How does increasing the number of data points on a position-time graph improve your ability to estimate instantaneous velocity at any point on the curve?

more data points give you a much closer estimate to the slope of the graph at one single point.
The slope of the graph between two points is the average velocity between two points, but with more points present, the data points will be closer together to give you a much closer approximation of the slope at one single point

The velocity of a car changes from 60 meters per second north to 45 meters per second north in 5.0 seconds The magnitude of the car's acceleration is?
a=change over velocity/time 60-initial velocity 45-final velocity 45-60= 15m/s 15/5= 3- acceleration
Why is pelton wheel not suitable for low heads?
low head will generate low velocity (since velocity is the function of head) which results into the less discharge. therefore the power generated will be less hence is not suitable
A car starts at rest and attains a velocity of 15 meters per second in 5 seconds what is its acceleration?
The average acceleration is given by the expression a ∆v/∆t (15 m/s)/5s 3m/s2 where a is acceleration, v is velocity, and t is time. ∆ (final-initial) value.
If you sit on a moving bus and toss a coin straight up into the air where will it land?
The coin is traveling at the same velocity as the tosser, so it will land the same as if you were standing still.
What is scalar data type?
Scalar data is the opposite of vector data, in that it provides a magnitude without a direction. For example, speed is a scalar quantity because it provides magnitude without a direction, whereas velocity is a vector quantity because it provides the magnitude that speed provides, but supplies us with direction.
What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
What is the Instantaneous velocity?
Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
Is instantaneous velocity a vector or a scalar?
Velocity is always a scalar, instantaneous or average doesn't matter.
Does the slope of a position time graph represent average velocity or rate of change of velocity?
The tangent at a point on the position-time graph represents the instantaneous velocity. 1. The tangent is the instantaneous slope. 2. Rather than "average" velocity, the slope gives you "instantaneous" velocity. The average of the instantaneous gives you average velocity.
When is the instantaneous velocity equal to avg velocity?
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
You want correct formula for instantaneous velocity?
v(t) = dsdt This should be the formula for instantaneous velocity.
What does instantaneous velocity mean?
Instantaneous velocity is a vector quantity representing the velocity Vi at any point.It is the time rate of change in displacement.
What is the relationship between average velocity and instantaneous velocity?
The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.
What is the difference between instantaneous velocity and instantaneous speed?
Speed, instantaneous or not, is a term used for how fast an object travels. Velocity, instantaneous or not, is a term used for how fast an object travels in a particular direction.
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.
