Kinematics Quiz 2

20 Questions

Quiz Description

In this second quiz, we shall go deeper into the study of kinematics. More emphasis will be laid on speed and velocity - time graphs and terminal velocity. Graphs are something very common you would find in this topic, implying that knowing it to your fingertips is a plus for you. Answering the quiz will give you an upper hand in the understanding of graph analysis and the fundamentals of kinematics.

Kinematics is a branch of mechanics that studies the motion of a point, body, or group of objects, without considering the cause of the motion. This topic greatly focuses on aspects like acceleration and velocity. To describe the motion of celestial bodies, astrophysicists make use of kinematics. Kinematics could also be applied in biomechanics by describing the motion of the skeletal system. 

Now we have come to realize how important this quiz is to anyone studying kinematics. Are you looking for a way of understanding this topic? All you need to do is take this A level physics quiz and challenge yourself. Good luck!
