Basics Kinematics
Continue reading the Original PF Insights Post.
Basic kinematics is a branch of physics that studies the motion of objects without considering the forces causing the motion. It focuses on describing the position, velocity, and acceleration of objects in motion.
Scalar quantities only have magnitude, such as distance or speed, while vector quantities have both magnitude and direction, such as displacement or velocity.
Displacement is a vector quantity that refers to the change in position of an object from its starting point to its ending point, taking into account direction. Distance, on the other hand, is a scalar quantity that refers to the total length traveled by an object.
Average velocity is the total displacement of an object divided by the total time taken, while instantaneous velocity is the velocity of an object at a specific moment in time.
Acceleration is the rate of change of an object's velocity over time. If an object is accelerating, it means its velocity is changing, either by increasing or decreasing. This can cause a change in the object's speed or direction of motion.
