Newton 2. The Big EquationYour Turn to PracticeNewton&#39s Second Law as A Guide to ThinkingThe Direction of The Net Force and AccelerationNewton&#39s second law of motion can be formally stated as follows This verbal statement can be expressed in equation form as follows The above equation is often rearranged to a more familiar form as shown below The net force is equated to the product of the mass times the acceleration In this entire discussion the emphasis has been on the net force The acceleration is directly proportional to the net force the net force equals mass times acceleration the acceleration in the same direction as the net force an acceleration is produced by a net force The NET FORCE It is important to remember this distinction Do not use the value of merely “any &#39ole force” in the above equation It is the net force that is related to acceleration As discussed in an earlier lesson the net force is the vector sum of all the forces If all the individual forces acting upon an object are known then the net force can be determined If necessary review this principle by returning to the practice The Fnet= m • a equation is often used in algebraic problem solving The table below can be filled by substituting into the equation and solving for the unknown quantity Try it yourself and then use the click on the buttons to view the answers The numerical information in the table above demonstrates some important qualitative relationships between force mass and acceleration Comparing the values in rows 1 and 2 it can be seen that a doubling of the net force results in a doubling of the acceleration (if mass is held constant) Similarly comparing the values in rows 2 and 4 demonstrates that a halving of the net force results in a halvingof the acceleration (if mass is held constant) Acceleration is directly proportional to net force Furthermore the qualitative relationship between mass and acceleration can be seen by a comparison of the numerical values in the above table Observe from rows 2 and 3 that a doubling of the mass results in a halving of the acceleration (if force is held constant) And similarly rows 4 and 5 show that a halvingof the mass results in a doubling of the acceleration (if force is held constant) Acceleration is inversely proportional to mass The analysis of the table data illustrates t As stated above the direction of the net force is in the same direction as the acceleration Thus if the direction of the acceleration is known then the direction of the net force is also known Consider the two oil drop diagrams below for an acceleration of a car From the diagram determine the direction of the net force that is acting upon the car Then click the buttons to view the answers (If necessary review acceleration from the previous unit).

Newton 2 is a program for solving mechanical equations for movements numerically The equations can be parameterized for interactive investigations of the movements and the according solutions are displayed immediately in a diagram The differential equations (DEQs) are programmed to calculate the time dependence of the velocitiy v(t) of a 3/5 (5)Operating System WindowsCategory Science Tools.

The newton (symbol N) is the International System of Units (SI) derived unit of force It is named after Isaac Newton in recognition of his work on classical mechanics specifically Newton&#39s second law of motion A newton is defined as 1 kg⋅m/s 2 which is the force which gives a mass of 1 kilogram an acceleration of 1 metre per second per Symbol NUnit of SI base units 1 ⋅⋅−2Unit system.

N/m2 – Newton per Square Metre Pressure Unit

N/m2 – Newton per Square Metre Pressure Unit Newtons/Square Meter is a unit that shows how the pascal unit is derived from other SI units Pressure is defined as Force/Area and the SI unit for Force is newtons (N) and the SI unit for Area is Sq Meters (m²) 1 newton per square metre equals 1 pascal The N/m² pressure unit is one of the few.
