Kinematics Quiz 1

20 Questions

Quiz Description

In this quiz, we shall study one important aspect of physics known as kinematics. We shall look at velocity, speed, and velocity - time graphs, acceleration, etc. 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 kinematics as a whole.

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 the A level physics quiz, and challenge yourself. Good luck!
