To calculate the net force, or unbalanced force, of a Newtonian object, find the sum of all forces presently acting upon it. These include gravity, friction and other forces depending on the scenario. You need only a few figures and computations to calculate an object's net force, which is required for acceleration and is expressed in Newtons.Know More
To help keep track of the forces involved, create a free-body diagram, which is a simple sketch of the object and the forces acting upon it. Draw a rough diagram of the object, and then use arrows to indicate the direction of each force.
Identify the forces acting on your object. Note that some forces cancel each other out and have no bearing on your total Newtonian net force. Forces are identified according to the condition, environment and behavior of an object.
Find the sum of these relevant forces by applying their force, in Newtons, to your diagram. Forces moving toward the right in the free-body diagram are considered positive forces, and those moving toward the left are negative. Add the forces together. The result is the Newtonian net force.
A Venturi pump uses the kinetic energy in a fast-moving fluid to move another liquid or semi-liquid substance. These pumps are abundant in sewage treatment plants because they reliably move large volumes of thick, heterogeneous material without clogging or locking. Venturi pumps are also useful in quarries, refineries and other industries that generate thick liquid waste.Full Answer >
Solids maintain a definite shape and volume because their atoms are tightly bound to each other. Solids can be crystalline or amorphous. In crystalline solids, such as ice and metal, atoms are arranged in a regular geometric lattice. In amorphous solids, such as wax and many plastics, the arrangement is irregular.Full Answer >
Force and motion are related because exerting force on an object causes a change in motion. An example would be kicking a ball to propel it forward. Two examples of natural forces are gravity and magnetism.Full Answer >
Isaac Newton's theory of gravity states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The law is represented as: F=G (m1m2)/R.Full Answer >
