Question | Answer |
---|---|
power | p=Wd/t power=work done/time |
potential difference | V=IxR volts= amperes(A)x Ohms |
charge | Q= IxT Coulombs= Amperes x time |
Energy | E= QxV or V=E/Q Energy (joules)= Coulombs x Volts |
Force | F= ma force= mass x acceleration |
weight | W=m x g |
speed | s= d/t speed= distance/time |
speed | c= f x λ speed= frequency x metres |
potential energy | PE= m x g x h potential energy = mass x grams (10) x height |
Acceleration | a= f/m acceleration = force/mass |
work done | Wd=f x d workdone= force x distance |
Kinetic Energy | KE=½ x m x v2 kinetic Energy= ½ x mass x velocity |
