Average Speed. The speed of an object is found out by dividing the distance that the object covers by the time in which the object takes to cover this distance. If 'D' is the distance traveled in some time 'T' then the speed of the object for this journey or 's' is equal to s = D/T. This is the simplest case.

Thus, average Force is equal to the mass of the body multiplied by the average velocity over the defined time. Average Force Formula Questions: 1) A dog that weighs 10 kg chases a car for 12 seconds at a velocity of 5 m/s.

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... The average velocity is the displacement or position change (a vector quantity) per time ratio.

Most uninformed students, when asked to calculate the average speed for a round trip with a “going” average speed of 30 miles per hour and a “returning” average speed of 60 miles per hour would think that their average speed for the entire trip is 45 miles per hour (calculated as (30 + 60) / 2 = 45).

Average velocity is defined as the ratio: displacement divided by time elapsed. It has both magnitude and direction. Average speed is defined as the ratio: distance traveled divided by time elapsed.

Velocity. The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.

The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h).

The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s, or 186000 mi/s).

So the average speed of a gas molecule is about 500 m/sec. This is roughly the speed of sound in a gas 340 m/sec. So the average kinetic energy of the gas molecules is related to the temperature of the gas.

What is the difference between constant, instantaneous, and average speed? constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.

"Acceleration (0-60 mph): 7.0 sec." ... The acceleration of cars in the United States is stated as a "zero to sixty" time, where vi is zero and vf is 60 miles per hour or 27 meters per second. The average rate of acceleration of all the ordinary cars I found was between 3 and 4 m/s2.

A vector quantity is defined by magnitude and direction. For example, we might say that a car has an average speed of 25 miles per hour. Its average velocity might be 25 miles per hour due east. Average speed can be viewed as the rate of change in distance with respect to time.

Velocity facts for kids. Velocity is a measure of how fast something moves in a particular direction. In other words, a velocity is a speed with a direction. For instance, if an object moves east at 7 metres per second (7 m/s), we would say that its velocity is 7 m/s to the east.

The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance. It's a scalar quantity which means it is defined only by magnitude.
