How do you find instantaneous speed of the body at certain point?
Venkateshsonnaitanka...
To obtain instantaneous speed you will need to utilize the formula v = speed multiplied by time if you have the speed already. If you do not have the speed use v = dx/dt.

Speed at a given point in time?
The speed at a specific point is relative to observation point and motion of the body and therefore it should be called slip speed.
A distance-time graph for a body starting from rest how will you determine the speed of a body from this graph?
The instantaneous slope at any point along the graphed line is the speed at that point in time.
What do you mean by instantaneous speed?
Instantaneous speed is the speed of a body at any one instant. There is really no such thing as the instantaneous speed, it is merely the average speed over a very short space of time.
Compare and contrast velocity and instantaneous speed?
velocity is just a general term for speed (it could be average velocity or instantaneous velocity). Instantaneous velocity/speed (same thing) is the speed at that second. If you are familiar with calculus, it is the derivative of the position graph. Whereas average velocity is how fast the object is going in, for example, 1 hour, it is the speed that is maintained the whole hour (or the average) Instantaneous would be that at the second, at for example t=1.425, the speed is 24m/h . something along those lines
What is the difference between insantaneous speend and average speed?
The instantaneous speed is the speed of a moving body at an instant. Average speed is the overall speed through a period of time. These are two important aspects of differentiation in calculus.
What is intantaeous speed?
If a body is moving at a non-constant speed then its instantaneous speed is the derivative of its displacement with respect to time.If the body is at positions x(t) and x(t+dt) at times t and t+dt then the instantaneous speed at time t is the limit, as dt tends to 0, of [x(t+dt) - x(t)]/t.In graph terms, it is the gradient of tangent to the displacement-time graph.
What is used to measure the speed of a moving body?
A commonly used device to measure the speed of a moving body is a speedometer. It measures the instantaneous speed of a vehicle by calculating the rotational speed of the wheels and converting it into a speed reading. Other methods such as radar guns or GPS devices can also be used to measure speed accurately.
Can the average speed of a body be zero and can the average velocity of a moving body be zero?
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
Why is the motion of a particle along a circular path with a uniform speed said to be an accelerated motion?
To accelerate a body one must change its velocity or direction at an instantaneous moment. Since in a the velocity is uniform the direction at every point on the circular path is different. Thus making it accelerated.
How can you obtain the average velocity and instantaneous velocity from a displacement -time graph?
You cannot because a displacement-time graph is concerned only with radial motion: displacement from a fixed point of reference. Any transverse motion is completely ignored. Thus, if you had a body going around in a circle about the point of reference, its speed would be recorded zero!

Can the average velocity of the body be the same as instantaneous velocity?
Yes, the average velocity of the body can be same as the instantaneous velocity at a small time interval.The values of the average and the instantaneous velocities approach each other , as the length of time interval is decreased.
