Physics unit 8

Which force helps atoms become more stable? It is the force that is responsible for decays, and radioactivity?

Weak Nuclear Force

Which force is the ‘glue’ that holds the nucleus together? Without this force visible matter would not exist?

Strong Nuclear force

Which force is a mutual force of attraction between pairs of masses? This force can explain the nature of our solar system, and why the planets orbit the sun.

Gravity Force

Which force is a mutual force of attraction or repulsion between charged particles? This force holds the electrons in ‘orbit’ around the nucleus of the atom.

Electromagnetic Force

______________________ is defined as a push or a pull. This quantity has standard units of __________________. 

Force ; Newtons

____________________________ forces act at a distance. 

Field

__________________________ forces are a result of contact between objects

Contact

An object’s tendency to resist the change in its state of motion is called __________. 

Inertia

An object at rest has an acceleration of _____________. An object at rest stays at rest until an _______________ ______________ acts. When this  _______________ ______________acts, the object will accelerate. 

Zero; unbalanced Force, unbalanced Force

An object in motion at a constant velocity has an acceleration of ________________. An object moving at a constant velocity will tend to stay moving at a constant velocity until an  _______________ ______________ acts.  When this  _______________ ______________acts, the object will accelerate. 

Zero; unbalanced Force, unbalanced Force

An action-reaction is between two objects. For every action _________ applied onto object 1 from object 2, an ________ and __________ force applies onto object 2 from object 1. In other words, if Object 1 pushes Object 2 with a force of 500 N to East, object 2 will push back with a force of _________________ to the ______________. 

Force ; Equal , opposite, 500n , west

Name the four fundamental forces that govern the universe .

Gravity , electromagnetic , strong nuclear forces, weak nuclear forces.

List the four fundamental forces in order from weakest to strongest.

Gravity , Weak nuclear force , electromagnetic , Strong nuclear force.

Which Force is your least favorite of the four fundamental forces and why?

The strong nuclear force is my least favorite because I think It the most confusing.

Which Force is your favorite of the four fundamental forces and why?

My favorite is gravity because I think it's the most interesting and how it keeps the planets in their orbit.
