(16 cards)
What are the equations for work done?
Work done = force x distance
Work done = power x time
What is the equation for kinetic energy ?
Kinetic energy = 0.5 x mass x (speed)²
What is the equation for gravitational potential energy ?
Gravitational potential energy = mass x gravity x height
What is the equation for efficiency?
Efficiency= useful output/total output
What is the equation for charge?
Charge = current x time
What is the equation for potential difference?
Potential difference = current x resistance
What are the equations for energy transferred?
Energy transferred = charge flow x potential difference
Energy transferred = power x time
What is the equation for mass ?
Mass = density x volume
What are the equations for power?
Power =current x potential difference
Power = (current)² x resistance
What is the equation for a moment?
Moment = force x distance
What is the equation for distance?
Distance = speed x time
What is the equation for the change in velocity ?
Change in velocity = acceleration x time taken
What is the equation for weight?
Weight = mass x gravity
What are the equations for force?
Force = spring constant x extension Force = mass x acceleration Force = pressure x area
What is the equation for momentum ?
Momentum = mass x velocity
What is the equation for wave speed ?
Wave speed = frequency x wavelength
