Why there is a difference in the amount of Newtons measured when you weighed the objects versus when you pulled the objects across a surface? Teacher note: Your answer should mention how the force=mass*acceleration formula is involved.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

568.98

its math

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
