Chapter 2 & 3 – Motion
and Projectile Motion UNIT
Objectives
- Explain the idea that
motion is relative.
- Define speed and
distinguish between instantaneous speed and average speed.
- Distinguish between speed
and velocity, and describe how to tell whether a velocity is changing.
- Define acceleration and
give examples of its units.
- Describe the motion of an
object in free fall.
- Describe the motion of an
object thrown straight up and allowed to fall until it hits the ground.
- Determine the speed and
the distance fallen at any time after an object is dropped from rest,
when air resistance is negligible.
- Explain how graphs can be
used to describe relationships among time, distance, and speed.
- Describe how air
resistance affects the motion of falling objects
- Explain why acceleration
is a rate of a rate.
- Distinguish between a
vector quantity and a scalar quantity, and give examples of each.
- Draw vector diagrams for
velocities. And use the parallelogram method to find the resultant of
two vectors that have different directions.
- Given a vector, resolve
it into horizontal and vertical components.
- For a projectile,
describe the changes in the horizontal and vertical components of its
velocity, when air resistance is negligible.
- Explain why a projectile
moves equal distances horizontally in equal time intervals, when air
resistance is negligible.
- Describe satellites as
fast moving projectiles.

diagrams of a fast toy car and a slow toy car differ? (You could
choose other objects.)
2. What factors affect
the speed of an object down a ramp?
- What factors affect the
path of a projectile?
- Activity 53 on page
27. Describe your methods and show all data and calculations.
Select another student and find their hang time as well.
5. Select another
experiment. Get approval before starting.
A Layer – (Choose one – 20
points)
- The study of various
motions in nature requires devices for measuring periods of time.
Prepare a presentation on a specific type of clock such as water
clocks, sand clocks, pendulum clocks, wind up clocks, atomic clocks, or
biological clocks. Who invented or discovered the clock?
What scale of time does it measure? What are the principles or
phenomena behind each clock? Can the clock be calibrated? –
Research the clock and provide references.
- Watch a videotape of a
football kickoff. Measure the time of flight and note the
starting and ending yard lines. Calculate the initial horizontal
and vertical velocities, the initial velocity, and the maximum
height. Select another sport in which projectile motion is
evident (such as golf or soccer.) Analyze the motion of the
projectile and compare the motion of the two objects. – Be sure
to include all data and calculations. Make a report or display
sharing your results.
- Select another topic.
Get approval before starting.
