Physics Flashcards
Moment (Nm) =
Force (N) x Distance (m)
Speed (m/s) =
Distance (m) / Time (seconds)
Velocity (m/s) =
Displacement (m) / Time (seconds)
Accelaration (m/s*2) =
[Final Speed (m/s) - Initial Speed (m/s)] / Time (seconds)
Final Speed2 (m/s) - Initial Speed2 (m/s) =
2 x accelaration (m/s*2) x Distance (m)
Resultant Force (N) =
Mass (kg) x Accelaration (m/s*2)
Momentum (kg m/s) =
Mass (kg) x Velocity (m/s)
Force (N) =
Springs
Spring Constant (N/m) x Extension (m)
Pressure (Nm*2) =
Height (m) x Density (kg/m*2) x Gravity (N/kg)
Work (J) =
Force (N) x Distance (m)
Power (W) =
Energy (work, so J) / Time (seconds)
Kinetic Energy (J) =
[Mass (kg) x Speed*2 (m/s)] / 2
Gravitational Potential Energy (J) =
Mass (kg) x Gravity (N/kg) x Height (m)
Elastic Potential Energy (J) =
[Spring Constant (N/m) x Change in Length*2 (m)] / 2
Weight (N) =
Mass (kg) x Gravity (N/kg or m/s*2)
