4 Fundamental Forces

Multiple Choice

Which are the four fundamental forces

• Push , Pull, Rotate, Fly

• Gravity, Strong, Weak , Electromagnetic

• Pull. Push, Rotate, Levitate

• Gravity ,Strong, Weird, Electric

Gravity

The weakest attractive force between any two objects, which depends on the masses of the objects and the distance between them
o Law of universal gravitation
• Force = G𝑚1𝑚2 𝑑2

Multiple Choice

What kind of force does gravity have

• weird

• super

• strong

• weak

Strong Nuclear Force

o The force that holds together the atomic nucleus
Protons, Electrons and Neutrons

Fill in the Blanks

Weak Nuclear Force

 The weak attraction in the nucleus between protons and neutrons; can cause neutrons to decay in the instance of a high proton to neutron ratio
o Fission • A parent atom that splits into two daughter atoms • Ex: beta decay o A beta particle is emitted from an atomic nucleus. o 𝛽 𝑑𝑒𝑐𝑎𝑦 = 6 14𝐶 → 7 14𝑁 + −1 0 𝑒 (𝑏𝑒𝑡𝑎 𝑝𝑎𝑟𝑡𝑖𝑐𝑙𝑒) o Fusion • Two or more atomic nuclei combine to form a new nuclei.
