Question
If you drop a ball it will fall 5 m in the first second of fall. If you instead toss it sideways, in 1 second it wil fall beneath its straight-line path a vertical distance of: less than 5 m.; 5 m.; more than 5 m.; none of the above.
When no air resistance acts on a nicely tossed basketball, its acceleration in midair is: zero; a combination of horizontal and vertical motions; upward in direction; downward.
The magnitude of G indicates that gravtiy is: a relatively weak force; a relatively strong force; responsible for the orbiting of planet; responsible for all falling objects.
Explanation / Answer
Part A) If the ball is tossed sideways it would have the horiontal velocity but its vertical velocity would be zero,which is similar to the first case if we consider the motion in vertical direction ,so the time taken would be same and distance covered vertical would be 5 m
Part B)Acceleration in mid air would be downwards and we generally write it a=-g where g is the acceleration due to gravity which always acts towards.
Part C) We know that F=GmM/r2 so force of attraction is dependent on G which is a constant,MAgnitute of G helps the planets to orbit as this force is balanced by the centrpetal force.
Acceleration due to gravity g is resposible for falling object not the G gravitional constant.
