Jharkhand with coal production of 113.014 Million tons stand at 2nd in the list of top 10 largest coal producing states in India. Apart from being the leading coal producer, Jharkhand is also the state with highest coal reserves in India, which is 80,716 Million tons.
In free fall do all objects fall with the same acceleration? yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.
Specifically, gravity increases a falling object's velocity by 9.8 meters per second (m/s) with every passing second. (Whereas velocity is measured in m/s, acceleration is measured in meters per second squared, or m/s 2 .) How does this constant acceleration affect the distance that an object travels over time?In this experiment you will roll a marble down a ramp to find out. Mark the distance traveled on the ramp each time. 2  Using a longer ramp, how does gravity appear to affect the velocity and acceleration of a marble as it rolls downhill? 3  Extra: Try repeating this activity with different balls, such as a rubber ball, large metal ball bearing, ping pong ball, etc.
