Kinematics is the area of Dynamics that you would use to study geometric aspects of motion. You can use kinematics to study the motion of a particle or the motion of a rigid body. For this section I will be focusing on kinematics of a particle.
A particle is an object that has a mass but its size and shape are negligible. This means we won’t have to consider any translations or rotations of the individual particle like we would for a rigid body. Instead we only need to consider the path of motion for the particle.
When looking at the path of motion of a particle we will have to consider particles displacement, particles velocity, and particles acceleration. We will also need to see how these can be related to time. The path of motion could be in a strait line, or it could be rotational. Depending on which will determine how you would look at the problem and ultimately solve it. Finally how different particles can influence each other will also be studied.
The first thing that you should look at is particle displacement. Continue to the next article to learn more.
