forces and motions
the region around a magnet where the magnet force is located
magnetic feild
applied when two objects touch
contact force; example friction
an object can apply without touching another object
non-contact force
when equal forces act apon and object in opposite directions
balancee forces
equals zero
balanced force
when forces acting apon an object are not equal
unbalanced forces
change in motion
acceleration
always in the direction of the greater force
unbalenced forces
net force dosen't equal zero
unbalanced forces
the combination of all the forces acting apon an object
net force
attractive force that exits between all objects that have mass
gravity
the distance between the objects
1 of the 2 things that the strength of the force depends on
the mass of the objects
2 of the 2 things that the strength of the force depends on
a force that opposes the motion of an object
friction
when two or more objects come in contact
friction
