What does velocity divided by the time interval equal?
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
Can the average velocity of a body be the same as the instateneous velocity?
Yes, But in uniform motion only.
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.
Instantaneous speed at an instant is equal to magnitude of instantaneous velocity at that instant Why is it so?
Instantaneous velocity mean change of displacement in extremely small amount time. (in math way, taking[ lim t--->0 (change in displacements/change in time) ]. instantaneous speed is the same expect displacement change to distance. So,because of very very small change in time, magnitude of distance and displacement will be same for any direction the object is moving.
Does a speedmeter give instantaneous speed or velocity?
Velocity is a vector quantity, so a different direction makes a different velocity. Speed is a scalar quantity, where direction makes no difference. Since a speedometer reads the same regardless of direction of motion, it is providing speed, not velocity.
Can the average velocity of a body be the same as the instantaneous velocity?
Yes, but in uniform motion.
Would instantaneous velocity yield the same value as average velocity?
Instantaneous velocity and average velocity are not the same. Instantaneous velocity is the velocity at a specific moment in time, while average velocity is the total displacement over a given time interval. In general, they will not have the same value unless the motion is at a constant velocity.
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
What Is the difference between velocity and average velocity?
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.
Compare and contrast velocity and instantaneous speed?
Velocity is a vector quantity that includes both the speed of an object and its direction of motion. Instantaneous speed, on the other hand, is the magnitude of an object's velocity at a specific moment in time, without regard to direction. Velocity is more comprehensive, providing information on both speed and direction, while instantaneous speed is a specific measurement of speed at an exact instant.
When is the average velocity is equal to the instantaneous velocity?
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
Are instantaneous velocity and acceleration the same?
no.
What does velocity divided by the time interval equal?
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
Does the instantaneous speed ever equal the magnitude of its average velocity?
Yes, instantaneous speed can be equal to the magnitude of the average velocity when an object is moving in a straight line without changing its direction during the motion. This occurs at the moment when the instantaneous velocity vector is in the same direction as the average velocity vector.
When will the average acceleration be equal to instantaneous velocity?
The average acceleration will be equal to instantaneous velocity when an object is moving at a constant speed in a straight line. This occurs because the velocity remains constant, resulting in the average acceleration being the same as the instantaneous velocity.
When is instantaneous acceleration and average acceleration the same?
Instantaneous acceleration and average acceleration are the same when an object's acceleration is constant over the entire time interval being considered. This means that the object's velocity is changing at a constant rate, resulting in both the instantaneous and average accelerations being equal.
Can the average velocity of a body be the same as the instateneous velocity?
Yes, But in uniform motion only.
