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.
You can calculate average speed by dividing the total distance travelled by the total time of travel. To go from speed to velocity, you would also need to determine the vector (direction of travel).
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.
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
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.
No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time).
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 term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
