Lecture 1: Review – Derivation of formula/Mathematics of Science

 

     1.Equations/Relationships/Graphs

     2.Deriving

          a.Direct Relationship

          b.Indirect Relationship

 

 

 

 

 

 

 

 

LECTURE 2 :Review and Physical Quantities

  1. Scalar - Magnitude

  2. Vector

  • Magnitude/direction

             a.Distance

             b.Displacement

             c.Speed

             d.Velocity

             e.Accelaration

     Acceleration will happen if:

  1. Velocity increases

  2. Velocity decreases

  3. Change in direction

     

     

     

     

     

     

     

     

     

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

LECTURE 3 : UAM EQUATIONS

  1. Horizontal displacement

  2. Vertical displacement

     

     

     

     

     

     

     

     

     

Lecture 4: UAM  in Vertical Free Fall

Lecture 5 - 6: Projectile Motion

 Projectile

  1. Initial Velocity

  2. Gravitational Force

Vertical

  • Motion of a freely falling object

  • Force due to gravity

  • Vertical components of velocity changes with time

Horizontal

            -motion of a ball rolling freely along a level surface

        - horizontal velocity in always constant

Parabolic

  • Path traced by an object  accelerating only in the vertical direction while moving at constant horizontal velocity

Trajectory

  • Curved path travelled by the projectile

     

     

     

     

     

     

     

     

     

Lecture 7: Deriving the Formula for Projectile Motion

Lecture 8: Applying Equations for Projectile Motion

Lecture 9: Impulse & Momentum

P =  m . v

Momentum          

   -inertia in motion

Mass  = kg

Velocity = m/s

P= kg m/s

Lecture 10: Conservation in Momentum

3rd  Law of Motion Interaction

  • In every action there is an equal but opposite reaction

     

     

     

     

     

     

     

     

     

Lecture 11: Collision

Collision

  • Encounter between 2 objects resulting in exchange of impulse & momentum

  • 2 objects exert force to one another

Types of Collision

  1. Elastic = KE is conserverd

  2. Inelastic = KE is not conserved

     

     

     

     

     

     

     

     

     

Lecture 12:  Energy

Energy

  • Is the ability to do work

Work

  • As force is applied on object & object moves in the direction of applied force

Kinetic Energy

  • Possessed by an object in motion

5 Types of KE

  • Radiant energy

  • Thermal energy

  • Sound Energy

  • Electrical Energy

  • Mechanical Energy

Sound Energy

  • Associated with vibration of matter

Mechanical Energy

  • Force acts upon an object  that cause it to move or displaced

Potential energy

  • Stored energy

Gravitational Potential Energy

  • Mass x gravity x height

Clastic potential energy

Chemical Potential Energy

Law of Conservation

  • Energy is neither created nor destroyed. It is only converted from one form to another

Radiant Energy

  • Is the energy of electromagnetic waves. The term is modt commonly used in the fields of radiometry

Electricity

  • Is energy that is caused by moving electric charges

Electrical energy

  • An electric charge that lets work be accomplished

Nuclear Energy

  • Is the energy in the nucleus of an atom

Atoms

  • are the smallest particlesthat can break a material

Two types of particles:

*neutrons

*protons

Nuclear Fission

  • atom are split into smaller atoms. Releasing energy

 

Nuclear Fussion

  • we need light nuclei basically,deuterium and tritum which are two isotopes.

 

Nuclear Energy of the element

  • thermal energy (heat released) kinetic energy of turbine –production of electromagnetic energy.

 

Energy Transformation

  • is the ability to do work

  • it is the process of a energy to another transformation

  • a complete or major change is somethings appearance form  etc.
