∙ 9y agoThe ratio of distance at which an object is moving to time refers to its speed. A high speed means that the object covers a long distance within a short time.

What is the mechanical advantage of an inclined plane that is vertical?
It is equal to the ratio of the load divided by the distance of the fulcrum.
Why might compound gear train be better than two gears alone?
Because the speed is decreased less from an equal gear ratio.
How Does Valve Work?
u mean valve of a engine.....? here's the answer... when the crankshaft rotates,then with the help of timing gear the camshaft rotates.timing gears are the gears on crankshaft(pinion) and camshaft(gear). when the cams on the crankshaft rotates it lifts up the follower(during eccentric portion of the cam). follower is connected to a push rod which moves the rocker about a point. rocker presses the valve stem in avalve guide againt the spring pressure. the valve comes down from the valve seat. and our fuel air mixture rushes inside the cylnder. when the non eccentric portion of the cam on the camshaft comes valve stem moves up due to spring pressure. the timing gears are such that they maintain a speed ratio of two between them. it means camshaft has to rotate at half the speed of crankshaft. it is because a valve has to open and close once in every two revolutions of the crankshaft.

What is bypass ratio in gas turbine engine?
bypass ratio im an early singlr or twin-spool bypass engine is the ratio of cool air mass flow passed through the bypass duct to the air mass flow passed the high pressure system. Bypass ratio for the fan ducted bypass engine is the ratio of total air mass flow through the air fan stage to the air mass flow that passes through the turbine section/high pressure(engine core) system.A high bypass ratio i.e 5:1 is usually common with ducted fan engine.
How do you find the speed of an object?
The speed of an object at a time is found by determining its rate of change of distance. If the speed is constant, it can be determined by the ratio of distance to time taken.
How do you find speed ratio?
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
What is speed a ratio of?
Distance and time.
In a distance-time graph the slope of is the ratio of time to distance?
no it's the ratio of distance to time (ie speed)
What is the definiton of magnification?
It's a ratio of Image distance to the Object distance.
A ratio of distance over time is what?
SPEED
What is the ratio of distance travelled to time?
It is the average speed.
How to calculate the average speed of a bus?
The average speed is the ratio between the distance and time.
In what unit is velocity measured?
Velocity is the ratio of two fundamental physical quantities: distance and time, and iscomputed as the distance an object moves divided by the time in which it moves. InSI units distance is measured in meters, and time in seconds. Therefore in SI unitsvelocity is measured in meters/sec. However velocity can be measured in any unitsof distance per time: miles/hour, inches/year, micrometers/decade. As long as youhave a unit of distance in the numerator and a unit of time in the denominator youhave an acceptable unit for velocity.So far, to this point, what you have is the sizeof the velocity, also called "speed".To make a velocity out of a speed, you must indicate the direction of the speed.
How do I calculate the distance between current location and a distant visible object if the only information available is the height of the object and the distance between 2 fingers at your eye?
The ratio of the spacing of the fingers and the distance from your eye will be the same as the ratio of the height of the object to its distance from you, so Hf/Df = Ho/Do and Do = HoDf/Hf
What is the numerical ratio of displacement to distance for a moving object?
1 is to 1
How can ratio and a fraction be different?
A fraction is a ratio of two quantities which are measured in the same units. In a simple case, average speed is the ratio between the distance travelled and the time taken. However, the speed is not a fraction of wither the distance nor of the time.
