When one boy throws the ball to another boy, what type of friction happens
i don't understand it on my home work
no is it rolling sliding or fluid
fluid
When one boy throws the ball to another, the type of friction that occurs depends on the surfaces in contact and the conditions under which the throw takes place.
1. Static Friction: If the ball is stationary on the hand of the first boy before he throws it, static friction is present. Static friction is the force that opposes the motion of an object when it is at rest on a surface. It prevents the ball from slipping out of the boy's hand prematurely and helps accelerate it smoothly.
2. Kinetic Friction: Once the ball leaves the hand of the first boy and starts moving through the air, kinetic friction comes into play. Kinetic friction is the force that opposes the relative motion between two surfaces in contact when they are sliding past each other. Air resistance or drag acts on the ball as it moves, slowing it down gradually.
It's important to note that the friction between the ball and the air (kinetic friction) is generally much greater than any friction that might occur between the boys' hands and the ball (static friction).
To determine the exact nature and magnitude of the friction forces in a given situation, various factors such as the surface properties, the speed and angle of the throw, and air conditions would need to be considered.
