When the football is initially at rest and the player kicks it, the ball’s speed increases from zero as the force of the kick accelerates it in the direction of the kick.

Quick Scoop: What Happens to the Ball?

  • At the start, the football is at rest, so its speed is zero.
  • When the player kicks it, they exert a force on the ball with their foot.
  • This force causes the ball to accelerate, so its speed increases while the foot is in contact with it.
  • Immediately after the kick, the ball moves away with some positive speed depending on how hard it was kicked.
  • As it travels through the air and along the ground, friction and air resistance gradually slow it down.

So, answering the core question in simple terms:

If the football is initially at rest, its speed increases from zero as the player kicks it, becoming greater than zero while the force is applied, and then later decreases due to friction and air resistance.

Mini View: Physics Behind It

  • The kick provides an unbalanced force on the ball.
  • By Newton’s second law, this force causes acceleration, which is the rate of change of speed.
  • Therefore, while the kick is happening, the ball’s speed is increasing from rest.
