Speed and Velocity
- Speed is a scalar quantity that measures the rate at which an object covers distance. It only has magnitude and no direction. Speed is always positive or zero.
- Velocity is a vector quantity that measures the rate of change of displacement with respect to time. It has both magnitude and direction. Velocity can be positive, negative, or zero.
Differences Between Speed and Velocity
Various differences between Speed and Velocity are added in the table below:
Aspect | Speed | Velocity |
---|---|---|
Quantity Type | Scalar | Vector |
Components | Magnitude only | Magnitude and direction |
Formula | v = d/t | v = Δx/t |
Positive/Negative | Always positive or zero | Can be positive, negative, or zero |
Direction | No direction | Specific direction |
Example | 60 km/hr (without direction) | 60 km/hr north |
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.
