Science (Physics)

• 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

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
