Physical Science Assignment #5
Open
the page here in a new window to do the following:
- Try the first animation.
After the car hits the wall in what direction, if any, is it accelerating?
In what direction, if any, is the driver accelerating?
- Now try the second
animation. In what direction, if any, are the truck, the car and the ladder
each accelerating?
Open
the page here in a new window to do the following:
- What is inertia?
- Scroll to the bottom and
answer the practice questions there.
Open
the page here a new window to
do the following:
- Look at the first three diagrams
of the textbook and man. These are
called free-body diagrams. Try
doing a free-body diagram of you yourself at this moment. Remember to identify each of the forces
acting on you.
- Try the practice questions
at the bottom.
If you are done early you can go here
to learn about forces on airplanes, or here to look at
forces on bridges. Or continue reading through the physics lessons by clicking
on “Next” at the bottom of the page in the pages you looked at for
questions 1 to 6.
