Objective:
SWBAT demonstrate the relationship between force and changes in velocity by completing the “Changes in Motion” lab
Do Now:
Question 1
1.
How can the motion of a soccer ball that is moving come to a stop? How much force
must be applied if it is moving with 10 units of force to the right?
A soccer ball that is moving 10 units to the right can stop if…
Guided Practice: Energy
Amplify Science:
Unit 2: Force and Motion
Chapter 1: Force and Velocity
Lesson 1.3: Investigating Direction of Force
Simulation
Question 2
2.
What do the 3 bars on the top left allow you to do?
Explore more missions
Log out of the simulation
Change the mission settings
Question 3
3.
What are the different masses of the objects you can use in the simulation
.25 kg
.50 kg
1 kg
2 kg
4 kg
20 kg
Question 4
4.
If you click on the center of one of the objects what are you able to change?
Horizonatal and vertical velocity
Mass and weight
Force applied
Question 5
5.
What is the initial speed/velocity of an object if it is
not moving
?
0 m/s
10 m/s
100 m/s
Data Collection:
Build: Initial velocity
Run: Apply force
Analyze: Replay
Question 6
6.
Complete the table below identifying how you made the objects change velocities. Use the key below to help you fill in the chart.
Identify initial velocity and create that in the simulation
Identify the change that needs to happen, identity the force applied

Question 7
7.
Independent Variable (IV):
The cause of the change/result
Direction of force
Change in speed/velocity
Mass of object
Question 8
8.
Dependent Variable (DV):
The effect based on the change
Direction of force
Change in speed/velocity
Mass of object
Question 9
9.
Constant Variable:
Stays the same
Direction of force
Change in speed/velocity
Mass of object
Independent Practice:
Question 10
10.
Draw an arrow on the correct line and in the correct direction that will indicate that a force is added to make
Object A move faster
.

Question 11
11.
Why does Object A move faster when you applied a specific direction of force rather than another directional force?
CFS:
Accurately identifies applied forces by analyzing the movement of objects
Accurately describes how changing independent variables (force) impact the outcomes in testing
Question 12
12.
Draw an arrow on the correct line and in the correct direction that will indicate that a force is added to make
Object A move slower or stop
.

Question 13
13.
Why does Object A move stop when you applied a specific direction and amount of force rather than slow down or change direction?
CFS:
Accurately identifies applied forces by analyzing the movement of objects
Accurately describes how changing independent variables (force) impact the outcomes in testing
Exit Ticket:
Analyze the data table below and answer the questions below.
Question 14
14.
What is required of an impact force in order to
cause an object in motion to stop
?
CFS:
Accurately identifies applied forces by analyzing the movement of objects
Accurately describes how changing independent variables (force) impact the outcomes in testing
