When an object and acceleration is zero at some instant t in time its velocity is?

You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.


Describe the motion of a satellite relative to the direction of gravity at any moment in time?

Derive acceleration relative to time and plot the resultant velocity (centripetal and tangential) as a vector.


How do you derive the formula for cetripital acceleration?

That is done via calculus. Specifically, take the movement over a small distance, calculate the change in velocity divided by the time, and figure out what happens if the time interval gets smaller and smaller - as they say in calculus, "get the limit of the acceleration as the time tends towards zero".

How you can derive the velocity unit?

velocity=distance / time


What information can be learned from a position-time graph and from a speed-time graph?

A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.


Derive the equation for instantaneous average acceleration vector?

You have a contradiction in your question. Instantaneous acceleration is the acceleration at a certain moment in time. Average acceleration is the average over a time interval.


What is the momentum and derive the formula for the momentum?

Momentum is the product of the mass and the velocity of an object. It's SI unit is kgms-1. Correct, but perhaps more easily interpreted as kgm/s.


How would you arrive at mathematical formula to measure force using 2nd law of motion?

Consider a body of mass m. It initially moves with velocity u and accelerates at a constant rate a. It attains a final velocity v after timet. This acceleration is caused by force F. Now, Newton's second law of motion can be mathematically represented asYou know that,Using this, we obtainF = ma = Mass � AccelerationThus, we can re-state Newton's second law of motion


Why is KE equal to half mass velocity squared?

You can derive it from accelerating an object to a certain speed. Assume constant acceleration (and therefore constant force), and calculate how much work (force x distance) you need to get the object to a specific speed.


How do you derive the formula of ozone layer?

Ozone layer has no formula. However there is a formula for ozone and that is O3.
