How can we predict the movement of a one
Dimensional object
What is the relationship between
displacement and motion
An object is in motion
if it changes position
in a certain plane
You are moving past a tree
It looks like the tree is moving
past you but it isn't you are moving
past the tree
When driving down the road and you
pass a semi it looks like the semi is still
but it isn't
What is the relationship
between acceleration and
velocity
They are both related to speed
and when one changes so does the other
When you have a
change in velocity you
have a change in direction.
When you drive down the road
and a deer jumps out in front
you swerve. When you swerve
you slow down
Why do to objects dropped at the
same time and height hit the ground
at the same time
They might have little air resistance
and gravity is pulling down on them
We had to pennies one on the desk
and the other one on a ruler. We knock
both pennies of at the same time to see
which one would hit the ground first.
The one falling straight down was a little
kicker but not by much.
In wrestling when you do a double
leg takedown you both hit the mat and the
same time or pretty close to the same time
