Review of November 4
Passed back vocabulary test
Saw video on drag racing
Prepared for drag race lab,
but due to behavior issues, did
not complete it. OR Set up and ran drag race lab

Topic/Objective:
Name:
Friction
Class/Period:
Date: Nov 7,
2016
Essential Question: Demonstrate
your knowledge of the 4 types of
friction by getting all correct on a
warm up.
1. What is this formula used to
identify?
v=d/t
Answers: a) Acceleration; b) velocity;
c) speed
2. What is this formula used to
identify?
speed plus direction
(d/t with direction)
Answers: a) Acceleration; b) velocity;
c) speed
3. What is this formula used to
identify?
v=speed, t=time
V2-V1
T2-T1
Answers: a) Acceleration; b) velocity;
c) speed
4. What is the acceleration rate of
this motorcycle? V1=0; V2=10km/s;
T1=0; T2=5 SECONDS
V2-V1
T2-T1

V2-V1
T2-T1
Answers: a) Acceleration; b) velocity;
c) speed
4. What is the acceleration rate of
this motorcycle? V1=0; V2=10km/s;
T1=0; T2=5s
V2-V1 = 10km/s - 0 = 10km/s
T2-T1 = 5s - 0
= 5s
4. What is the acceleration rate of
this motorcycle? V1=0; V2=10km/s;
T1=0; T2=5s
V2-V1 = 10km/s - 0 = 10km/s
T2-T1 = 5s - 0
= 5s
answer = 2km/s/s

State Standard
1. Newton's laws predict the motion of
most objects.
b. Students know that when forces are
balanced, no acceleration occurs; thus
an object continues to move at a
constant speed or stays at rest
(Newton's first law).
c. Students know how to apply the law
F=ma to solve one-dimensional motion
problems that involve constant forces
(Newton's second law).
State Standards
Friction
a.Students know how to identify separately
the two or more forces that are acting on a
single static object, including gravity, elastic
forces due to tension or compression in
matter, and friction.
