Newton’s 2nd LawDecember 9th & 10th

Do Now Take a Snowman Venn Diagram – 12 points! (2 points per empty space –

must be complete & correct to earn credit) Turn in Boxed Questions (your HW)

HW: Over the next 2 days, look for AS MANY SCENARIOS AS YOU CAN

where Newton’s 1st and/or 2nd Laws apply. Be ready to discuss them next class for an activity.

FINISH today’s Math Practice problems. They will be posted on my website. We are playing a game using them next class.

Ensure that the boxed questions are COMPLETELY DONE and CORRECTED. We are playing a game using them next class.

Start preparing for test on Ch. 4-5-6… Dec. 17th (A) & 18th (B) Study Guides will be online by tomorrow; hard copies on Wed.

Extra Credit opportunity – medicine drive for Dominican republic

Extra Credit Opportunity: For the Newton’s Laws Test … Dec. 17th (A) & 18th (B) EXTRA CREDIT: Medicine drive for Dominican republic

DEADLINE OF DECEMBER 16. Mrs. Bella’s Daughter is collecting Medicine for

a Mission Trip to the Dominican Republic. Medication needed is on the collection box;

feel free to take a picture. If 50% of the class brings in item(s), the whole

class will receive 1 extra credit question on the test.

75% of the class = 2 extra credit questions. 100% of the class = 3 extra credit questions.

ALSO - For every 1 item you bring in, you will receive 1 additional extra credit question on the test. Maximum of additional 10 questions.  

Collection Items include the following:

Collection items include brand name & generic versions of the following: Tums, Benadryl, Ibuprofen (Advil, Motrin), Naproxen (Aleve), Chewable Kids Tylenol, Antibiotic Ointment (Neosporin), Antifungal Cream, Hydrocortisone cream, artificial tear drops (NOT contact solution!) Adult Multivitamins, Prenatal Vitamins, Children Vitamins ( NOT gummy) Iron Supplement (325 mg), Pepcid, Biscodyl

Today’s Tasks #14-15 from MILLIONAIRE – we are going over them

together.› Know how to do them? Review Boxed Questions w/group

Groups review of Boxed HW questions Start tonight’s HW if time provides.

› CHECK IN with a teacher if you need HELP or CLARIFICATION!

Last 5 minutes of class are an exit slip!› #14 - A crate has a mass of 10kg. You personally pull with a force of 10N, but

the force of friction is 4N. Suppose the crate is already moving at 1m/s. How fast will it be moving after you have pulled it for 10 seconds?

› #15 - A 1000 gram toy car is moving at 1m/s, and eventually slows to 0.2 m/s in 4 seconds. If 5 N of friction act on the car, how much force is the car applying to make itself move?

Then, meet with groups of your choosing to review the Boxed HW questions, and start tonight’s HW if time provides. › CHECK IN with a teacher if you need HELP or

CLARIFICATION! Last 5 minutes of class are an exit slip!

Today’s Tasks #24 – see HW solution (we did this already)#25…No…you can only conclude that no NET force acts on it#27….as you burn fuel, you lose mass…less mass, more

acceleration!#28…1N in the direction opposite to push#35…. Still 1 m/s2#36….4 m/s2#37…. 2x mass = ½ the acceleration….so 1.5 m/s#38…Net F = 0….Friction = 100 N opposite to push#39… ¾ the force means ¾ the acceleration… so 1.5 m/s2CHALLENGE #1 – Mass = 2000 kg, weight is approx. 4400 pounds; 19,600 NCHALLENGE #2 – F = approx. 1818 N (first, solve for acc. Then, convert lb kg…

Then, F = ma)
