How does the surface texture of a basketball court affect the game?

• It changes the color of the ball

• It affects the bounce and grip of the ball

• It makes the ball heavier

• It has no effect

What is the role of air pressure inside a basketball?

• To make the ball heavier

• To maintain the ball's shape and bounce

• To change the ball's color

• To increase the ball's size

Why is it easier to push a wheelchair on a smooth surface compared to a rough one?

• Less friction on smooth surfaces
