### Motion - Comprehensive

1. The scientist best known for his contributions to motion was Galileo:
True
False

2.Aristotle thought motion on Earth was:
Circular
Octogonal
Linear
Curved

3. Galileo helped us to believe that when objects move they always:
Want to move in a straight line
Want to move curved
Want to stop
Want to move in a straight line at the same speed

4. Objects in 'real life' do not travel in straight line at constant speeds because of:
The planetary gravitation
Friction
The lack of karmic alliance with the souls who deem it so
They just don't want to

5. When objects fall from heights, acceleration at which they travel is:
Always the same everwhere in the universe
Independent of mass and different everywhere in the universe
Dependent on mass and different everywhere in the galaxy
None of the above

6. The acceleration of an object is dependent on:
The object's mass
The force applies on the mass
The position of the mass
None of the above

7. An object in motion will stay in motion at constant speed in a straight line unless acted upon by an external unbalanced force is reffered to as:
Inertia
Newton's third law
Magic
Newton's fourth law

8.By Newton's 3rd law, we are told that every action has an equal and opposite reaction. Why is it then that when a person fires a bullet with a gun, the forces don't cancel out? :
Because the force supplied is from the explosion
Because life is a box of chocolates
Because the forces applied are on the opposite objects
Because the forces applied are on the opposite axis

9. A force is defined as a:
A fall
A push or pull
A push
A pull

10. All objects experiance inertia when moving, anywhere in the universe:
True
False

11. Aristotle said that the universe was:
Geocentric
Heliocentric
Earthcentrical
Terracentric

12. Aristotle said motion on Earth/Universe was:
Linear/Circular
Linear/Linear
Circular/Circular
Linear/Circular

13. Copernicus was best known for his:
Chicken surprise recipe
Statement that the sun was at the center of the universe
Statement that the Earth was at the center of the universe
None of the above

14. Copernicus was not allowed to tell anyone about his reasearch because:
He would be assinated by the local maffia
He did not do his own work, and would hence be a science pirate
He only discovered his work at the end of his life
He could be condemned by the church to death

15. Galileo was known for his discoveries because he said:
I am god
That the Earth was at the centre of the universe
That the sun was at the centre of the universe
The sky is falling

16. Kepler discovered that the planets had elliptical orbits:
True
False

Inertia
Gravition
Both inertia and gravition
None of the above

18. Unlike most scientists of his time Newton:
Believed that god was the creator of the universe
Believed that god was non-existant
All his laws were 100% correct to this day
None of the above

19. The tides on the Earth are caused by:
Lava Flow
Wind
People swimming
The moon

20. In reality the orbits of planets are not 100% elliptical. This is because orbits are:
Not alligned
Circular
Have perturbations
Have gammarations

21. Sound is a ___________ type of wave:
Transverse
Longitudinal
Normal
Not a wave

22.To hear a sound you need a:
Small
Medium
Large
Stereo

23. Echo is:
A reflection of sound
A ghost talking
A double vibration of air
None of the above

24. The speed of sound in air is:
Greater than that of light
100km/hr
100m/hr
331 m/s

25. The Doppler effect is caused by::
Waves getting less intense with distance
The properties of air
The ressonance of air
None of the above

26. You see a lightning bolt before you hear it because:
Sound is faster than light
The forces are uneven
Light is faster than sound
None of the above

27. Stereos operate by vibrating the air, and subsequently your ears:
True
False

28.The 'volume' of a sound wave can be adjusted by increasing the:
Frequency
Amplitude
Wavelength
Period

29. Sonar is an application of:
Difraction
Echo
The speed of light
The speed of sound and echo

30. You can see a baby in its mother's womb with ultrasonic sounds:
True
False

31. A capacitor is like:
A switch
A retarding force
A water tank that can empty
A power source

32. A transistor is like:
A switch
A retarding forc
A water tank that can empty
A power source

33.All natural magnets have:
A north pole
A south pole
A north and south pole
An east and west pole

34. The symbol for voltage is:
Vol
eV
A
V

35. An electron carries a _____________ charge:
Positive
Negative
Neutral
None of the above

36. A proton orbits around the centre if the atom:
True
False

37. An protron carries a _____________ charge:
Positive
Negative
Neutral
None of the above

38. An neutron carries a _____________ charge:
Positive
Negative
Neutral
None of the above

39. The symbol for current is:
C
A
V
R

40. When electricty passes through a conductor, the conductor exhibits a:
Heat field
Gravitational impedance
A hot and cold zone
A magnetic field

41. Light is a longitudinal wave:
True
False

42.Light can be transformed into energy:
