What are the kinematic equations?
V = Vo + at
X - Xo = Vot + .5at2
v2 = vo2 + 2a(X - Xo)
X - Xo = .5(Vo + V)t
V is final velocity in units of meters per seconds (m/s)
Vo is initial velocity in units of meters per seconds (m/s)
a is acceleration in units of meters per squared seconds (m/s2)
t is time in seconds (s)
X is final displacement in units of meters (m)
Xo is initial displacement in units of meters (m)
Multiple unknowns can be solved for each other by using more than one equation. If you are solving for two components, find a common piece (such as time), solve for that piece for each component and set them equal to each other to solve for the other unknowns.
Hope this helps!
p.s. sometimes it is easier to remember the second, third and fourth equations as
2. df - dI = vIt + .5at2
3. v2=vI2+2a(df - di)
4. df - dI = .5(vI + vf)t
its all the same except x has been switched with the first letter of displacement, and the 0 have been switched with i for initial. f is for final

Is the kinematics equations true if acceleration is not uniform?
The answer is "No". If acceleration changes, forces of inertia should be taken to consideration. It requires dynamic equations of motion. However, if acceleration changes are …not significant, you may continue using kinematics. To check if kinematic solution is within required precision limits you need to compare the solution of kinematic and dynamic equations and decide if kinematic solution is good enough. (MORE)

What is meant by kinematic equation of motion?
Simply put, kinematics is really just physics without forces or masses. Â That is, you deal with velocities, accelerations, time, etc. Â So a kinematic equation will have thos…e variables. The kinematic equation of motion could be any of the four equations I list, or any variation of them (they can be rewritten in a number of ways): let d = distance, v = velocity, i = initial velocity, a = acceleration, t = time v = i + atd = it + (1/2)t2 v2 = i2 + 2add = (1/2)(i + v)t The equations describe the motion, whether it describing it's acceleration, velocity, distance traveled along a certain axis, all with respect to time.

Can kinematics equations bs used in situation in which the acceleration is zero?
Yes. The kinematics eqs. can be used whenever the acceleration is constant (magnitude & direction) and zero is certainly a valid constant acceleration. The eqs become pretty s…imple in that case but they are correct. (MORE)

What are the differences between kinematics and dynamics?
Kinematics does not take forces explicitly into account. Instead, kinematics works with the motion of objects (speed or velocity). Dynamics will take forces into account expli…citly. Common examples of the two would be projectile motion of objects (constant acceleration equations) and Newtonian dynamics (Newtons three laws...the second law is the sum of the forces). (MORE)

Who is invented in kinematics?
Well obviously the person that was invented in kinematics is the massless, omniscient observer that calmly puts all the objects into motion instantaneously without considerati…on for past history or all other objects in the universe. If the question had been "Who invented kinematics?". Well, really there is no one answer for that. Since kinematics is the study of motion and objects, humans have been doing that since the beginning of time. But who really started to scientifically analyze and put these observations onto paper? One of the most famous observer had been Galileo, who conducted many of the same experiments that physics students love doing experiments on. For instance, he observed that balls rolling down ramps traveled intervals of squared proportions (1, 4, 9, etc.) and he extrapolated that this held true for free falling objects too (though harder to observer without the technology of photography). Another famous experiment was the pendulum experiment, in which he measured rather accurately the periods of pendulums of various size and length, and observed many of the fundamental consequences that we take for granted (i.e. period of a pendulum is independent of weight and amplitude). But what really set in stone the study of kinematics was the work done by Newton, which introduced mechanics (or force analysis), and Calculus (yes, yes, Leibniz too) and kinematics became a relatively well defined field of physics.
