According to Newton's second law, how are acceleration and mass related? Directly or indirectly when force is constant?
I believe it indirectly. Am I right?

Newton's Second Law: Acceleration & Mass Relationship

In summary, according to Newton's second law, acceleration and mass are indirectly related when force is constant. This means that if one quantity is doubled, the other one will be halved. In the given scenario, if the mass is doubled but the force stays the same, the acceleration will be halved.

Do you understand the difference between "directly" and "indirectly"?

I guess not. Would you mind explaining it? I was under the impression that indirectly means the same as inversely.

You do know the difference. So if the relation is "indirectly" when one quantity is, say, doubled, the other one has to be halved.
Now look at Newton's Second Law. If the mass is doubled but the force has to stay the same what ought to happen to the acceleration? Is it halved or also doubled?

Related to Newton's Second Law: Acceleration & Mass Relationship
1. What is Newton's Second Law?
Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the mass of the object. This means that the greater the force applied to an object, the greater its acceleration will be, and the more massive an object is, the less it will accelerate.
2. What is the formula for Newton's Second Law?
The formula for Newton's Second Law is F = m x a, where F represents the net force applied to an object, m represents the mass of the object, and a represents the acceleration of the object.
3. How does mass affect acceleration according to Newton's Second Law?
According to Newton's Second Law, mass and acceleration have an inverse relationship. This means that as the mass of an object increases, its acceleration will decrease, and vice versa. This is because more massive objects require more force to accelerate at the same rate as less massive objects.
4. How does force affect acceleration according to Newton's Second Law?
According to Newton's Second Law, the greater the force applied to an object, the greater its acceleration will be. This means that a larger force will cause the object to accelerate more quickly, while a smaller force will result in a slower acceleration.
5. Can Newton's Second Law be applied to objects moving at a constant velocity?
No, Newton's Second Law only applies to objects that are accelerating. Objects moving at a constant velocity have no net force acting on them, so there is no acceleration. However, if the velocity of an object changes, then the law can be applied to calculate the force required for that change in velocity.
