Reducing friction with pencils
Place round pencils under a heavy box. Join a string to the box and find the force required to move it across a table. Search the force needed to move the box without the rollers. Summarize the data get and suggest explanations for the results.

Electric field (intensity) is a vector number. Electric field because of a positive particle is always away from the charge and that because of a negative charge is always toward
gravitational potential energy = integral of force with respect to displacement. Find height to drop 59g egg so that it just misses touching ground.
Suppose a fluid (say, water) occupies a domain D ⊂ R 3 and has velocity field V=V(x, t). A substance (say, a day) is suspended into the fluid and will be transported by the fluid
