Forces Test Review 1. Inertia can be best described as the (A) force that keeps an object in motion with constant velocity (B) force that keeps an object at rest (C) force that overcomes friction (D) property responsible for an object's resistance to changes in motion (E) property responsible for slowing down an object 2. A box is given a sudden push up a ramp. Friction between the box and the ramp is not negligible. Which of the following diagrams best represents the directions of the actual forces acting on the box as it moves upward after the push?
The formula can be applied to calculate the force generated when you sit on a chair, however thanks to newton’s third law of motion this is also the force that the chair acts upon you and prevents you from falling though you chair. Without specifying the nature or origin of the forces on the two masses, Newton's 3rd law states that if they arise from
This is the force resisting motion between the elements making up a solid material while it undergoes deformation. One very important element when it comes to friction is kinetic energy, which is the energy that an object possesses dude to its motion. Kinetic energy is converted into heat whenever two surfaces in contact move relative to each other. Heat is the energy transferred from one system to another via thermal interaction. Friction is not a fundamental force and it occurs because of the electromagnetic forces between charged particles, which constitute the surfaces in contact.
The maximum frictional force that must be overcome before movement is able to begin is μsFN. If you apply a constant force to pull an object along a horizontal surface at a constant speed, then the frictional force opposing the motion is equal and opposite to the applied force, Fp. Therefore, Fp = Ff. The normal force is equal and opposite to the object’s weight when the object is on a horizontal surface and the applied force is horizontal. The question to be answered by performing this lab is how can the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
Newton’s Second Law Lab Purpose: The purpose of this experiment was to determine the relationships between mass, force and acceleration as well as to prove Newton’s second law Hypothesis: It was hypothesized that there would be an inverse relationship between acceleration and mass; as the value of the mass increased the acceleration decreased. As well it is hypothesized that there would be a direct relationship between the net force and acceleration; as the net force increases the acceleration increases as well. Materials & Method: The materials that were required to do the experiment were a metre stick; its purpose was to measure the amount of string that is going to be used to drag the cart. Next equipment needed for the lab was a dynamic cart; it was going to be dragged by the string with a mass on the other end and will find relationships between these two. Also string (about 75cm) was needed in this experiment which would help pull the cart with the help of the masses that were used.
Once the results are found you can calculate the percent error of the uncertainty values. The uncertainty value is the acceleration of the ball falling down. That value will be compared to the gravity value to see how closely related they are. Introduction The formal lab “Uniform Acceleration”, studies uniform acceleration by rolling a ball down a ramp and dropping an object to calculate its acceleration. Also this lab teaches about measurement uncertainty can be calculated using the percent error equation.
The position of two wings should be relative to each other as if they were very close then the resultant force will be in opposite direction and thus cancel each other. Two wings produce more down force as the lift coefficient increases and the drag decreases. Table 1. Calculated value of Air Resistance Determination of Air Resistance Air resistance is the resistance offered by air to the movement of a vehicle. The air resistance has an influence on the performance, ride and stability of the vehicle and depends upon the size and shape of the body of the vehicle, its speed and the wind velocity.
Fist name, last name Physics ### Lab: Rotational Equilibrium The purpose of this lab was to analyze the physical effects of torques on an object and all the factors that can influence the magnitude of its strength and force. In lecture, we learned that although the magnitude of the force can have a strong effect on the rotational velocity of an object, the location or displacement of that force can have an enormous impact on the force’s effectiveness to do work. In this experiment, we saw, first hand, how a small force can have as much of a dramatic impact on an object as a larger force if the displacement is right. The goal of this experiment was to balance a meter stick at its center of gravity using different weights on opposite ends of the stick. Making the left side our positive direction, and our right, the negative direction was essential in proving algebraically, the results of the experiment.

There are precise definitions of these words in the technical world. In this section we will learning more about strain, strain equation and different types of strain. There are basically two types of stress acting in nature Normal stress: It is a type of stress experienced when elastic restoring force or deforming force acts normal to the surface area. They are of two types - Tensile and compression stress. If there is an increase in the length or
