an object is thrown straight up and air resistance is negligible, then its speed when it returns to the starting point is the same as when it was released. If air resistance were not negligible, how would its speed upon return compare with its initial speed? How would the maximum height to which it rises be affected?
Step-by-step solution Step 1 of 3 Air resistance is the drag or resistance produced by the molecules air which comes in contact with object. Due to air resistance the objects slow down. Step 2 of 3 When an object is thrown straight up and air resistance is not negligible, the kinetic energy of the object does not totally converted into potential energy and vice versa. A part of energy of the object goes to counter the resistance created by the molecules of the air. So, while going up the speeds decreases faster as compare to the decrease in the speed without air resistance, therefore the maximum height is lesser as compare to the maximum height when there is no air resistance.
