Calculating the resultant force on a body by a combination of forces is a matter of adding the different acting forces componentwise, as discussed in Halliday and Resnick's "Fundamentals of Physics." Equivalently, you perform vector addition. Graphically, this means maintaining the angle of the v...
Calculate the distance from the Earth when the resultant gravitational field acting on it is zero. Consider only the gravitational force of the Earth and the Moon.Given that the mass of the Moon is 7.4 x 1022 kg and distance between centres of the Earth and the Moon is 3.8 x 108 m....
Calculate the electric force between two {eq}\displaystyle \rm 1 \ kg {/eq} balls each with {eq}\displaystyle \rm 1 \ C {/eq} and separated by {eq}\displaystyle \rm 1 \ m {/eq}. Electric Force: Two body or particle experiences force from each other when...
Two forces are exerted on an object. A 32 N force acts at 220 degrees and a 53 N force acts at 315 degrees. What are the magnitude and direction of the equilibrant? Mathematically determine the resultant force if two forces A and B act on an object. Force A is...
Any force that exists is a vector, which means that it has a magnitude and a direction associated with it. The net force on an object can be treated like the hypotenuse of a right triangle. The two sides of the triangle a...
Add this velocity to the initial velocity. In the example above, if the object had an initial velocity of 5 meters per second, the resultant velocity would be 34.4 meters per second. The overall formula here is v (final) – at + v (initial) where "v" is velocity, "a" is acceleratio...

To calculate the magnitude of force vectors, you use the components along with Pythagoras' theorem. Think of the x coordinate of the force as the base of a triangle, the y component as the height of the triangle, and the hypotenuse as the resultant force from both components...
So, how can we find out if forces are balanced on an object? One tool that scientists use is called a free-body diagram. Free body diagrams are drawings that help scientists sort out what forces are acting on an object. For simplicity, the object is always drawn as a dot. Then, force...
