A tennis ball is hit by a large force so that it goes up into the air and then it comes back straight down because of gravity.
<h3>How object move upward and downward?</h3>
We know that objects move upward due to application of force on it while on the other hand, object comes to the ground because of the attraction of earth which we called gravity.
So we can conclude that a tennis ball is hit by a large force so that it goes up into the air and then it comes back straight down because of gravity.
