Pre-Lab Questions
1.This lab contains two different experiments that cover two different aspects of friction. In your own words, describe both concepts and how each experiment demonstrates them.
The two different aspects of friction are static and kinetic friction. Static Friction is the force that
is put on an object to return to rest after it has been moved from an initial position. Certain heavy objects have enough mass to where the friction of the object keeps it in place, not even lifting or pushing by hand is not enough to move the object because the friction is greater than the force that is being pushed against it. Kinetic Friction is when an object is moved and has to work through the friction as the object is moving across the different surface layers. An incline plane can actually change the static friction of an object this is because the higher the incline the more likely the static friction cannot keep the object from sliding off. The mass of the object can also tell us how much incline the object can manage. Otherwise; Kinetic Friction will occur and slide against the incline this is because of the Kinetic Friction
2.The normal force plays an important role when studying friction. Describe the relationship between friction and the normal force.
The relationship between friction and the normal force is important in order to understand the frictional forces. Frictional force is calculated by the product of the coefficient of friction (it can be static or kinetic) and the normal force put on by a surface on an object. It is represented as Ffriction=μ⋅N
EXPERIMENT 1: STATIC FRICTION AND MASS ON AN INCLINE PLANE
Introduction Questions
1.Explain, generally, what you will do for Experiment 1.
I will be using the incline plane and then I will place different objects on top of it to watch the normal force, and then calculate the coefficient of static friction, as well as the kinetic friction
2.If the normal force only acts perpendicular to a surface, what happens to the magnitude of the normal force on an object as the angle of the incline is increased?
As the angle of the incline increases the force of the object will then decrease. Lab 4 Friction PHY250L
