# At what speed does a meter stick move if its length is observed to shrink to 0.5 m?

## At what speed does a meter stick move if its length is observed to shrink to 0.5 m?

Answer and Explanation: In order to observe a meter stick to shrink its length to 0.5 meters, it must move at a speed of 2.6×108ms 2.6 × 10 8 m s .

## How fast must a Meterstick be moving if its length is measured to shrink to 0.500 m?

Expert-Verified Answer Hence, for the length of the metre stick to be observed to shrink to 0.500m, it must be moving at a rate of roughly 0.866 times the speed of light, or about 259,800 km/s.

## Why does length decrease with speed?

In summary, the size of an object decreases in the same direction it moves. Space contraction refers to the shortening of length at high speeds. Space contraction is negligible at everyday speeds from our perspective. At speeds approaching the speed of light, however, space contraction becomes more pronounced.

## What is a measure of how quickly speed changes with time?

Acceleration – the rate at which velocity changes with time. b. Acceleration is a measure of how quickly the velocity is changing.

## What is the smallest marking on your Meterstick?

Units of Measurement on a Meter Stick The smallest division is millimeter. Millimeter markings are very small. The next larger unit is the centimeter. The entire stick then measures 1 meter.

## Can you use a Meterstick to measure distance in SI units?

New w between object or places. In the United States, we tend to talk about distance and length with inches, feet and miles as the units. In science, the basic [SI unit for length is the meter. We use a meter stick for measuring length.

## What is the measurement that tells us how fast an object is moving?

Speed is the rate at which an object’s position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time.

## What is the formula for time in physics?

The formula for time is given as [Time = Distance ÷ Speed]. To calculate the speed, the time formula will be molded as [Speed = Distance Travelled ÷ Time].

## What is the formula for mass in physics?

The different varieties of ways to determination of the mass of an object are there: (m= ρ/V) Mass = Density/Volume.

## Is speed relative to distance?

One thing all observers agree upon is relative speed. Even though clocks measure different elapsed times for the same process, they still agree that relative speed, which is distance divided by elapsed time, is the same. This implies that distance, too, depends on the observer’s relative motion.

## What is the speed of time called?

There is no speed of time, because time doesn’t move. The term ‘time’ describes our motion through the temporal dimension. So you can ask what is my time speed? (temporal velocity) but the question what is the speed of time? is illogical.

## What is faster light or time?

As far as we know, nothing can go faster than light. However, if one travels close to the speed of light, time behaves differently than we are used to, and in this way, one can move forward in time faster than those left behind. So it is theoretically possible to travel to the future, but one could not return.

## What is the speed rate of change called?

Acceleration is the rate of change of speed. Why some people say it’s true: Think of accelerating in a car: when you hit the gas, you speed up, and when you hit the brake, you slow down. Acceleration is generally associated with a change in speed.

## How fast must a meter stick be moving if its length is observed to shrink to half its original size?

Final answer: The meter stick must be moving at a velocity of approximately 2.71 × 10^8 m/s.

## What is the speed of a moving object determined to be 0.06 m?

So , the answer is 0.216 km/h.

## At what speed should an object move so that its length appears to be half its proper length?

At V = 0.866c or 86.6 % speed of light, the length of the body will become half of its proper length. L is the length observed by an observer when the object is in motion. Lo is the proper length. v is the relative velocity between the observer and the moving object.

## How you can tell from its speed how quickly an object is moving?

Speed is the rate at which an object’s position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time.
