All magnets have a north and a south pole. Which of the following options represents magnets that are attracted to each other
Which electromagnet would have the strongest magnetic force?
Which of the following is NOT a contact force

Newton's first law of motion states
unbalanced forces acting on an object will not change its state of motion
balanced forces acting on an object will not change its state of motion

Levers can be used to
multiply forces
increase mass
decrease mass
stop a force from moving
The greater the mass of on object
the weaker the force of gravity is on it
the greater the force of gravity is on it
mass does not affect gravity

(NW)
(NE)
(F)
(N)
