What is the average velocity of a particle when it returns to the straight point?
The average velocity of a particle when it returns to the starting point is zero. This is because velocity is a vector quantity that includes both magnitude and direction, and returning to the starting point means the displacement is zero, resulting in an average velocity of zero.
When does the avg velocity become 0?
Average velocity is 0 when an object returns to its starting point after moving away from it. This means that the total displacement of the object is 0, resulting in an average velocity of 0.
When does the average velocity become zero?
The average velocity becomes zero when an object returns to its initial position after moving in a straight line. This happens when the displacement is zero over a period of time.
If a train goes 95 km per hour for 250 km and returns at 65km per hour for 250 km what is the average velocity?
You can't calculate the average of 95 and 65 in this case - the answer will be slightly off. Instead, calculate the time the train took to go one way, and the time it took to go back. Then divide the total distance by the total time. This will give you the average SPEED. (Average VELOCITY will be zero, since the train gets back to its starting point.)
What is an example of average velocity of zero?
An example of average velocity of zero is when an object moves in a full circle and returns to its starting point within a given time interval. Since the displacement is zero (starting and ending at the same point), the average velocity is also zero.
How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?
This scenario is possible if the car travels a certain distance in one direction and then returns to its starting point, resulting in an average velocity of zero. The average speed of 65 mph would be calculated as the total distance traveled divided by the total time taken, without considering the direction of motion.
Which describes average velocity of a uniclycle going around in circles?
The average velocity of a unicycle going around in circles is zero because it returns to its starting point over a full revolution, resulting in no overall displacement. However, the unicycle's speed may vary as it accelerates and decelerates during each rotation.
Can average velocity of a moving body can be zero?
It actually can. Say a car moves north at 50 miles per hour for 4 hours. Then it moves south at 50 miles per hour for 4 hours. In the end, it returns to it's starting point. The average velocity over that 8 hour period is then zero, because it really went nowhere.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
When A child throws a ball up in the air to a height of 3.5 m and catches it at the same point from which he threw it. The ball is in the air for a total of 1.7 seconds. What is the average velocity?
The average velocity of the ball is 0 m/s because it returns to its original position after 1.7 seconds. Since the displacement is zero, the average velocity is also zero.
How do you calculate market return in Excel?
For calculating the market return, the average daily returns of S&P 500 or Nasdaq or any other Index (that represents a 'market') over the last few years (say 5 years) can be computed. These daily returns are then annualized (average daily return * 365). In Excel, you can download the daily closing prices of the index. Calculate daily returns of the Index using the formula (P1 / P0 - 1), (P2 / P1 - 1) and so on.... This will give you daily returns on the stock. Calculate the average of all the values (daily returns) obtained using "Average" function. Annualise the returns as (Average Daily Return * 365) You can get stock prices in Excel format with the spreadsheet in the related link. It automatically downloads historical prices from Yahoo Thanks Vikash
Can the average velocity of a moving body be zero. state example?
Yes, the average velocity of a moving body can be zero. For example, if an object moves to the right for a certain distance and then returns back to its original position in the same amount of time, the total displacement would be zero, resulting in an average velocity of zero.
