If you were challenged and were correct, you get 50 pts If you were challenged and was not correct, the team that challenged you gets 100 pts. Gravitational Force Magnetic force (Attractive forces accepted if you do not give either of the two above) Centripetal Answer to forces 50 Board
Calculations for 10 pts: How do I calculate for work? A
Answer to calculations 10 Work = Force in Newtons x distance in meters Board
Calculations answer for 20! Free square = free points!! So stand at the right time….. board
Calculations for 30 pts.: What units are Work measured in? Write it on the board…. A
Calculations answer for : 30 pts! Work= Nm board
How would I calculate for work output? From Calculations for 40 pts. Switcheroo !! A
Work Output = load force divided by effort force If you got this right you may choose any table to switch the current table score with. If you got this wrong you do not switch, but if a reasonable attempt made you may have 20 pts. board Calculations answer for 40 pts.
50pts: Calculations for 50pts: How would I calculate for Input work? Answer
If right, you earned not 50 pts., but 100 pts! board DOUBLE JEOPARDY!! Work Input = Effort distance divided by load distance 50 pt. calculations
Mixed bag for 10 What type of lever is the following: A
Mixed Bag Answer for 10 Third class lever Board
Mixed bag for 20 pts How do we know the question about a machine is talking about a fake machine? (according to the data…) SURPRISE JEOPARDY!!! Board
Answer to mixed bag 20 (SURPRISE!!! EARN DOUBLE YOUR SCORE if right!! ~ if you started with 0 and got this right, go to 300) ANSWER -- If we look at the work output and the work input, a real machine would have friction, so work output number is LESS than the work input number.
Mixed bag for 30 What does Inertia mean and which Law is it? A
Mixed Bag Answer for 30 In Newton’s First Law An object at rest will remain at rest, an object in motion will remain in constant motion, unless acted upon by an unbalanced force. Board
Mixed bag for 40 Read the following and tell me agent of force (Causing it), receiver of force, what happens and what the force is called: A 10-speed bike brake is pushed and the bike stops.
Answer to m. bag 40 If correct, switch with another and add 80 pts. Not correct, means no switch and no double jeopardy! –agent of force (Causing it) : brake –receiver of force : tire (or 10-speed) –what happens : bike stops –what the force is called: friction Board
Mixed bag for 50 Explain the big idea on how all simple machines effect the work that is done on an objectExplain the big idea on how all simple machines effect the work that is done on an object
Mixed Bag Answer for 50 DOUBLE JEOPARDY!! EARN 100 A simple machine will reduce effort force needed and increase effort distance. (Work done on the object stays pretty much the same.) Board Extra for group: Which simple machine reduces effort the most?(5 pts) And why? (10 pts)
