Forces General
This combination of forces causes acceleration.
What are unbalanced forces?
The description of gravitational force.
What is the attractive force between objects with mass?
A build up of these leads to electrostatic force.
What are charges?
Magnetic force describes how these objects attract or repel materials.
What are magnets?
This describes forces that can act without objects touching.
What are non-contact forces?
These are the two factors in the strength of gravitation force.
What are the masses of the objects and distance between them?
This is how neutral objects become charged.
What is the transfer of electrons?
These "ends" of the magnet either attract or repel other magnetic objects.
What are poles?
This indicates an object is experiencing "balanced forces."
What is constant velocity?
The force that objects experience in Earth's atmosphere as they fall down due to gravity.
What is air resistance?
Three ways that an object could become electrically charged.
What are conduction, polarization, and friction?
These metals are commonly called "ferromagnetic" -- meaning they naturally have a magnetic field.
Cobalt, iron, and nickel.
The force that is transmitted through rope, cable, or wire.
What is tension force?
The acceleration rate at which objects fall to the ground on Earth.
What is 9.8 m/s2?
In magnetic and electric fields, this is the behavior of both charges and poles.
What is "opposites attract" and "like repels"?
The electrons in magnetic objects have this special pattern of movement.
What is spinning in the same direction?
The force that is generated between two surfaces that opposes the motion of objects.
What is friction force?
This scientist's model of gravity assumes that the mass of objects is distorting space-time, explaining planets in orbit.
Who is Albert Einstein?
In an electric field, as the distance increases, this decreases.
What is strength?
A device that creates magnetic fields through moving electric currents.
What is an electromanget?
