|
F=ma
|
|
|
a=F/m
|
|
|
acceleration of an object=net force on object/mass of object
|
|
|
None of the above
|
Detailed explanation-1: -According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m .
Detailed explanation-2: -Newton’s Second Law: Force His second law defines a force to be equal to change in momentum (mass times velocity) per change in time. Momentum is defined to be the mass m of an object times its velocity V.
Detailed explanation-3: -Newton’s second law states that the net external force acting on an object is responsible for the acceleration of the object. If air resistance is negligible, the net external force on a falling object is only the gravitational force (i.e., the weight of the object).
Detailed explanation-4: -Newton’s second law says that the acceleration and net external force are directly proportional, and there is an inversely proportional relationship between acceleration and mass.
