Key Concept in Kinematics
Kinematics is a branch of mechanics that describes the motion of objects without considering the causes of this motion (i.e., forces). It involves the study of displacement, velocity, and acceleration of moving objects.
Displacement: Displacement is a vector quantity that refers to the change in position of an object. It has both magnitude and direction.
Δx = xf – xi
where,
- xf is the Final Position
- xi is the Initial Position
Velocity: Velocity is a vector quantity that denotes the rate of change of displacement with respect to time. It includes both speed and direction.
vavg = Δx/Δt
where,
- Δx is Displacement
- Δt is the Time Interval
Acceleration: Acceleration is a vector quantity that represents the rate of change of velocity with respect to time.
aavg = Δv/Δt
where,
- Δv is Change in Velocity
- Δt is the Time Interval
Relative Motion: Relative motion describes the motion of an object as observed from a particular frame of reference.
Kinematics | Definition, Formula, Derivation, Problems
Kinematics is the study of motion of points, objects, and systems by examining their motion from a geometric perspective, without focusing on the forces that cause such movements or the physical characteristics of the objects involved. This study area uses algebra to create mathematical models that describe these motions, essentially treating it as the mathematics behind how things move.
Kinematics is a field of classical mechanics that deals with the motion of points, objects, and systems of objects. Kinematics is sometimes referred to as “motion geometry” by some professionals. Let’s have a look at the formula for kinematics.
In this article, we shall learn about kinematics, which is the study of motion, along with its formulas, derivation of kinematics formula, examples and others in detail.
