The study of motion of objects without the reference of force and mass is called...?
Kinematics is the branch of physics that deals with the study of motion, specifically the description and analysis of the movement of objects without consideration of the causes of the motion.
The basic concepts of kinematics include position, displacement, velocity, acceleration, and time. Position refers to the location of an object in space, while displacement is the change in position over time. Velocity is the rate of change of displacement, and acceleration is the rate of change of velocity. Time is the duration of the motion.
Speed and velocity are often used interchangeably, but they have different meanings in kinematics. Speed refers to the rate at which an object is moving, while velocity takes into account the direction of the motion as well. Velocity is a vector quantity, meaning it has both magnitude and direction.
Acceleration is calculated by dividing the change in velocity by the change in time. The formula for acceleration is a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
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. Average velocity is a constant value over a given interval, while instantaneous velocity can change at any given moment.
