Which one of Newton's laws is this equation from and why?

In summary, Newton's laws of motion are a set of three physical laws that describe how objects move and interact with each other. The first law of motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force. The 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 its mass. The third law of motion, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. To determine which law an equation represents, one can examine the variables and relationships within the

marshall4,
sorry but I think any law in physics has the form "If...then...".
Could you please explain what your symbols mean, i.e. what physical situation this equation describes? Thanks.
 
  • #3
It comes from the action reaction law and the a=F/m law.
 
  • #4
That would be Newtons second law. Force is proportional to and in the same direction as acceleration and inversial propotional to mass.

What are Newton's laws of motion?

Newton's laws of motion are a set of three physical laws that describe how objects move and interact with each other.

What is the first law of motion?

The first law of motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.

What is the second law of motion?

The 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 its mass.

What is the third law of motion?

The third law of motion, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction.

How can I determine which one of Newton's laws an equation is from?

The first law of motion is related to the concept of inertia, the second law involves force and acceleration, and the third law deals with action and reaction. By examining the variables and relationships in an equation, you can determine which law it is representing.
