# [Phys-l] e: (Possibly Useful?) Physics Video Clips

Some how an extra two characters "3D" became inserted in each link.

Try these:

I tried to view the 3 videos below and got a Youtube site message that the
videos were not available.

I have started collecting video clips taken with my vid camera and my cell
phone, for use as examples in my physics classes. If anyone is interested,
please feel free to use any of the following:

1. A Toyota hybrid (mine) being towed up a tow truck ramp. Actual values for
car mass, ramp angle, and coefficient of rolling friction are given in the
video comments. Forces can be labeled, divided into components, and the
tension in the tow cable calculated. (For those doing torques, the diameter
of the winch roller was about 10 inches).

2. The cart for a county fair "Tractor pull", showing the weighted box being
lowered back into position for the next contestant. (Explanation of how the
cart works is provided in the video comments section)

3. A tractor entered in the tractor pull event. Shows the tractor pulling
the cart. The rise in the weighted box is visible., Video notes describe how
this increases the force of kinetic friction, opposing the tractor's motion,
the farther the tractor pulls. http://www.youtube.com/watch?v=3DkAus_TVKzbM

If there is interest in sharing any of these 'real-life physics' examples, I
will be posting more. I have some video clips I captured of different fair
rides, which may be useful for calculating how acceleration and number of
g's experienced change in circular motion. There are also many
many of which show vectors for velocity, which can be readily related to
conservation of energy and conservation of momentum.
