I think it is cuz speed is velocity it's just a vector (more difficult name)

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.
If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
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.
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.
Total distance divided by total time?
total velocity * * * * * It is the average speed, not velocity which is a vector.
Is numerical ratio of average velocity to average speed always equal?
No, the numerical ratio of average velocity to average speed is not always equal. Average velocity is a vector quantity that includes both magnitude and direction, while average speed is a scalar quantity that only considers magnitude. The ratio will be equal only when the object moves in a straight line.
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.
When is speed equal to the magnitude of velocity?
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
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.
Is distance the magnitude for average velocity?
No. Average speed is.
Is numerical ratio of average velocity and average speed is always less than one?
No, the numerical ratio of average velocity and average speed can be equal to or greater than one. This depends on the direction of motion relative to the distance traveled by the object. For example, if an object moves in the opposite direction to its initial position, the average velocity can be greater than the average speed.
What measurements of velocity and acceleration have in common?
TIME is a factor in both measurements. Velocity is speed (distance divided by TIME) in a given direction. Acceleration is measured in velocity per unit of TIME. Therefore, they both have TIME in common.
What do measurements of velocity and acceleration have in common?
TIME is a factor in both measurements. Velocity is speed (distance divided by TIME) in a given direction. Acceleration is measured in velocity per unit of TIME. Therefore, they both have TIME in common.
If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
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.
