Vectors Vs Scalars, Displacement, Distance, Velocity, Speed, Acceleration - Physics (Mechanics)

Kinematics quantities are the fundamental concepts used to describe the motion of objects, including position (or displacement), velocity, acceleration, and time. They can be related through kinematic equations to analyze motion without considering the forces causing it. A more advanced quantity is jerk, which is the rate of change of acceleration.

💡Key kinematics quantities
• Displacement (\(s\) or \(\Delta x\)): The change in an object's position. It is a vector quantity, meaning it includes both magnitude and direction.
• Velocity (\(v\)): The rate of change of displacement with respect to time. It is a vector quantity that describes both speed and direction.
• Acceleration (\(a\)): The rate of change of velocity with respect to time. It is also a vector quantity.
• Time (\(t\)): The duration of the motion being analyzed.
• Initial velocity (\(u\) or \(v_{0}\)): The velocity of an object at the beginning of the time interval being studied.
• Final velocity (\(v\) or \(v_{f}\)): The velocity of an object at the end of the time interval being studied.
• Jerk: The rate of change of acceleration with respect to time, which becomes relevant when forces are changing.

💡Relationship to forces
Kinematics describes motion on its own, separate from the forces that cause it. However, acceleration is directly caused by the net force acting on an object, according to Newton's laws of motion.
