wat moves at constant speed in straight line?
confusing speed with velocity...Mozart said:And I think that when something follows the path of a circle it is said to be constantly changing its speed (accelerating). Although I probably understood this wrong when I heard it.

Kinematics is a branch of physics that studies the motion of objects without considering the forces that cause the motion. It involves analyzing the position, velocity, acceleration, and time of an object in motion.
The basic equations of kinematics are the equations of motion:
- Position: x = x0 + v0t + 1/2at2
- Velocity: v = v0 + at
- Acceleration: a = (v - v0)/t
- Time: t = (v - v0)/a
Kinematics deals with the motion of objects without considering the forces that cause the motion, while dynamics takes into account the forces acting on an object and how they affect its motion.
The three types of motion in kinematics are:
- Uniform motion: when an object covers equal distances in equal intervals of time
- Uniformly accelerated motion: when an object's acceleration remains constant, resulting in a linear increase or decrease in its velocity
- Non-uniform motion: when an object's acceleration changes, resulting in a non-linear change in its velocity
Kinematics is used in various fields, such as engineering, robotics, and sports, to analyze and predict the motion of objects. It is also used in video game development to create realistic movements for characters and objects. In everyday life, kinematics can help us understand and improve our movements, such as in dance or sports, and can also be applied in transportation and navigation systems.
