Physics

• Kinetic energy is the energy possessed by a body when its in motion ….

  Potential energy occurs in objects due to its position or height from the ground …..
• Light is the best reason why we are able to see things

  The sun is the ultimate source of light and energy on earth

  light travels in straight lines

  many rays traveling together form a beam of light

  when it passes through transparent materials it bends or turns
• Energy can neither be created nor destroyed .. you can only convert it from one form to the other

  • turn off lights when not in need

  • turn off water tap when not in use
• Reflection

  Bouncing back off light after hitting a surface
• Refraction

  Bending of light rays due to change of medium
• Light gets refracted due to change in speed
• Gravity keeps us grounded
• Simple machine makes our work much easier , faster and more efficient

  Reduces one’s effort
