Physics equations

• 1. Weight ( N ) 


  Mass( kg ) X gravitational field strength ( g )
• 5. Pressure ( Pa ) =


  Force normal to a surface ( N ) ÷ Area of that surface ( m²)
• 2. work done ( J ) = 


  force ( N ) x distance ( along the line of action of the force ) ( m )
• 3)force applied to a spring ( N ) =


  spring constant ( N/m) x extension (m)
• 4) moment of a force (Nm) =


  force ( N ) x distance ( normal to a direction of force) ( m )
• 6) distance traveled (m) =


  speed ( m/s ) x time (s)
• 7) acceleration (m/s² )=


  change in velocity (m/s) ÷ time taken ( s )
• 8) resultant force ( N ) =


  mass ( kg ) x velocity (m/s)
• 9) ( HT ) momentum (kg m/s )


  mass (kg) x acceleration (m/s² )
• 10) kinetic energy (J) = 


  0.5 x mass (kg) x speed² (s)
