The equation for centripetal acceleration is a = v2/r, where a is acceleration, v is velocity in m/s, and r is the radius of the circle in meters. So the dimension of the acceleration a = (m/s)2/m = m2/s2/m, which gives m/s/s or m/s2. The direction of the acceleration is toward the center of the circle.

No. The velocity of an object is how fast it is moving as well as the direction of the motion. So when considering one dimension, the velocity can be positive or negative. The speed of the object is simply the magnitude (absolute value, in the case of one dimension) of the velocity, with no direction. Acceleration is the change in velocity and does include direction. So if an object has a positive velocity (in one dimension) and its speed increases, the acceleration is negative. However, if the speed of an object moving the negative direction increases, then the acceleration is negative, because the velocity becomes "more negative."

dimensional consistency says that in any equation the dimensions of the quantities in the rhs and lhs are same. for example force =mass*acceleration force dimensions are MLT-2 : mass dimension M ;acceleration dimension LT-2 togehter the right hand side is also having MLT-2 dimension same as that of force.

Because acceleration in physics, is the rate of change of velocity over time. In one dimension, acceleration is the rate at which something speeds up or slows down. The planets are constantly changing direction because of their orbit.

Yes, and the classic example that all mathematics students study is the motion of a projectile. Typically a ball is thrown (or a cannonball fired) at an angle to the horizon and pupils study its trajectory. With some simplifying assumptions, the trajectory is a parabola. Ignoring air resistance (a simplifying assumption), the only acceleration is due to the downward acting force of gravity.

No evidence exists for "alternate dimensions." If they DID exist, no known theoretical framework exists in which acceleration would cause matter in our dimension to go to the other one simply acceleration. In our Universe, acceleration greater than a certain level would cause the death of organic matter. This fatal level has been achieved with death occuring, but no disappearance of the organism -- it simply dies. The idea you suggest is pure fiction, on the same level as magic gremlims.

In SI, acceleration is measured in meters / second2, or meters / second / second. In other units, units of the same dimension have to be used, i.e., [length] / [time] / [time]. For example, in the imperial units, feet per square second is quite common.

Frequency and density aren't involved as 'bare quantities' in force. The bare quantities that constitute force are mass, length, and time, and the physical dimension of force is (mass) x (length)/(time)2 . The 'length' and 'time' combine to result in (length)/(time)2, and that's the 'acceleration' that you did include.

acceleration: "speed variation". the greater the force printed on an object, the greater the variation, the greater the time, the less the variation, therefore, a = f / t.

Consider a graph paper with Axis X and Y. Cart travel in X direction but suddenly, the cart change direction and so it must reduce velocity on X and increase velocity on Y. Net velocity might be the same but small acceleration and deceleration is apply in 2 dimension motion.

The physical dimension of force is [ mass x length/time2 ] or [ mass x acceleration ] . The SI unit is [ kilogram x meter/second2 ] , and is called the "Newton".

As far as I can tell, it's a proprietary connection on the motherboards of the following Dell desktop systems: * Dimension 3100 * Dimension 5000 * Dimension 5100 * Dimension 5150 * Dimension 9100 * Dimension 9150 * Dimension E310 * Dimension E510 * XPS 400

The Third Dimension is the dimension of space, the one we are in now. The Fourth Dimension is the theoretical dimension of time, which overlaps onto the 3'rd Dimension.

The 2 dimension is times 2 but if it is 3 dimension is times 3

There is no equivalence. Per square hour is a measure with dimension [T-2] - which may be used, for example, when measuring acceleration. A second is a measure of time with dimension [T]. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.

Newton's Second Law: force = mass x acceleration Therefore, force = mass x length / time2. In SI units: newton = kg x meter / seconds2.

The fourth dimension.

Lines that define the parameters of a dimension.Dimension lines are thin lines terminating in arrowheads. Place dimension lines no closer than 3/8" from the object outline. Parallel dimension lines should be a minimum of 1/4" apart. You may place parallel dimension lines more than 1/4" apart so long as the spacing between dimension lines is uniform throughout the drawing. Dimension lines are generally broken in the center of the line to provide a space for the dimension figure. Dimension figures for parallel dimension lines are staggered. In some structural or architectural drawings, you may find dimension figures placed above the dimension line.

Velocity??? Are you mad?? The answer is "Acceleration" as explained below.Velocity is not related to "rate of change", but its the speed in a specific direction, its a vector quantity!!The closest answer would be "Acceleration".According to Wikipedia, "acceleration is the change in velocity over time.[1] Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, acceleration is the rate at which something speeds up or slows down. However, as a vector quantity, acceleration is also the rate at which direction changes."Velocity = Speed in a directionSo, acceleration would account for the change in speed as well as the change in direction, with respect to time.
