You can properly use Newton’s third law to help predict the displacement of the object or if the object has enough tension to maintain a hanging position. If you want to learn more about the 3 laws of Newton and Newton’s 3rd law, you may use any of Newton’s 3rd law examples and samples on the links above.
There are two formulas people can use to calculate Newton’s third law. T = W = mg for a free hanging mass and Fnet = T – W for movement. Determine which type of formula you will use for the specific problem.
After you have determined the formula you will use, you must write down all the variables the problem has laid out for you. Be sure that each variable in the problem has the correct measurements, if they do not have the appropriate measurements be sure to convert them as necessary.
Substitute the given variables to the formula of net force or tension. This will give you the missing value you will need to find in the formula. Be sure to move the unidentified value to the left side of the equation by doing the appropriate steps.
Solve for the missing value and be sure it will have the correct measurement associated with the missing value. If it doesn’t have the correct measurement, convert it accordingly.
Newton’s third law of motion allows people to know how much external force is required to disturb the equilibrium or balance of an object to move it in a specific direction. This is important as many of our basic actions and tools require movement.
