The lab five B was about friction and how its always present. The purpose of this lab wat to explore how friction affect motion. There are three types of friction we discuss like air, rolling, and siding.

The two types of friction of the mousetrap car are rolling friction and static friction are the two types of friction that may affect the performance of the mousetrap car. The problem of the friction did I encounter and how do you solve them one types of friction i encounter was the static friction I had to take off some glue from the stick that had my wheels and to open eye screws. The factor did take into account to decide the number of wheels you decide to chose for the mousetrap car I saw a video of a car that had 4 wheels and it ran really fast, so I thought a 4 wheeled car would run fast or at least the four meters. What kind of wheels did I use in each axles I use tires as my wheels on each axles. I think the affects on using big wheels

5. Record the effort force shown on the Newton Scale in newtons while pulling the cart up the inclined plane.

First, we will set up the force table. The table comes in three separate pieces the base, stand and table once we connect and fasten all three parts we must use a circular level to make sure the table is balanced. If the force table isn’t balanced then we must adjust the base’s feet to the appropriate levels on each leg till the bubble on the level is centered. We must then assign where the positive & negative x, y axis are on the force table as a point of reference and label them with tape .Then for part I we must apply 1.96 N in the positive x – direction, and 2.94 N in the positive y-direction then we must balance the two with a third force and record the magnitude and direction of it and a draw a diagram showing all three forces. Part II

where F is force (5N) , m is mass (5kg), and a is acceleration (you have to find acceleration)

To test Newton’s seconds law if whether changing the mass or the force affects the acceleration of an object or a trolley in this case to increase or decrease.

The purpose of this lab is to calibrate two force sensors properly. Observe the directional relationship between force pairs. Observe the time variation of force pairs. We need to explain Newton’s third law in simple language.

The further the muscle is stretched the bigger the force it exerts. This is a linear effect.

Friction is the force that opposes the force applied on an object, as well as the motion of the object. The two types of friction covered in this lab are kinetic and static, but there are other types as well. Static friction ƒs opposes motion so that things do not move in relation to each other. Kinetic friction ƒk is the friction when objects are already moving in relation to each other. Examples of static friction and kinetic friction are riding a bike and moving furniture across the floor, respectively. It is important to note that friction is not dependent on the size of the area of contact between two surfaces assuming uniform surfaces. It is known that as the block pushes on the table, the table pushes back. This force is known as the normal force (ƒN) which is the equal force perpendicular to the object. In this experiment, it is noted that the table and room are stationary objects, and thus have no acceleration on them. This means that when the block is also stationary, the net force on the block is zero.

1. Why does the force begin to decrease with time? Note that a decrease in force indicates muscle fatigue.

Problem: How does the increase mass affect acceleration and the force of the accelerating object?

Explanation: This all happens because of the formula, Force = Mass X Acceleration. So physically when extra mass is added, the force will increase (e.g. 20 N = 2/m^2 x 10 Kg > 10 N = 2/m^2 x 5 Kg)

The objective of this experiment is to demonstrate the bending of a bean when loaded at the center of its length and examine its deflection when positioned in two different ways, when the flat side of the beam is support and when the thin side is supported. In addition, try to find linear relationship between the load applied and the deflection of the beam and comparing the experimental deflection with the theoretical deflection.

The benefit that machine provides is called a mechanical advantage. Its amount is defined by actual mechanical advantage (AMA, includes force of friction). There is also an ideal mechanical advantage (IMA) but it does not take in account the force of friction which is inevitable in our world.
