Motion in 1-D reference
Maybe instead of referring folks to the menu, you could just link the concepts of acceleration and velocity to the 1-D page?

Vectors
I'm not sure what you mean by the bold face vectors statement in the middle of the page. Maybe you could clarify it?

gravitational field
The acceleration due to the gravitational field shouldn't be confused with the force field itself. The force of gravity causes the objects to accelerate at 9.81 m/s^2. Another way to say it might be, "the acceleration due to gravity is 9.81m/s^2".

Corpse Example
You might double check your corpse example. It seems that you have created a constant velocity problem (a=o). The only force that would need to be balanced by the person doing the dragging would be the frictional forces between the corpse and the ground. I didn't see a coefficient of friction for that, so I was wondering how you calculated the force.

+ & - Acceleration Examples
I like the examples of positive and negative acceleration. I think that is a really hard concept.

Role a ball down a ramp and mark the distance from the ramp it travelled. You must have no less than 5.
Example:
Distance
1 Sec.
4 cm
2 Sec.
8 cm
3 Sec.
12 cm
4 Sec.
16 cm
5 Sec.
20 cm
After you find your points Graph them.

Example- If you and your pet jellyfish are pulling your Lamborghini out of the first circle of hell, an Dr Manhattan stops by and freezes time, what is the net force of You and your jelly fish pulling the exotic car. You weigh 150 kilograms and your jellyfish weigh 30 kilograms. The car weighs 1569 kilograms.
Complete Opposite Forces- When two forces pull in the complete opposite directions (180 degrees) the net force is the greatest amount minus the least. If they are the same amount then the net force zero.

Boom shakalaka the anwser is 860 newtons
Net Force
Net Force- The total of force actiing upon the object.
Parallel Forces- If the forces are in the same direction, then simply add then together.

What do you think?
yea they should be embarrassed

What do you think?
and W3 and G2!!!
