- To Calculate Weight:
Weight = Mass x Gravitational Field Strength
( Newton's) (Kilograms) (Newton's/Kilograms)
- To Calculate Resultant Force:
Resultant Force = Mass x Acceleration
(Newton's) (Kilograms) (Meters/Second²)
- To Calculate Stopping Distance:
Stopping Distance = Thinking Distance + Braking Distance
- To Calculate Work Done:
Work Done = Force Applied x Distance Moved in Direction of Force
(Joules) (Newton's) (Meters)
- To Calculate Kinetic Energy:
Kinetic Energy = ½ x Mass x Velocity²
