Transcript Activity 5 Basketball
Basketball and Gravity
Objective: Students will apply
what they have learned about
gravity and free falling objects
to the sport of basketball.
What is Gravity???
Force
that exists between any
two objects that have mass.
Gravity is the pulling force
(pulling towards the center of
the Earth or the force pulling
objects together).
Gravity and Basketball
Where
do you aim a basketball
when taking a free throw?
Do you aim toward the rim, the
backboard, or the basket?
Toward the basketball or the
backboard
Activity
You
will work in groups of 4
Your group will work on steps 1 and 2
of the activity sheet.
Group # is identified by the index card
on your desk.
Every member needs to participate in
the activity.
Read over Steps 1 and 2
10 – 15 minutes will be given for this
What does the path of the ball
look like?
What causes the ball to fall?
GRAVITY
Free Throw
When
you shoot a free throw the
path of the ball is an arc.
Gravity causes the ball to fall as it
travels.
Parabola is the term used for the
arc created by the act of gravity
on the basketball.
Activity
Continue
with step #3
Students should throw until
each member of the team has
made a basket directly and as a
banked shot.
10 – 15 minutes will be given
for this activity.
How are the two paths of the
tossed balls different?
Tossed Basket
Banked Basket
Space Basketball
What
would be different in playing
basketball in space?
Astronauts would not be able to
make shots that require arcs.
Arcs are impossible in space
because of the free fall
environment.
Free Fall
What is this?????
Free
fall is motion with no
acceleration other than that
provided by gravity.
Free fall is experienced in
space or on the shuttle.
Space Background
Astronauts in the space shuttle are seen
“floating” about with no floor to stand on.
The same gravity force that keeps you in
your chair also keeps the astronauts, and
the Moon, in orbit.
If Earth’s gravity were turned off, orbiting
astronauts, and everything else held by
Earth, would fly off into interplanetary
space.
Why do objects float in space?
The
shuttle is falling toward Earth
just as you would be if your chair
suddenly broke.
The shuttle is traveling so fast that
Earth curves away from it as it falls.
Floating is due to falling in
space…….8 km/sec or 5 miles/sec
Step 4
Now imagine playing basketball while
circling Earth in the space shuttle. The
spacecraft and the astronauts are falling
around Earth at the same rate. As a
result, everything inside the shuttle seems
to float.
Predict: Could an astronaut make a
banked shot in space?
Could an astronaut toss the ball directly
into the hoop?
What kind of trick shots could an astronaut
make?
Homework
Find
one example in your daily
lives in which you use the arc
of a falling object to complete
the task……
