​How to Calculate Net force on an Object

​If I know the mass of the object, and I know the acceleration of the object, all i have to do is multiply the two numbers to figure out the net force acting on the object!!!

​EX: A 1,000kg car comes to a stop. If the vehicle is accelerating at -1.2 m/s which force is closest to the net force acting on the vehicle? ( - means it is..?)

​Type : 1,000 in first multiply it by -1.2 = -1,200N
