIVOTS.
14.	YOU RIDE YOUR BIKE 1000 METERS TO TOWN. YOU USE 5 NEWTONS OF FORCE FOR EACH METER. HOW MUCH WORK DID YOU DO?
15.	THE UNIT OF THE RATE AT WHICH WORK IS DONE.
16.	MADE FROM A ROD OR PLANK THAT PIVOTS ABOUT A POINT.
19.	THE ENERGY OF MOTION
21.	________ MACHINE-WORKS WITH ONLY ONE MOTION, SUCH AS AN INCLINED PLANE, LEVER, ETC.
25.	______ MACHINE-COMBINATION OF TWO OR MORE MACHINES.
26.	A PULLEY SYSTEM LIFTS A 10 NEWTON BOX 5 METERS. HOW MANY JOULES OF WORK ARE DONE?
28.	WHEEL AND ____-SIMPLE MACHINE MADE FROM TWO RIGIDLY ATTACHED WHEELS THAT ROTATE TOGETHER.
