‘A football player kicks a football to another player of his team who then kicks the football towards the goal of the opposite team. The goalkeeper there collects the football and kicks it towards a player of his own team’. The number of times the velocity of the ball changes is

4 times .

The football's velocity changes four times. It changes the first time when the first player kicks the ball to another player, setting the ball into motion. It changes the second time when the second player kicks the ball to the goalkeeper. The third time, its velocity changes when the goalkeeper makes a save. The fourth change is when the goalkeeper kicks the ball towards a member of his own team.
By Newton’s second law of motion, we know that a force is required to change the velocity of an object. The agent providing the force for change in velocity in each case is as follows:
In the first instance, it is the first player.
In the second instance, it is the second player.
In the third instance, it is Goalkeeper.
In the fourth instance, it is Goalkeeper.
