When a body travels equal distance with speeds V1 and V2 the average speed v is the harmonic mean of two speeds?

When a body travels equal distance with speeds V1 and V2, the average speed (v) is the harmonic mean of two speeds. When an object is travelling with variable speed, then its speed at a given instant of time is called its instantaneous speed. It is a vector quantity, as it has both, the magnitude and direction.

When a body moves with speed V1 and V2 for an equal interval of time then its average speed is given by?

The average speed is equal to ( v1 • t+v2 • t) / 2t. Explanation: divide the motion into two parts.

How do you find the average speed when given two speeds and distances?

To get average speed, s , divide total distance by elapsed time: Dt. To get elapsed time, t , divide total distance by speed: Ds. To get distance, D , multiply speed times the amount of time: s × t.

When a body travels equal distance in equal interval of time the speed of the body is said to be?

Uniform motion
The type of motion in which the object travels with uniform speed is called Uniform motion. This means that the velocity of the body remains constant as it covers equal distances in equal intervals of time. In the case of uniform rectilinear motion, the acceleration of the body will be zero.

When a body travels equal distances in equal interval of time is called?

A body is said to be in uniform motion, if it travels equal distances in equal intervals of time.

When an object travels unequal distances in equal interval of time the motion is called?

Whenever and object covers unequal distances in equal interval of time, the motion is said to be non-uniform motion. In this case, the answer is uniform motion.

How do you calculate average speed and distance?

The formula can be rearranged in three ways:

1. speed = distance ÷ time.
2. distance = speed × time.
3. time = distance ÷ speed.

How do you find average speed with the same distance?

Average Speed Formula

1. Average speed = Total Distance covered/ Total Time Taken.
2. When the distance is constant: Average speed = 2xy/x+y; Where, x and y are the two speeds at which the same distance has been covered.

When a body covers equal distance in equal intervals of time .the speed of the body is a average speed B non uniform speed c uniform speed D all the above?

We know that when an object travels equal distances in equal intervals of time, it moves with uniform speed. This shows that the distance travelled by the object is directly proportional to time taken. Thus, for uniform speed, a graph of distance travelled against time is a straight line, as shown in Fig. 8.3.

When a body covers unequal distances in equal intervals of time it is said to be?

Answer: If a body covers unequal distance in equal intervals of time, the body is said to be in non-uniform motion.

How to calculate the average speed to cover three equal distances?

And the total distance covered by the body can be easily calculated as 3D. Hope the formula helps you to find out the results.!!! let t1 , t2 & t3 be the time took by speed v1 , v2 & v3 to cover three equal distance. This is the average speed to cover three equal distances.

How do you find the average speed of an object?

When a body travels equal distance with speeds V1 and V2, the average speed (v) is the harmonic mean of two speeds. 2 / v = 1 / v1 + 1 / v2 When an object is travelling with variable speed, then its speed at a given instant of time is called its instantaneous speed.

How do you find the average speed of a particle?

If particle travels with speeds v1, and v2 for equal time intervals, i.e., t1 = t2 = t3, then Average speed = v1 + v2 / 2 When a body travels equal distance with speeds V1 and V2, the average speed (v) is the harmonic mean of two speeds. 2 / v = 1 / v1 + 1 / v2

What is the difference between uniform speed and average speed?

If an object covers equal distances in equal intervals of time, then its speed is called uniform speed. If an object covers unequal distances in equal intervals of time, then its speed is called non- uniform or variable speed. The ratio of the total distance travelled by the object to the total time taken is called average speed of the object.
