When you hold a glass, you keep it from falling using the friction between your hand and the glass. How does friction prevent the glass from falling?

• The friction of the glass is smooth.

• Your fingers and the glass stick together.

• The friction acts upwards, opposing the downward pull of gravity.

• The friction acts downwards, opposing the upward pull of gravity.
