Simply stated, acceleration is the ability of an object to gain speed. Play this informative physics quiz on motion with constant acceleration and find out much you know about the topic. This quiz covers numerical equations, basic definitions, concepts, and other factual information regarding motion...
The equation v¯=v0+v2v¯=2v0+v reflects the fact that, when acceleration is constant, v is just the simple average of the initial and final velocities. For example, if you steadily increase your velocity (that is, with constant acceleration) from 30 to 60 ...

X.U.V.A.T. “EQUATIONS OF MOTION UNDER CONSTANT ACCELERATION” VARIABLES: x displacement (since initial time)..
average acceleration (at an interval) instantaneous acceleration (at an instant) v is the velocity and t is the time equation of motion for constant acceleration v=u + at s= ut + ½ at 2 v 2 = u 2 + 2as s = {(u+v)/2}t for a freely falling bodies (u=0) v =-gt s= ...
The first equation comes from the idea of average acceleration, which is like average velocity a―=v−v0t−t0 If we assume that t0=0 and that acceleration is constant, then we can write it like this: a=v−v0t Solved for v, this is the first equation: v=v0+atApplication...
(a) has fallen to zero. Simple harmonic motion ischaracterizedby this changing acceleration that always is directed toward the equilibrium position and is proportional to the displacement from the equilibrium position. Furthermore, the interval oftimefor each complete vibration is constant and does ...
For example, a falling body accelerates at a constant rate, g. Acceleration is the rate of change of velocity with respect to time, so that by integration the velocity v in terms of time t is given by v = gt. Velocity is the time rate of change of position S, and, consequently, ...
f(vz)=constant×e−mrz2/2kT. [It should be noted that the acceleration due to gravity does not appear in this formula. This is as it should be, since the mechanism of establishment of the velocity distribution of the gas molecules consists in collisions between molecules and does not dep...
Newton’s First Law of Motion: The law of inertia states that an object at rest will remain at rest, and an object in motion will continue moving with a constant velocity, unless acted upon by an external force. Newton’s Second Law of Motion: This law relates the force acting on an ...
