Question

Which statement about the acceleration of an object is correct?

a. The acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object.

b. The acceleration of an object is directly proportional to the net external force acting on the object and directly proportional to the mass of the object.

c. The acceleration of an object is inversely proportional to the net external force acting on the object and inversely proportional to the mass of the object.

d. The acceleration of an object is inversely proportional to the net external force acting on the object and directly proportional to the mass of the object.

Answer 1

a. The acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object.

Step-by-step explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Acceleration = force/mass

Hence, the statement about the acceleration of an object which is correct is that the acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object.
