Gravity and space quiz

16 Questions

Quiz Description

In this quiz, we will be looking at Space and Gravity. This quiz will boost your knowledge of the part of the universe. Gravity is said to be a fundamental force of nature, it has so many advantages, for, without gravity, there will be nothing to hold the planets in place. Life itself on Earth is because of gravity, without gravity, you wouldn’t be able to move, on the ground, nor would the Earth be in its position. We will experience what is called weightlessness if there were no gravity. Along the line of the quiz, you will learn about Newton’s universal gravitational law.

Gravity, also known as gravitation, is the universal force of attraction acting between all matter. Newton's law of universal gravitation

Newton's law of universal gravitation is usually stated as every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers (that is the distance separating the 2 centers of masses). 

space on the other hand is that zone above and around our planet where there is no air to breathe or to scatter light, space, is almost a vacuum just because it is nearly empty. So simply, space is a vacuum, but it is far from empty.

Our father of science,  Einstein connected the dots to suggest that gravity is the warping of space and time. So gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel.  And this is the relationship between gravity and space.
In this quiz, you are required to have knowledge about space. This is a very important part of real-life physics, the universe revolves around gravity and space which therefore means that we are very dependent on these two things for survival. Make sure you take this quiz very seriously, it forms the basis of science itself, and luckily for you, our quizzes are more on both science and Art.
GOOD LUCK TO YOU!

     the astronaut's mass on the Moon is about 11.3kg
  • 4:
     the astronaut's mass is zero half way to the moon
6:

The earliest theories on falling objects suggested that the heavier the object, the faster it falls. We now know that all objects fall at the same speed if only the force of gravity is acting on the object. If the following four objects were dropped from 10 metres above the Earth's surface, at the same time,The earliest theories on falling objects suggested that the heavier the object, the faster it falls. We now know that all objects fall at the same speed if only the force of gravity is acting on the object. If the following four objects were dropped from 10 metres above the Earth's surface, and the experiment repeated on the Moon, which statement is most likely to be FALSE?


Correct
  • 1:
      the best fair test of the effects of air resistance, would be to compare the fall of the pool ball and the hammer
  • 2:
     objects like feathers, fall more slowly on Earth than most other objects, because they have a such a small mass
  • 3:
     compared to Earth, all the objects would fall faster on Jupiter
  • 4:
     different objects fall at different speeds on the Earth due to the effect of shape on the air-resistance force
7:

Which statement is FALSE about the force of gravitational attraction?


Correct
  • 1:
      it only acts around the surface of an object
  • 2:
    it happens between all objects
  • 3:
      it decreases if the distance between objects increases
  • 4:
     it is larger if the mass of an object is larger
8:

We now know that all objects fall at the same speed if only the force of gravity is acting on the object. If the following four objects were dropped from 10 metres above the Earth's surface, at the same time,The earliest theories on falling objects suggested that the heavier the object, the faster it falls. We now know that all objects fall at the same speed if only the force of gravity is acting on the object. If the following four objects were dropped from 10 metres above the Earth's surface, and the experiment repeated on the Moon, which statement is most likely to be FALSE?


Correct
  • 1:
     when an object falls to the surface of the Moon, only the force of gravity affects the object
  • 2:
      all objects fall in the same time on the Moon because there is no atmosphere to cause a friction effect
  • 3:
      objects fall faster on the Moon than on Earth because the Earth has an atmosphere which causes an opposing air-resistance force

     when an object falls to the surface of the Earth, the forces of gravity and friction affect the object
