What is the numerical ratio of average velocity to average speed when it is moving along a straight path?
The numerical ratio of the average velocity and the average speed for an object moving along a straight path is 1:1.
What is the numerical ratio of velocity to speed of an object a always equal to one B always less than one C always greater than one D either less than or equal to one?
Answer:The ratio is 1:1 because the distance travelled will be equal to magnitude of displacement.
What is the numerical ratio of average velocity to average speed of an object when it is moving along a straight path Class 9?
When an object is moving along a straight path, magnitude of average velocity is equal to the average speed. Therefore, numerical ratio of average velocity to average speed is one.
What is the ratio of average velocity and average speed?
∴Average velocityAverage speed≤1.
How is average velocity calculated?
Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. ¯v = average velocity. v = final velocity.
What should be the ratio of velocity is to speed for a moving object?
one
The displacement of the body in given time is always equal to or less than distance covered, because, velocity is displacement per unit time and speed is distance covered per unit time, therefore, ratio of magnitude of velocity and speed is always equal to or less than one.
Is the numerical ratio of speed to velocity equal to one?
Numerical value of velocity is always equal to the speed, hence numerical ratio of speed to velocity always equal to unity i.e., 1.
In which condition the numerical value of average velocity is equal to average speed?
Answer: The magnitude of the average velocity of an object is equal to its average speed, only in one condition when an object is moving in a straight line. The average speed is the total distance travelled in a given time frame and velocity is the total displacement in the time frame.
Is it possible that the average velocity of a particle is zero when its average speed is not zero?
Yes . The average velocity depends on the net displacement of a body so if a body starts from a position and comes back to same position after some time , the net displacement is zero . Consequently , average velocity is zero . While the speed depends on the actual path length covered .
Why average speed is not average of speeds?
Because the average speed is the total distance traveled divided by the total time elapsed. If you travel the same distance at each speed, you spend more time at the slower speed, so the slower speed ““counts more” in computing the average.
Is the numerical ratio of speed to velocity of the toy car equal to one explain?
Yes, A is the correct answer because velocity depends on displacement and speed depends on distance. 2nd case, If Displacement is equal to the distance in that case, as Displacement and Distance will be same the ratio will be equal to 1 because the time interval is same.
What is the difference between average velocity and average speed?
To understand this, we define average velocity and average speed. Average velocity is the ratio of total displacement to total time. Its direction is the same as the direction of the moving object.
How do you find the average speed of an object?
When an object is moving along a straight path or straight line, it means that its distance is equal to its displacement. So, Speed = Distance/Time & Velocity= Displacement/Time. Clearly, Speed=Velocity. Hence, Average Speed = Average Velocity in this scenario.
What is the difference between average speed and instantaneous speed?
Specifically, instantaneous speed is the magnitude of the instantaneous velocity vector. When moving along a straight path the velocity vector is always orientated in the same direction, and hence the magnitude of the average velocity is equal to the average speed.
How do you find the average velocity of a particle?
The average velocity of a body in a certain time interval is given as the displacement of the body in that time interval divided by time. So if a particle covers a certain displacement \\overrightarrow {AB} in a time t_1 to t_2, then the average velocity of the particle is:
