Question & Answer
Choose the Best Answer
The coefficient of friction will determine how quickly the ball stops bouncing.
Friction will have no effect on the ball's bounce height.
Friction will cause the ball to bounce higher on concrete than on grass.
The friction between the ball and concrete will always be zero.
Understanding the Answer
Let's break down why this is correct
The coefficient of friction tells the ball how fast it loses energy when it hits the ground. Other options are incorrect because Many think friction is unrelated to bounce height, but friction does change the ball’s motion; Some imagine concrete gives more bounce than grass because it is hard.

Definition
Friction in Physics refers to the force that opposes motion between two surfaces in contact. It plays a crucial role in determining how objects move on surfaces and is influenced by the normal force and the friction coefficient. Understanding friction is essential for analyzing the behavior of objects on horizontal and inclined surfaces.
