Question

You throw a ball. Air resistance on the ball is negligible. Which of the following functions change with time as the ball flies through the air?

1) Position
2) Velocity
3) Acceleration
4) All of the above

Answer 1

In projectile motion with negligible air resistance, the position, velocity, and acceleration of the ball change with time.

Step-by-step explanation:

In projectile motion with negligible air resistance, the position, velocity, and acceleration of the ball change with time.

The position of the ball changes because it moves in a parabolic path due to the gravitational force acting on it.

The velocity of the ball also changes because it continuously increases due to the acceleration caused by gravity.

Finally, the acceleration remains constant throughout the motion and is equal to the acceleration due to gravity.
