In classical physics, we have the Newton equation for a particle F = dp/dt,
where F is force and p the linear momentum (p = m dr/dt). Assuming that mass m is constant, we can rewrite the N. eq. as F = m d2r/dt2.
Knowing F on the particle, the study of motions consists in the integration of the Newton's second order differential equation, obtaining
r = r(t), called motion equation, that describes the position of the particle in function of the time: to study the motion of the particles means to find this r(t). (Note that, in the integration of N. eq., two constants appear: you can calculate them by imposing the boundary conditions, e.g. r(0) and dr(0)/dt). For example, you may study the motion of a particle with F = gmx, being g a constant and x a versor. It's g = d2x/dt2 → ∫g dt = ∫d2x/dt2 dt → gt - gt0 = dx(t)/dt - dx(0)/dt; if t0 = 0 and dx(0)/dt = v0, it's dx(t)/dt = v0 + gt → ∫dx/dt dt = ∫v0 + gt → x(t) - x(0) = v0t + gt2/2;
if x(0) = x0, we have the motion equation of the particle: x(t) = x0 + v0t + gt2/2.
If there are N particles, you will have to solve a N. eq. for each one: a system of N equations! (See statistical mechanics).
Otherwise, you can use Euler-Lagrange equation instead of Newton equation, that doesn't need F, but kinetic and potential energy, T and V (using scalars, and not vectors). (See analytical mechanics).
In quantum mechanics the situation gets more complex, involving the Schroedinger equation.
the study of this is called physics which is studied by a physicist.
motion
The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it.
Biomechanics is the study and application of the principles of physics applied to human motion. A pull, tear, or rip in a muscle or tendon is known as a strain.
kinematics
Inertia
study of motion
motion
In physics we call it kinematics :) Hope this helps.
I believe it's the study of moving objects.
kinematics
The study of why objects move is dynamics, whereas the study of how objects move is kinematics.

Mechanics and Kinematics.
In physics we call it kinematics :) Hope this helps.
kinematics
No, kinematics specifically refers to the study of motion. If an object is at rest, there is no motion occurring, and therefore no kinematics.
The study of matter in motion is commonly called kinematics.
Kinematics
I believe it's the study of moving objects.
kinematics... apex physical science.
