First Quarter Categories

Precision and Accuracy Upward Launches Metric Prefixes Acceleration

Page 3: Physics Team Trivia!

Precision and Accuracy

Student A measures a distance to be 4.3 meters and Student B measures the same distance to be 4.32 meters. Student A is:A. Less preciseB. Less accurateC. Both less precise and less accurate.D. Neither less precise nor less accurate.

Page 4: Physics Team Trivia!

Precision and Accuracy

A. Student A is equally as accurate but less precise, measuring only to the nearest tenth of a meter.

Upward Launches

An object is launched upward at +5m/s. What is its acceleration at the peak of its flight?

Page 6: Physics Team Trivia!

Upward Launches

-9.81 m/s2

Page 7: Physics Team Trivia!

Metric Prefixes

What metric unit is 100,000 larger than a centimeter?

Page 8: Physics Team Trivia!

Metric Prefixes

A kilometer

Page 9: Physics Team Trivia!

Acceleration

What is the acceleration of an object traveling at a constant 4 m/s for 3 seconds?

Page 10: Physics Team Trivia!

Acceleration

0 m/s

Second Quarter Categories

Significant Figures Acceleration Free Fall Variables

Page 13: Physics Team Trivia!

Significant Figures

The dimensions of a room are 14.3 m by 6.2 meters. What is the area of the room with significant figures?

Page 14: Physics Team Trivia!

Significant Figures

Page 15: Physics Team Trivia!

Acceleration

What is the acceleration of an object traveling to the right whose speed is decreasing by 5 km/h every second?

Page 16: Physics Team Trivia!

Acceleration

-5 km/h/s

Page 17: Physics Team Trivia!

Free Fall

Assuming no air resistance, which, if either, will fall faster: a brick or a feather?

Page 18: Physics Team Trivia!

Free Fall

Neither. In a vacuum, all objects fall at the same rate.

Page 19: Physics Team Trivia!

Variables

A student decides to see if there is a relationship between how loud his music is and how fast he drives as a result. Name the independent and dependent variables.

Page 20: Physics Team Trivia!

Variables

Independent: how loud the music is Dependent: how fast he drives
