Can you think of a way to test if morals are a law of physics?

Well, morals are an emergent property of social behavior. Social behavior is an emergent property of biology. Biology is an emergent property of chemistry. Chemistry is an emergent property of physics. So, in a sense, morals are based in physics, even though the connection admittedly is rather tenuous.

Morality exists in the mind, expressed through one's actions. As such, physics does not apply.

Research shows that the reason humans struggle with emotion to find equitable solutions is pinpointed the region of the brain called the insular cortex, or insula, which is also the seat of emotional reactions.

The fact that the brain has such a robust response to unfairness shows that sensing unfairness is a basic evolved capacity.

The emotional response to unfairness pushes people from extreme inequity and drives them to be fair. This observation shows our basic impulse to be fair isn't a complicated thing that we learn.

It therefore fully illustrates that all humans have morals controlled by the brain and that Christians are entirely wrong to try and claim morals as their own!!!!

But Christians found a way round it!

Government statistics show that Christians are vastly over represented in prisons for sexual, violent and fraudulent crime whilst year on year government figures show atheists make up only 2% of the prison population!

The Catholic Church is paying millions in compensation for the sex/paedophile crimes of their priests alone!

Christians are vastly over represented in the divorce courts!

Christians invented the concept of sin and then the idea that you could sin, ask forgiveness, get pardoned and start with a clean sheet!

So no surprise that they are so expert at it is it‽

A Christian is a man that feels repentance on Sunday for what he did on Saturday and is going to do on Monday. - Thomas Russell Ybarra

It seems you have a misunderstanding of what morality of physics is. Or, maybe you just don't understand the concept of what a law is in terms of science.

Morality is about well being. Perhaps you're conflating these ideas because we live physical universe, and that dictates what the consequences of our actions are. Say someone is cut with a knife. And, there's things like kinetic energy at play. But, that doesn't make the morality of the action a law of physics. Between cutting someone, or not cutting someone, neither outcome violates the known properties of matter and energy.

Furthermore, the same physical result could be viewed as either moral or immoral depending on context. If someone was cut in order to harm them, then that is immoral. But, if a surgeon makes an incision in service of a life saving operation, that cut may be the absolute most moral thing for them to do in that situation.

So, I don't really know what you're trying to get at, but I think there's a serious flaw in your question at a conceptual level.

No. Christian Morality comes from Luke 6:31. Jesus said, "Do to others as you would have them do to you." There is no record of this instruction before Jesus said it.

Morals aren't laws of physics. Laws of physics describe precisely how different components are related to one another. Such as: PV=nRT, E=mc^2, F=ma, and so on.

Morals are part of philosophy. Ethics, or moral philosophy, is an entire branch of philosophy that seeks to resolve questions of human morality by defining concepts such as good and evil, right and wrong, virtue and vice, justice and crime. As a field of intellectual inquiry, moral philosophy also is related to the fields of moral psychology, descriptive ethics, and value theory.

Morals are not a law of physics.

Pushing some of the roof proves gravity, not if pushing people of buildings is a moral thing to do. (It isn't a moral thing to do but morals are opinions.)

Morality has nothing to do with science.

they are not to do with physics....SEE TEN COMMANDS IN EX 20

yes it's called the Bible.
