Ks3 physics quiz

15 Questions

Quiz Description

Physics is a very important branch of science concerned with the nature and properties of matter and energy. The subject matter of these ks3 physics quizzes will include very interesting branches/topics like mechanics, heat, light and other radiation, sound, electricity, magnetism, the structure of atoms, and even more. This particular quiz has several more branches which are going to be seen as you go through the quiz.

To begin, let us look at an overview of what Physics is all about.
Physics has to do with objects, nature interaction, and matter. Physics explains forces, gravity, magnetism, motion, acceleration or speeding up. Physics even goes as far as explaining to us atomic interaction between objects, smallest charges, small masses as well as looks into the universe and galaxy bodies as a whole. Some scientists are experts in Physics, they are called Physicists. 

This quiz will help teach you a lot about so many things, all the questions in this quiz will be from any branch of physics but you can find quizzes of these individual branches under Physics quizzes. This will help you understand Physics concepts even better.  Play the quiz and prepare yourself for any upcoming exams or tests in Physics.
Nice time!

Which statement is FALSE about being trodden on by a stiletto heeled shoe?


Correct
  • 1:
     the smaller the under surface of the stiletto heel, the higher the pressure created
  • 2:
    the stiletto heel causes a high pressure because a significant weight acts on a small surface area
  • 3:
     the stiletto heel produces a low pressure situation
  • 4:
     it is less painful if trodden on by the front part of the shoe, rather than the stiletto heel, because the weight of the person is spread over a larger area

    unlike poles have no effect on each other
  • 4:
     if object x is attacted by a magnet, x must be a magnet
8:

  • 1:
     zinc and iron electrodes
  • 2:
     magnesium and zinc electrodes
  • 3:
    zinc and tin electrodes
  • 4:
    magnesium and silver electrodes
9:

Solar __(1)__ can convert __(2)__ directly into __(3)__ but they are __(4)__. Dark solar panels fitted in a roof, readily __(5)__ radiation to heat water. A curved __(6)__ can also be used to collect and concentrate the heat radiation to cook food on a barbecue!  Which word is missing from __(2)__?


Correct
  • 1:
    cells
  • 2:
    mirror
  • 3:
    absorb
  • 4:
    sunlight
10:

What is the maximum sound level in decibels, you should be exposed to for 3 hours?

  • 1:
    97 dB
  • 2:
    92 dB
  • 3:
    95 dB
  • 4:
    93 dB
11:

Examples to help you get to the point of the question! or do you get a sinking feeling because P = F / A! Which features is designed to reduce the pressure of the situation?


Correct
  • 1:
     the blades of ice skates
  • 2:
     the skis for mountain sports
  • 3:
     the crampons on a mountain climbers boots
  • 4:
     a cheese knife blade
12:

Correct
  • 1:
    aluminium
  • 2:
    iron
  • 3:
    brass
  • 4:
    steel

    hertz
  • 2:
    metres
  • 3:
    meters/second
  • 4:
    decibels
14:

Which is NOT true about a football and football boots?


Correct
  • 1:
     the sole has a much broader area than the studs so the pressure is increased and the boot does not sink into the ground too easily
  • 2:
     the more air that is pumped into a football, the greater the gas pressure
  • 3:
    the studs have a small contact area compared to the sole, to increase the pressure, so they penetrate the ground easily
  • 4:
    if the temperature rises during a match, the plastic of the ball becomes softer and the gas pressure rises
15:
