Specifically, gravity increases a falling object's velocity by 9.8 meters per second (m/s) with every passing second.
#Freefall position function in meters free
In free fall, gravity constantly accelerates an object (increases its velocity)-until it hits terminal velocity. You wouldn't want to try that on your bicycle!
The steepest "hill" you could imagine is not much like a hill at all, but rather a sheer vertical drop-where objects go into free fall and where gravity gives the biggest push of all. Finally, you know that the steeper the hill, the faster you go. The longer you feel that push from gravity, the faster it makes you go. You also know from experience that the longer the hill, the faster you go. Gravity is giving you an extra push, so you don't have to do all the work with the pedals. You know from experience that when you ride a bike downhill, it is easy to get going fast. But how does this affect how quickly something falls and its impact? For example, did the object move faster right after leaving your hand, or just before hitting the ground? In this science activity, you will explore the relation between time and distance traveled when a moving object is under gravity's constant acceleration. Have you ever dropped something and wondered how fast it was moving while falling? (If it was something fragile, you might not have been thinking about this at the time-you were likely too busy trying to grab the object!) We all know that gravity forces an object to fall.
