What is the equation that links acceleration (a), mass (m), and resultant force (F)?

• Resultant Force = Mass x Acceleration, or F=ma

• Resultant Force = Mass / Acceleration, or F=m/a

• Resultant Force = Acceleration / Mass, or F=a/m

What is the equation that links gravitational field strength (g), mass (m) and weight (W)?

• Weight = Mass x Gravitational Field Strength, or W=mg

• Weight = Mass / Gravitational Field Strength, or W=m/g

• Weight = Gravitational Field Strength / Mass, or W=g/m

What is the equation that links distance (s), force (F) and work done (W)?

• Work Done = Force x Distance, or W=Fs

• Work Done = Force / Distance, or W=F/s

• Work Done = Distance / Force, or W=s/F
