what is the velocity value at a sensor depth of 0.3 m on the tape measure
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and acceleration.
Velocity is a vector quantity, which means it is made up of more than one numeric value. Velocity vectors must contain information on speed and direction.
Acceleration means how fast the body's velocity changes - in symbols, dv/dt. Average acceleration during a certain time is equal to (change in velocity) / (time elapsed). Since you are dividing a velocity by a time, the standard unit for acceleration is (meters / second) / second, but this is normally written as meters / second squared.
No. accuracy is a measure of how close the measurements are to the true value.
No units - it's a percent value.
The dependent value on a velocity-time graph is velocity.
the approximate value of orbital velocity is about 8km/hr.
Velocity is an instantaneous measure. Mathematically, it is the limiting value of the change in the position vector divided by the change in time as the latter tends to zero. Over larger time periods, the average velocity is the total change in the position vector divided by the total change in time. If velocity is constant, the average velocity will be the same as the instantaneous velocity.
Only if the velocity is constant.
This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
Velocity = Displacement/Time =10.55m/11.31s = 0.932m/s Value of constant velocity is 0.932m/s.
For the instantaneous value of average velocity, average speed and average velocity are equal.
Velocity = distance / time
No, you've got it backwards. The absolute value of velocity equals speed. Velocity is speed with a direction; speed is just a number, without regard to direction.
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
