Physics

• Force- Push or Pull
• Four types of forces

  1. Gravitational Force
  2. Electromagnetic Force
  3. Strong Nuclear Force
  4. Weak Nuclear Force
• Newtons 1st-3rd laws

  1. Inertia
  2. Mass Force Acceleration
  3. Action and Reaction
• Gravitational Force- It is the force of attraction between objects by virtue of their masses
• Electromagnetic Force- It is either an attractive force or repulsive force between charged bodies
• Strong nuclear force- It holds the constituents of the nucleus of an atom together
• Weak nuclear force- Plays a role in the radioactive decay of some nuclei
• The grand unified theory- aims to unify the three fundamental forces namely electromagnetic force, strong and weak nuclear force.
• The theory of everything- it aims to unify all fundamental forces
