physical science finals

• Aristotelian


  his attempt was based on inductive-deductive reasoning
• Galilean


  motion can either natural or violent motion
• 3. Galilean 


  he believed that an object thrown at a certain angle is given an impetus
• 4. Aristotelian 


  earth objects/ materials falls towards the center of the earth as it seeks its natural place
• 5. Aristotelean 


  Heavy objects fall faster than the light one with relation to its weight and a proportional speed.
• 6. Aristotelean 


  Objects falls faster in air than water with relation to the resisting force proportional to its speed and medium (air or water
• 7. Aristotelean

  Objects can be moved away from their natural places called Violent Motion, that causes motive force
• 8. Aristotelean 


  There is NO MOTION without FORCE. The speed (v) of an object is proportional to the motive force (F) and inversely proportional to the resistance  (R) of the medium
• 9. Galilean

  Believed that the motion of objects is not simply due to the composition of objects
• 10. Aristotelean

  A projectile is a combination of uniform motion in the horizontal direction and uniformly accelerated motion
• diff. VECTOR


  has both magnitude & direction
• diff, scalar


  magnitude
• ex. Vector


  displacement, velocity, acceleration, momentum, force, weight
• impulse


  is the change in momentum
• ex, Scalar


  length, area, volume, speed, mass, pressure, temperature, energy
• inertia


  an object stays still unless acted upon
• free fall


  other term for gravity
• trajectory


  the path of a projectile
• horizontal motion 


  movement of a projectile motion due to acceleration
• parabolic


  the horizontal distance from the point of release
• 9.8m/s 2squared


  normal gravitational acceleration point
• speed 


  the rate at which an object covers a certain distance
• distance 


  refers to the total length of path traveled by an object
• .


  bending of light around a corner
• .


  changing of speed of light passing through one medium to another
• reflection (c)


  bouncing of light
• dispersion of light

  separation of white light into component colors when it passes through a prism
• wave 


  a travelling disturbance that transport energy to one location into another
• medium


  a material where energy travels through
• propagation


  the movement of the energy
• 2 classifications of waves 


  9.by the presence of a medium.

  10.by the orientation of particle motion relative to the direction of the wave propagation
• 11.mechanical wave 


  a disturbance in matter that carries energy from one place to another
• 12.electromagnetic wave


  propagation of electric and magnetic fields through space
• 13.transverse


  .
• 14. longitudinal 


  .
• explain the EM wave spectrum


  ;
• 2. when is Period (T) of a mechanical wave happen


  .
• 3. Speed (v)


  .
• 4. Periodic 


  .
• 5. Electromagnetic wave with "shorter wavelength(gamma rays, x-rays& UV rays)
