atomic mass

in the atomic nucleus

outside the nucleus, yet very near it because they are attracted to the protons

outside the nucleus and often far from it - most of an atom's volume is its electron cloud

either in the nucleus or around it - electrons are readily found anywhere in an atom

v = u + a t

s = v t - ½ a t2

v = u t + ½ g t2

K = ½ m v2

v2 = u2 + 2 a s

P = F /A

P =F A

P = Force * Volume

P = Force / Volume

? r

m ?

¾ ? r

m ?2

T = m ?2

T = F r

T = ½ m ?2

None of the above

E= m c2

E= h ?

E= ½ m v2+m g h

All of the above

K = m g h

K = ½ m v2

K = ½ m v2 + m g h

K = ½ m v2 * m g h
