What is the relationship between energy and the speed?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
If a machine multiplies force by a factor of four what other quantity is diminished and by how much?
the distance is diminished by a factor of 4.

Is instantaneous velocity speed?
Instantaneous velocity is the rate of change of displacement at a particular time in the course of motion. Speed is the overall rate of change of distance for an entire journey calculated by dividing total distance travelled by total time spent during the motion.
How can you study speed by using a graph?
One side of graph is time Other side is distance
What other factor is speed by distance over?
Time
How is speed calculated on water?
The same way it is calculated for travel through any other medium. Distance divided by time.
Is it true that speed is calculated by dividing Time by Distance?
It is the inverse of that: you divide distance by time to find speed (rate of movement). Some common units are meters per sec (m/sec) and miles per hour (mph).
How is speed related to time and distance?
Speed, distance and time are related to each other because, speed is directly comparable to distance when time is constant.

Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
What is an Rf factor and how is it calculated?
The Rf value is the "ratio to the front." Hence the R and the f. It is defined as the ration of the distance traveled by a spot (measured from the center) to the distance traveled by the solvent.
How speed distance and time of a moving object related to each other?
In the case of constant speed: distance = speed x time For variable speed: speed = ds/dt, where "s" is the object's position.
What is the formula for finding the distance and time from the speed?
Distance = (speed) multiplied by (time)Speed = (distance) divided by (time)Time = (distance) divided by (speed)These three formulas are all equivalent ... knowing any one of them, you can easily write the other two.What they show you is that in order to find the distance OR the speed OR the time, you have to knowboth of the other two quantities.The answer to your question is: If you only know the speed, then you CAN'T find the distance AND the time.This makes sense: You can have a million cars all driving at the same speed. That certainly doesn't meanthat they all drive for same length of time and cover the same distance, does it ? ! ?
Can you give me examples of problems involving inverse proportion?
Inverse proportions appear in many different contexts. Here are some examples:Several relationships in the ideal gas law. For example, if you increase the pressure of an ideal gas by a certain factor, its volume will decrease by the same factor. The behavior of real gases tends to be close to that of the ideal gas, under most circumstances.If you increase the number of people doing a certain job by a certain factor, the time it takes should decrease by the same factor. This, of course, assumes that all the people you add will be just as productive, and won't interfere with one another.In speed problems, distance = time x speed. Solving for time, you get time = distance / speed. Thus, if you increase the speed, you'll decrease the time it takes.Similarly, if you solve the speed equation for speed, you get speed = distance / time. Thus, if you increase the time allowed to get to a certain destination, you reduce the speed at which you must travel.In general, when one quantity is the product of two other quantities (as in the speed case above), you can always solve for one of the other two variables, to get an inverse proportion.
If a machine multiplies force by a factor of four what other quantity is diminished and by how much?
the distance is diminished by a factor of 4.
Principle involved in distance and time?
Distance and time mostly go together. And speed also goes along with these two. Below are some equations related to distance and time: Time = Distance / Speed Distance = Time * Speed Speed = Distance / Time From this we can see that if any one of these three measurements are changed, one of the other two or both will always change.
