Speed is the ratio of the distance an object moves to?
speed is the ratio of the distance an object moves per time unit (seconds,minutes hours)
What is the formula for calculating time when you know the initail speed final speed and the distance?
Time = Distance / Speed "/" means divide Calculate the average speed then put it into the equation. For example: Time (hours) = 42 miles / 86 miles per hour Time = 0.49 hours Time = 29.4 minutes (60x0.49)
Determine the units of a caterpillar's speed if you measure the distance the catapillar travels in centimeters and the time it takes to travel this distance in minutes?
determine the units of a caterpillar's speed if you measure the distance the caterpillar travels in centimeters and the time it takes to travels this distance in minute
Relationship between time and distance?
distance = speed x time For example if you travel 50 miles per hour for two hours, the distance is 100 miles
What is tangential speed?
Linear speed is the distance traveled per unit of time, while tangential speed (or tangential velocity) is the linear speed of something moving along a circular path.[5] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point nearer the center. Traveling a greater distance in the same time means a greater speed, and so linear speed is greater on the outer edge of a rotating object than it is closer to the axis. This speed along a circular path is known as tangential speed because the direction of motion is tangentto the circumference of the circle. For circular motion, the terms linear speed and tangential speed are used interchangeably, and both use units of m/s, km/h, and others.Rotational speed (or angular speed) involves the number of revolutions per unit of time. All parts of a rigid merry-go-round or turntable turn about the axis of rotation in the same amount of time. Thus, all parts share the same rate of rotation, or the same number of rotations or revolutions per unit of time. It is common to express rotational rates in revolutions per minute (RPM) or in terms of the number of "radians" turned in a unit of time. There are little more than 6 radians in a full rotation (2π radians exactly). When a direction is assigned to rotational speed, it is known as rotational velocity or angular velocity. Rotational velocity is a vector whose magnitude is the rotational speed.Tangential speed and rotational speed are related: the greater the RPM's, the larger the speed in meters per second. Tangential speed is directly proportional to rotational speed at any fixed distance from the axis of rotation.[6] However, tangential speed, unlike rotational speed, depends on radial distance (the distance from the axis). For a platform rotating with a fixed rotational speed, the tangential speed in the center is zero. Towards the edge of the platform the tangential speed increases proportional to the distance from the axis.[7] In equation form:where v is tangential speed and ω (Greek letter omega) is rotational speed. One moves faster if the rate of rotation increases (a larger value for ω), and one also moves faster if movement farther from the axis occurs (a larger value for r). Move twice as far from the rotational axis at the center and you move twice as fast. Move out three times as far and you have three times as much tangential speed. In any kind of rotating system, tangential speed depends on how far you are from the axis of rotation.When proper units are used for tangential speed v, rotational speed ω, and radial distance r, the direct proportion of v to both r and ω becomes the exact equationThus, tangential speed will be directly proportional to rwhen all parts of a system simultaneously have the same ω, as for a wheel, disk, or rigid wand. (The direct proportionality of vto r is not valid for planets, because planets have different rotational speeds).
What does distance times velocity or time equal?
it = speed over time
Formula of speed?
Speed is equal to the change in distance over the change in time, or V = D/T where V is speed, D is distance and T is time.
Is Speed is equal to distance divided by time?
Average speed is equal to the total distance travelled divided by total time.
What are time distance graphs?
On a distance-time graph, the gradient of the line is numerically equal to the speed. therefore if you get the rise over the run you should be able to calculate the speed traveled at.
What speed means equal distances are covered in equal times?
Since speed is a function of distance over time, then if both distances and times are equal, then the speed must be the same in both cases.
How are speed and distance directly related?
They are related over the time. Speed x time = distance.They are related over the time. Speed x time = distance.They are related over the time. Speed x time = distance.They are related over the time. Speed x time = distance.
When an object covers equal distance in equal amounts of time?
When an object travels covers equal distances in equal amount of time it can be said that it is traveling with constant speed. speed = distance/time. Unit of speed is m/sec. speed is a scalar quantity.
Is the average speed equal to distance divided by time?
yes, the average speed equals distance divided by time
Relate speed to distance and time?
distance over time equals the speed/velocity.
Formula of time?
You can find many formulas in which time is one of the variables. For example, the distance formula states that distance is equal to speed multiplied by the time. You can find time by saying that it is equal to distance divided by speed.
How do you do average speed for math?
Average speed is simply the total distance traveled over the time taken to travel that distance, then you change the fraction to equal distance over 1 hour, 1 min, 1 sec, ect.
How is speed measured?
Speed is measured by calculating the distance you have gone and how long it took you to get there. speed = distance over time
