Air friction, or air drag, is an example of fluid friction. Unlike the standard model of surface friction, such friction forces are velocity dependent. The velocity dependence may be very complicated, and only special cases can be treated analytically.
But compared to air resistance, friction plays a bigger role in most physics problems and the equation for friction is much easier to work with. In this lesson we'll learn about three different types of friction: static friction, kinetic friction and rolling friction.
The purpose of this lab is to construct a relationship between frictional forces and the normal force on an object, to calculate the kinetic and static coe cients of friction for various objects and surfaces and to ultimately gain a solid understanding of static vs kinetic friction.
List the various types of friction. Calculate the magnitude of static and kinetic friction, and use these in problems involving Newton’s laws of motion. When a body is in motion, it has resistance because the body interacts with its surroundings. This resistance is a force of friction.
What is the value of the coefficients of static and sliding friction between two surfaces? Purpose: To use methods of graphical analysis to determine the coefficients of static and kinetic friction between two surfaces. A complete lab write‐up includes a Title, a Purpose, a
Blast a car out of a cannon, and challenge yourself to hit a target! Learn about projectile motion by firing various objects. Set parameters such as angle, initial speed, and mass. Explore vector representations, and add air resistance to investigate the factors that influence drag.
What is the equation for the force air resistance, also known as the drag force? We can see that the drag force depends on 4 things (4 variables). Let's take a look at each one.
