In this quiz, we shall take a look at Mechanics, and a lot of exciting concepts like forces, velocity, dimensions, etc will be reviewed with the aid of the following questions. You will be guided through the journey of mastering the topic as you practice along.
Mechanics is one of the major branches of physics, and it is concerned with the motion of physical objects or bodies. To be more specific, mechanics studies the relationship between forces, motion, and matter. Forces are applied on bodies and cause them to either begin the motion, end motion, or change direction in motion. Notwithstanding, there are two branches of mechanics which are classical and quantum. Classical being concerned with the motion of bodies under the influence of a force or forces, and Quantum mechanics dealing with the explanation of the functioning of the universe at a scale smaller than atoms.
A physical equation is dimensionally homogeneous when:
The method of dimensions
A graph cannot be used to
