sharon sprinter changes her speed from 4.5m/s to 7.5m/s in the middle 1.5 seconds of a 100m race. what is her average velocity for this time period?
That is just not true! If you can calculate its average speed you should be able to calculate its speed at any point in time during its flight, including its final velocity.
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
I think it is cuz speed is velocity it's just a vector (more difficult name)
total velocity * * * * * It is the average speed, not velocity which is a vector.
That is just not true! If you can calculate its average speed you should be able to calculate its speed at any point in time during its flight, including its final velocity.
For the instantaneous value of average velocity, average speed and average velocity are equal.
Velocity is speed and its direction. Average velocity is average speed and its direction.
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
To find the average speed from a velocity-time graph, calculate the total distance traveled and divide it by the total time taken. This will give you the average speed. Alternatively, you can find the slope of the secant line that connects the initial and final points on the graph to determine the average speed.
The average speed is 16.66... (repeating) metres per second. It is not possible to calculate the average velocity without further information because, due to gravity, the velocity is changing continuously during the ball's flight.
Acceleration equals velocity divided by time i.e a=v/t The S.I unit of Acceleration is m/s2
When an object is moving along a straight line at a variable speed, we can express the magnitude of the rate of motion in terms of average velocity.It is the same way as we calculate average speed.
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
The formula to calculate the average angular velocity of an object in motion is: Average Angular Velocity (Change in Angle) / (Change in Time)
their average speed is greater than their average velocity.
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
