A level Center of Gravity Quiz 1

15 Questions

Quiz Description

As we all probably know, gravity is the attractive force that the planet earth exerts on a body which is close to or on it. This quiz, a level center of gravity quiz, has questions which have been set based on the national curriculum for the gce at the advanced level.

You must have heard someone say that there are advantages to being short when it comes to stability. That is very true and this is due to the position of the center of gravity of the body. The center of gravity (sometimes denoted CG) of an object is simply the point at which all of the weight of the object seems to be concentrated. The center of gravity of a human being varies with its size but for many other objects, the center of gravity is at a fixed location.

As a physics student, you need to understand this topic as it is very vital in the study of physics. If you’re facing difficulties, don’t bother, this quiz is here to guide you. Good luck.
