By machining the grooves in the end surfaces of the vertical columns, the contact area is reduced, and therefore the objective of adjusting attracting force is achieved.
However, their velocities are too large for them to remain gravitationally bound by their mutual attractions, implying the presence of either an additional invisible mass component, or an additional attractive force besides gravity.
“The second reason for the success of the JWs is in the attractive force of the jehovist message, in being able to cater to the needs, demands, and expectations of the people of our times.
In the late 17th century, a number of physical astronomy theories drawing from Kepler's work—notably those of Giovanni Alfonso Borelli and Robert Hooke—began to incorporate attractive forces (though not the quasi-spiritual motive species postulated by Kepler) and the Cartesian concept of inertia.
A magnetic switch includes a carrier (1) and a switch (2) provided in the carrier, the switch (2) including two units (21,22) provided separately in the different parts of the carrier, the two units attracted each other to contact by the attracting force occurred by their self magnetic material so as to make the circuit conduct.
Globally aware leaders seek to build institutions that can embody these attitudes and inspire citizens to participate in the emerging aspects of globalization, while at the same time attracting global forces to participate in national development
