Formulae And Relationships Flashcards
Relationship between
Time, speed and distance
Average speed = distance/time
Relationship between
Force mass and acceleration
Force = mass x acceleration
Relationship between
Acceleration, velocity and time
Acceleration = change in velocity/time taken
Relationship between
Mass, weight and gravitational field
Weight = mass x gravitational field strength
Relationship between
Charge, current and time
Charge = current x time
Relationship between
Resistance, voltage and current
Voltage = current x resistance
Relationship between
Voltage, current and electrical power
Electrical power = voltage x current
