Ch 3: Kinematics (Princeton Review)

Question 1

If you are answering a question which uses the word “circuit” and asks about displacement, what should you recall?

Answer 1

Completion of one circuit implies a net zero displacement!

(Example: a red blood cell pumped through the body)

Question 2

What is the formula for average velocity?

Answer 2

Displacement / time

Question 3

In contrast to velocity, what is the formula for average speed?

Answer 3

Total distance traveled / time

Question 4

What is the formula for displacement?

Answer 4

Final position - initial position = net distance

p. 51

Question 7

Which of the Big Five equations excludes v_f?

Answer 7

d = v₀t + ½at²

Question 8

Which of the Big Five equations excludes v₀?

Answer 8

d = v_ft - ½at²

Question 9

Which of the Big Five equations excludes t?
