slide2

Solve for t.

2t2 - 3 = 15

2t2 = 18

t2 = 9

t = +/- 3

slide3

Solve for a.

v1 = v0 + at

v1 = v0 + at

v1 - v0 = at

a= (v1 - v0)/t

slide4

Solve for x.

a2 + b2 = c292 + x2 = 25281 + b2 = 625b2 = 544b = 23.3

slide5

Solve for H.

cos q = A/H

cos = A/HHcos = AH = A/ cos

slide6

Solve for x.

sin = O/Hsin(50) = x/15x = 11.5orcos = A/Hsin(40) = x/15x = 11.5

slide7

Solve for y.

y2 + 3y = 10

y2 + 3y – 10 = 0

(y + 5)(y – 2) = 0

y = 2, -5

slide10

What kind of graph would you use to represent the data for the following question:

How does amount of study time affect grades?

Line Graph

(Amount of study time is a continuous variable)

slide11

Match each graph with its slope:

A

B

Undefined

1. Positive

2. Negative

3. Zero

4.Undefined

Positive

C

Negative

D

Zero

slide12

What kind of graph would you use to represent the data for the following question:

How does type of exercise affect pulse rate?

Bar Graph

(Type of Exercise is a discrete variable)

how does the amount of study time affect student test grades
How does the amount of study time affect student test grades?
  • Based on the graph, what average grade would a student receive who studied 2 hours?

88%

slide20

What are the SI base units for length, mass and time?

length = meters (m)mass = kilograms (kg)time = seconds (s)

slide22

Give an example of an uncontrolled variable and a controlled variable from the airplane lab.

Answers will depend on your experiment!!

slide23

Based on scenario 1, on your hand-out:

Identify the Independent Variable and the Dependent Variable.

IV: Age of the grass compost

DV: Height of the bean plants

slide24

Based on scenario 1, on your hand-out:

Identify two controlled variables.

Number of plants per flat, original growth time, amount of fertilizer, amount of sunlight, amount of water, growth time

slide25

Based on scenario 2, on your hand-out:

Identify the Independent Variable and the Dependent Variable.

IV: Types of active metals

DV: Amount of rusting

slide26

Based on scenario 2, on your hand-out:

What kind of graph would be used to display the findings?

Bar Graph

slide28

How can you receive a 10% bonus on your tests in Physics?

Turn in all homework, corrected in red, on or before the test day!

slide29

How do you receive full credit for the homework?

By having it completed on time and showing a genuine effort: a list of variables, a drawing, and equation and an attempt to solve.

slide31

John got a score of 100 out of 5 shots. All the shots were on target. Which targets did the shots land on?

slide32

Fill in the 9 numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9 into the boxes to make the equation correct. Put all the odd numbers on the left and even numbers on the right.

final jeopardy

Final Jeopardy!

If I assigned 1 minute of homework this week, 2 minutes of homework next week, 4 minutes the following week, and continued to double the amount each week until the end of the year, how much homework would you be given the last week (the 36th week) of school?
