As Fast As You Can

  • Speed- distance covering in a certain time
  • Velocity- distance covering in a certain time and direction
  • Aceleration
  • Forces- F=MA
  • Stopping distances

Speed= distance (M)

              time (s)

Velocity= displacment (M)

                Time (s)

Acceleration= a velocity = V-U

                       time             6

Roller Coaster and Relativity

KE=PE 

  • Work
  • KE= einetic energy
  • PE= potential energy
  •  P= I x V    - electrical energy
  • conservation of energy
  • P=worker(N)   -Power
  • Time(s)          -Relativity

Work= force x distance
