Why can you only calculate a stone's average speed during its fall?
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.
Does average velocity and average speed have the same number?
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.
Jake and Brenda drove at a speed of 30 mph for 1 hour. Then they turned around and drove 45 mph until they were back where they started. What is true about their average speed and average velocity?
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
Are average speed and average velocity always the same measurements why?
I think it is cuz speed is velocity it's just a vector (more difficult name)
What is the acceleration in science if you know average speed and time?
If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.
Why can you only calculate a stone's average speed during its fall?
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.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
Does average velocity and average speed have the same number?
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.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
How do you find the average speed from a velocity time graph?
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.
If skylar throws the football 50 meters in 3 seconds what is the average speed (velocity) of the football?
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.
Is the total distance divided by the total time?
Yes, to calculate the average speed, you divide the total distance traveled by the total time taken to cover that distance. This gives you the average speed for the entire journey.
In what condition average velocity is equal to average speed give an example?
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.
What is the formula used to calculate the velocity of an object?
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.
How can you get average velocity?
Average velocity is calculated by dividing the total displacement by the total time taken. It gives the overall velocity over a period of time, taking into account both the magnitude and direction of the motion. Mathematically, the formula for average velocity is: average velocity = (final position - initial position) / total time.
Why do you need to calculate velocity instead of speed?
Velocity includes both speed and direction, whereas speed only gives you the rate at which an object is moving. Calculating velocity allows you to understand how fast an object is moving and in which direction it is moving. It is essential for analyzing motion in physics and engineering applications.
Jake and Brenda drove at a speed of 30 mph for 1 hour Then they turned around and drove 45 mph until they were back where they started What is true about their average speed and average velocity?
their average speed is greater than their average velocity.
