9.3 Forces In Action

Question 1

Atoms

Answer 1

Atom: A very small particle that makes up all things. Atoms have the same properties as the objects they make up

Question 2

Negatively charged

Answer 2

Negative electric charge: The charge on an atom or object with more electrons than protons

Question 3

Positively charged

Answer 3

Positively charged: the charge on an atom or object with fewer electrons than protons

Question 4

Protons

Answer 4

Protons: tiny, but heavy, particle found in the nucleus of an atom. Protons have a positive electrical charge

Question 5

Neutrons

Answer 5

Neutrons: tiny, but heavy, particles found in the nucleus of an atom. Neutrons have no electrical charge

Question 6

Electrons:

Answer 6

Electrons: very light, negatively charged particles inside an atom. Electrons move around the central nucleus of an atom

Question 7

Insulators

Answer 7

Insulators: materials that do not allow electric charge to flow through them

Question 8

Conductors

Answer 8

Conductors: materials that allow electric charge to flow through them
