- If the object is speeding up, then its acceleration vector is directed in the same direction as its motion (in this case, a positive acceleration). ... The velocity-time graph shows a line with a positive (upward) slope (meaning that there is a positive acceleration); the line is located in the positive region of the graph (corresponding to a positive velocity). The acceleration-time graph shows a horizontal line in the positive region of the graph (meaning a positive acceleration).

15. Newton's Three Laws of Motion
- csep10.phys.utk.edu
- The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. ...
- Notice the fundamental difference between Newton's 2nd Law and the dynamics of Aristotle: according to Newton, a force causes only a change in velocity (an acceleration); it does not maintain the velocity as Aristotle held. ...
- Thus, according to Aristotle there is only a velocity if there is a force, but according to Newton an object with a certain velocity maintains that velocity unless a force acts on it to cause an acceleration (that is, a change in the velocity). ...

- Acceleration: Is moving ahead the right step? .
- But some psychologists' research shows that acceleration--skipping grades or working ahead in a particular subject--can be one of the best methods to meet the needs of gifted youth. While not a panacea, acceleration gives students access to true peers and challenging work, say a number of experts. ...
- That's why acceleration decisions should be made on a case-by-case basis, say experts such as Susan Assouline, PhD, and Nick Colangelo, PhD, who have developed the Iowa Acceleration Scale, a tool to help parents and educators make such decisions. ...
- For example, acceleration may not be right for a gifted student who is also a stand-out football player or isn't socially mature. And others may need acceleration in only one area, since many gifted children develop asynchronously. ...
- Moreover, some caution against looking at acceleration as just moving ahead. ...
- But gifted students who don't receive some kind of enrichment--whether it's acceleration or a supplemental program--are less likely to excel. ...

19. Non-coordinate time/velocity pairs
- www.umsl.edu
- Such coexisting kinematics provide alternate variables to describe acceleration. ... For example, Galileo's acceleration equations describe unidirectional relativistic motion exactly if one uses V=dx/dT, where x is map-frame position and T is clock time in a chase plane moving such that gamma' = gamma Sqrt 2/(gamma+1) . ...
- The equations for constant proper acceleration look quite different in the traveler kinematic, although they too have been rarely discussed (except for example in the first edition of the classic text by Taylor and Wheeler{TaylorWheeler}). ...
- For unidirectional motion, Galileo's equations for constant acceleration exactly describe relativistic motions for our traveler in such a kinematic. ... For non-unidirectional motion, however, the constant acceleration equations containing Galilean-observer time look more like elliptic integrals than like Galileo's original equations.
- Since all kinematics share common distance measures in the context of one inertial reference frame, they allow one to construct x-tv plots showing all variables in the context of that frame, including universal constant proper acceleration surfaces on which all flat space-time problems of this sort plot. ...
- What follows is a look at the equations provided by each of these kinematics for describing map trajectories for our traveler under constant proper acceleration alpha.
- Constant proper acceleration.
- The frame-invariant proper acceleration is most simply described with some definitions in 4-vector notation. If one writes the traveler 4-vector position as X = {cb,x,y,z}, then traveler 4-velocity is U = dX/dtau = {c gamma, ux, uy, uz}, and the 4-acceleration is A = dU/dtau = (1/m) {(1/c)dE/dtau, Fx, Fy, Fz} where Fi = dpi/dtau denotes the proper force (traveler-time derivative of traveler momentum) in the i direction, and E total relativistic energy, with respect to the map frame. Flat space-time dot products, formed by subtracting the sum of squares of the last three components from the square of the first component, include dX*dX = c^2 db^2-dx^2-dy^2-dz^2=dtau^2, U*U = c^2, A*U = 0, and A*A = -alpha^2, where alpha is the traveler's frame-invariant proper acceleration.
- With no loss of generality, let's define x as the ''direction of proper acceleration''. ...
- A first integral of the motion, which is independent of kinematic, is helpful for exploring intra-kinematic solutions of the constant acceleration equation. ... This is nothing more than the work-energy theorem for constant proper acceleration, which takes the form gammay m alpha Delta x = Delta E = mc^2 Delta gamma . ...
- For the coordinate-kinematic case, V = w and T = b, so that putting gamma V from Table 1 above into the work-energy theorem above provides a constant acceleration equation relating w to x. ... Note in particular that the simplest result is found using the Galilean kinematic, wherein the full and familiar set of Galilean constant acceleration equations become available for the solving of relativistic acceleration problems. ...
