Do Now!

Many of you are missing work. If you have any

work in your locker, book bag, or at home I strongly suggest that you bring it to me ASAP.

I will be returning a lot of graded work today, including speed tests.

Missing Work

The test you took during dispersal two weeks ago.

The grades were horrendous. Only about 5 people had passing grades.

This is part of your test on Friday. Every student will have to retest on Wednesday.

We will review the test today in preparation.

In addition, I will add in parts of Newton’s Laws.

Speed, Velocity & Acceleration Test

Meg and Emi left JMMS at the same time. Meg

lives further away from the school than Emi, but they arrive at their houses at the same time. Compare their speeds.

Question 1

Jaime and Clara are racing. Jaime runs 40

meters in 8 seconds. Clara travels 80 meters 20 seconds. Which runner is the fastest? Show your complete work using the speed triangle and label correctly!

Question 2

Tennessee Titans player, Chris Johnson takes

4.24 seconds to run a 40 meter dash. What is his speed? Show your work on the speed triangle and label.

Question 3

During a NASCAR race a car typically travels

500 miles, going about 180 mi/h. How long would a typical race last? Show your work, and label!

Question 4

What is happening to the speed of this truck

between 6 and 11 seconds?

Question 5

How is acceleration different from speed?

Question 6

What does it mean to have a negative

acceleration?

Question 7

Drew started his race running at 2 m/s, 6

seconds later, he was going 8 m/s. What was his acceleration during the first 6 seconds of the race? Show your work and labels!

Question 8

Drew started his race running at 2 m/s, 6

seconds later, he was going 8 m/s. What was his acceleration during the first 6 seconds of the race? Show your work and labels!

FREEBIE or EXTRA CREDIT

Question 9

Describe the acceleration as positive,

negative, or zero.

Question 10

Question 11

Which of the following represents the velocity of a moving object?a) 40 sb) 40 m northc) 40 m/s2

d) 40 m/s north

Question 12

Which of the following represents the acceleration of a moving object?a) 40 sb) 40 m northc) 40 m/s2

d) 40 m/s north

Question 13

Which of the following represents the speed of a moving object?a) 40 sb) 40 m northc) 40 m/s2

d) 40 m/s north

Question 14

Which of the following represents the times of a moving object?a) 40 sb) 40 m northc) 40 m/s2

d) 40 m/s north

Question 15

What is Newton’s First Law? Give me an

example of its use.

What is Newton’s Second Law? Give me an example of its use. You need to be able to use the formula for

Newton’s Second law to answer problems.

What is Newton’s Third Law? Give me an example of its use.

Newton’s Laws Test

We will be finishing our foldables from Friday.

You can use this on the test Wednesday as well as the Quarter Final on Friday.

Please do a good job on these and keep up with them. We will only use them if the entire class has them.

Foldables—Finish up from Friday

What is Newton’s First Law? Give me an

example of its use.

What is Newton’s Second Law? Give me an example of its use.

What is Newton’s Third Law? Give me an example of its use.
