Question

$v_f = v_i + at$
$d = v_i t + \frac{1}{2}at^2$
$v_f^2 = v_i^2 + 2ad$
these are the...
newtons laws of motion
laws of thermodynamics
kinematics equations
conservation of energy law

Explanation:

The provided equations describe the relationship between initial velocity ($v_i$), final velocity ($v_f$), acceleration ($a$), time ($t$), and displacement ($d$) for motion with constant acceleration, which defines kinematic equations for linear motion. Newton's laws focus on forces and motion causation, thermodynamics laws relate to energy transfer/temperature, and conservation of energy deals with energy transformations, none of which match the given equations.

Answer:

Kinematics equations
