Physical Science Module 12
Physics is just as important a realm of science as any other, as it deals with the rather significant topics of motion, matter, force, energy and behaviour through space and time. What can you tell us about it?

True
- B.
False
- 2.Charging an object by allowing it to come into contact with an object that already has an electrical charge is called:
- A.
Charging by Conduction
- B.
Charging by Induction
- 3.Charging an object without direct contact between the object and a charge is called:
- A.
Charging by Conduction
- B.
Charging by Induction
- 4.The amount of charge that travels past a fixed point in an electric circuit each second is called:
- A.
Electrical Current
- B.
Conventional Current
- 5.Current that flows from the positive side of the battery to the negative side is called: (This is the way current is drawn in circuit diagrams, even though it is wrong.)
- A.
Electrical Current
- B.
Conventional Current
- 6.The ability of a material to impede the flow of charge is called:
- A.
Impedance
- B.
Tolerance
- C.
Resistance
- D.
Restasis
- 7.A(n) _________________ is a circuit that does not have a complete connection between the two sides of the power source. As a result, current does not flow.
- A.
Open Circuit
- B.
Closed Circuit
- 8.If you have one object with a negative charge and one object with a positive charge, will the force exerted by these two objects be toward each other or away from each other?
- A.
Toward Each Other
- B.
Away From Each Other
- 9.The force between the south pole of one magnet and the south pole of another magnet is measured. If the distance between those magnets is suddenly doubled, how will the new force compare with the old one?
- A.
The force will decrease by a factor of 2
- B.
The force will increase by a factor of 2
- C.
The force will decrease by a factor of 4
- D.
The force will increase by a factor of 4
- 10.From the previous question: Is the force attractive or repulsive? Previous question : The force between the south pole of one magnet and the south pole of another magnet is measured. If the distance between those magnets is suddenly doubled, how will the new force compare with the old one?
- A.
This is an attractive force
- B.
This is a repulsive force
- 11.A physicist charges an object with a positively charged rod. If the object develops a negative charge, how did the physicist charge the object?
- A.
The object was charged by conduction
- B.
The object was charged by induction
- 12.If a circuit has a low voltage, you can still get a lot of energy out of the circuit if you put a lot of current through it.
- A.
True
- B.
False
- 13.You are blindfolded and handed two extension cords of equal length. Both have the same current running through them. If the cord in your left hand is warmer than the one in your right hand, which cord is thicker?
- A.
The cord in your right hand is thicker
- B.
The cord in your left hand is thicker
- 14.Conventional current flow in a circuit runs from the _____________end of the battery to the ______________ end.
- A.
Positive to Negative
- B.
Negative to Positive

- A.
Positive to Negative
- B.
Negative to Positive
- 16.In most chandeliers today, when one light bulb goes out, the rest stay lit. Are the light bulbs wired in series or in parallel?
- A.
The light bulbs are wired in Series
- B.
The light bulbs are wired in Parallel
- 17.The atoms in an object are not aligned. Is the object a magnet?
- A.
The object is a magnet
- B.
The object is not a magnet
- 18.You cut a magnet in half - right between the north and south poles. How many north poles and south poles do you now have?
- A.
One North pole and 2 South poles
- B.
Two North poles and 2 South poles
- C.
Four North poles and 4 South poles
