QUESTIONS WITH COMPLETE SOLUTIONS

4. gravitation force... - ANSWER ->increase with increasing mass and
decreases with increasing distance.
It's always attractive
4. law of gravity - ANSWER ->- two interacting objects always attract each
other
- each force is proportional to the mass of the object on which it acts
- the two forces in each interaction obey the thired law of motion
- force is weaker if two objects are farther apart
4. law of gravity formula - ANSWER ->f = (GmM) / d squared G=
gravity, is a constant f = gravitation force m / M = mass of 2
objects
d = separation of the two objects
4. electric force... - ANSWER ->increases with increasing charge &
decreases with increasing distance. it can either be attractive or
repulsive
4. electrical model of matter - ANSWER ->moves one of the constants either
off or onto the object = charged.
objects charged by rubbing = materials contain both constituents
4.electrical force law - ANSWER ->- objects w/ same charge repel each other
// opposite charges = attract
, - strength depends on amount of extra charge and proximity - these forces
obey Newton's 3rd law and strength depends on the net charges of the
objects and the distance
- k = constant electrical force
4. electrical currents: conductors - ANSWER ->materials where electroncs
that are free to move on the surface through the interior
4. electrical currents: insulators - ANSWER ->materials that do not permit
this free interior motion of electrons
4. electrical currents: semiconductors - ANSWER ->contain a few free
electrons
4. electrical currents neutral charge - ANSWER ->flows in a circuit
4. electromagnetic charge - ANSWER ->complete interaction due to
electric charge
5. acceleration of an object under the influence of gravity... - ANSWER
>35 km/hr per second
5. Gravitational acceleration - ANSWER ->strength of force = proportional to
object's mass, NOT motion
strength of gravitational force does not depend on if an object is going up or
down
5. contact forces - ANSWER ->1. friction
2. normal force
5. forces with matter: - ANSWER ->ELECTRICAL - hold matter together NET
FORCE - SUM OF ALL THE FORCES ACTING ON IT
