What is kinematics? ⛄

Kinematics is the study of motion of a system of bodies without directly considering the forces or potential fields affecting the motion. In other words, kinematics examines how the momentum and energy are shared among interacting bodies.

VariableKinematic variables allow the description of the motion of a body without reference to variables that act to change the motion of the body. The variables that act to change the motion of a body, kinetic variables, will be covered elsewhere.PurposeThe kinematic equations are a set of four equations that can be utilized to predict unknown information about an object's motion if other information is known.

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
