Strong Nuclear Force (Grades 11-12)
Strong Nuclear Force
Instructions: Read each question carefully. For any questions involving calculations, you must show all your process.
- They learned what held the nucleus together.
- They learned the existence of quarks.
- They learned that there were individual protons and neutrons in the nucleus.
- They learned why the mass of an element was greater than the sum of its protons.
- It is only attractive, never repulsive.
- It acts on both charged and neutral particles.
- It acts on protons, neutrons , and electrons to hold the nucleus together.
- It is a short range force.
- relates energy, mass, and the speed of light.
- shows scientists how mass can be converted into pure energy.
- describes how much mass is associated with a given amount of energy and how much energy it takes to create a given amount of mass.
- showed how all matter had a rest energy.
**Remember, [math]E=mc^2[/math], where c, the speed of light, is equal to [math]3xx10^8m/sec[/math], and [math]m[/math] is the mass in [math]kg[/math].
Given: [math]"Speed of light " c=3xx10^8m/s[/math]
- nuclear energy; fission reaction
- binding energy; nuclear reaction
- binding energy; fission reaction
- nuclear fission; strong force
