What is the difference between kinematics and dynamics? A quick Google search reveals "dynamic and kinematic viscosity," "kinematic and dynamic performance," "fully dynamic and kinematic voronoi diagrams," "kinematic and reduced-dynamic precise orbit determination," and many other occurrences of this distinction What is the real distinction between kinematics and dynamics?
kinematics - Why is accelerations formulas denominator squared . . . Read it as " (meters per second) per second " The equivalence between " (ms−1) s (m s 1) s " and " ms−2 m s 2 " is a matter of algebra But fundamentally, acceleration is the speed's rate of change You have to take another step to get to position (which is the quantity that you measure in meters) For some students, part of the confusion is that "meters per second" is an unfamiliar unit
kinematics - What does the magnitude of the acceleration mean . . . Your question is kind of vague but I will try to respond Acceleration is defined as the time rate of change of velocity Since velocity has both magnitude and direction, so does acceleration In other words, acceleration is a vector The length of the vector is its magnitude Its direction is the direction of the vector So the magnitude of acceleration is the magnitude of the acceleration
kinematics - How to remove gravity component from accelerometer $X$, $Y . . . If the accelerometer is placed flat on a table, then x and y would be parallel to the table, and the z axis perpendicular So, effectively I'm looking to remove the acceleration component in the x and y axes due to gravity when the device is not flat (some roll and pitch) So that when stationary I should get close to 0 values for any arbitrary orientation
kinematics - Minimum launching speed projectile constraint - Physics . . . I came across an interesting lemma in page-9 of Jaan Kalda's Kinematics handouts, the following is written: When a target is shot with the smallest possible launching speed, the trajectory and the shooting range boundary (corresponding to the launching speed) are tangent to each other at the target’s position
kinematics - Galileos law of odd numbers - Physics Stack Exchange The Galileo’s law of odd numbers states that the distances traveled are proportional to the squares of the elapsed times In other words, in equal successive periods of time, the distances traveled
kinematics - Radius of curvature - Physics Stack Exchange I have come across a question that asked me to find the radius of curvature of a projectile As far as I know, the path of a projectile is a parabola and I have found mention of the radius of curv
kinematics - Calculating Average Velocity - Physics Stack Exchange This will provide you with the value for the average of any number of values Similarly there is a formula in physics that calculates the average velocity from a graph by dividing the sum of the initial and final velocities by 2
kinematics - What does instantaneous displacement really mean . . . I get the same answer since i've taken c as zero, but if c has any other value, my answer differs by c c So is displacement really the change in position from the origin? I've never thought of it in that way, rather the change in position from the original position of the object
friction - Kinematics of an object placed on a treadmill - Physics . . . 0 It has been quite some time since I've done even basic kinematics, as my background is in mathematics, rather than physics, and I am at embarrassed how dumbfounded I am at formulating the equations of kinematics for an object placed on a treadmill In this diagram, we have an object of mass m m placed on a surface moving at a constant
