Unit Planner
Unit 7: Force and Motion
Lesson 2: Changes in Force and Motion
Time Frame: 5 days
Objectives
Skills: The student will be able to…
• identify and describe the changes in position, direction, and speed of an object
when acted upon by unbalance forces
• calculate average speed using distance and time measurements
• measure and graph changes in motion

6.4A
ELPS:
1C, 2E, 3E
Performance Indicators:
By the end of the unit the student will have learned key concepts:
• Key Concept 1: Potential energy is energy that is stored in a system.
• Key Concept 2: Kinetic energy is energy of a moving object.
• Key Concept 3: Energy can be transformed from potential energy to kinetic energy. Kinetic energy can be
transformed into potential energy.
• Key Concept 4: Energy can be transformed, but not created or destroyed.
Answer Fundamental Questions:
• How is potential energy converted into kinetic energy?
• How do pendulums demonstrate potential and kinetic energy?
Lesson Information
Activities
Engage• STEMscopes demonstration presentation and slideshow. Go
through the presentation and slideshow with students and have
them answer the questions in their science journals.
• With the remaining time introduce the vocabulary. Have
students make their own vocabulary cards using Student
Vocabulary Cards
(There are some words on the template that were not chosen to
be on the vocabulary list.)
• Students can get in groups and use their cards to quiz each other
as to the word meanings as time permits.

Vocabulary
• Position- The Point or area occupied by a
physical object
• Direction- The path that an object is
moving or facing.
• Speed- The measurement of the rate of
change of position with respect to time.
• Force- A push or pull that changes the
motion or position of an object.
• Motion- A change in an object’s position,
direction, or location.
• Distance-Time Graph- A graph that
represents distance traveled in increments
of time.
Process Skills TEKS must be incorporated into
instruction as appropriate throughout the school year.

This can be done in groups to save paper if needed as the packet
is rather long.

•
Balanced Forces- Forces on an object that
do not change the motion of an object.
Unbalanced Forces-Forces on an object
that cause change in the motion of the
object.
Average Speed- Average distance covered
by an object per unit time.
Line Graph- A graph in which the data is
represented by points connected by one or
more lines. It shows change over time.
Evaluate• Students write a short essay describing as best they can the
forces that act upon a baseball as it is a. Thrown by the pitcher
b. Hit by the batter
c. Caught by a player in the outfield
Essays should describe the forces that act on the ball as well as
changes in speed and position (it heads directly over the
pitcher’s mound). Optionally students can draw a distance-time
graph showing the distance of the ball from the pitcher over
time.

Misconceptions/Underdeveloped Concepts
•
•
Students may think that sustained motion requires sustained force.
Students may think if there is no motion, there is no force acting upon an object.
