UbD : Forces and Motion – Measuring Motion and Newton’s Laws
The process of scientific inquiry to enhance a scientist’s ability to investigate questions and solve problems
Stage 1 – Desired Results
Essential Understanding: Unbalanced forces cause changes in motion that can be predicted
and described.
Established Goals:
• Given opportunities students will be able to experience, observe and describe in words
and pictures motion, including factors of pushing and pulling that create and affect
motion.
• Given opportunities students will be able to experience, observe and describe in words
and pictures motion, Newton’s three laws of motion.
• Make qualitative descriptions of the relationship between forces and motion will
provide the foundation for quantitative applications of Newton’s laws.
State Standards: 12 D: Students who meet this standard know and apply concepts that
describe force and motion and the principles that explain them.
Understandings:
Essential Questions:
Students will understand . . .
• How to represent and describe motion
in a variety of ways.
• The strength of the gravitational force
between objects is proportional to the
mass of the objects the difference
between balanced and unbalanced
forces.
• the application of Newton’s laws in
various situations.
Essential Vocabulary:
• motion
• speed
• velocity
• acceleration
• force (Newton)
• net force
• friction
• gravity
• free fall
• projectile motion
• inertia
• momentum
1.
What are the relationships between
forces and motion?
2. What are the variables that affect
motion and force?
3. How does Newton’s three laws
describe the motion of a moving
object?
4. How does gravity impact objects?
Resultant Knowledge:
Students will know…
• the relationship between speed and
velocity
• the impact of gravity and friction on
motion.
• each of the three Newton Laws
• the impact of the law of conservation
of momentum on the movement of
objects.
Resultant Skills:
Students will be able to . . .

measure and calculate their speed and
acceleration in a variety of situations
assess the impact of force, gravity and
friction on objects
site examples of net force and balance
forces.
design and conduct investigations
involving the motion of objects
justify which of Newton’s Laws is
evidenced in a variety of examples.
Stage 2 – Assessment Evidence
Performance tasks.
¾ Compute speed and acceleration of
moving objects
¾ Create graphs of moving objects speed
and acceleration.
¾ Identify the presence of forces in real
life scenarios: speed, acceleration,
friction, air resistance and gravity.
¾ Demonstrate the involvement of
Newton’s Laws in everyday situations.
Other Evidence.
¾ Multiple Choice assessment on key
formulas and terms
¾ Completion of math computations
¾ Presentation of Newton Law
Project with evidence cartoon
images demonstrating each of the
laws.
