Balance Balance is a state of steadiness in which all of the forces acting on the body are even, causing the center of mass to be within the base of support. Balance is maintained through a complicated interaction of several systems. These systems include the sensory system, the motor system, and the CNS. The sensory system is responsible for detecting body position and movement, while the motor system organizes and carries out movements, and the CNS integrates and plans our actions (O’Sullivan et

EXPERIMENT 201: WORK, ENERGY AND POWER John Michael A. Ramos, Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

PHY 1191 Lab X: Relative Motion Fall 2016 Objectives: To understand how relative motion is interpreted. To learn how to use vector addition to solve for relative velocities. Materials: Motion detector A fan A wind up car Background: Relative motion is when the motion of an object is being compared to some other moving object or reference point. These velocities can be calculated using vector addition, in the form of: Vac = Vab + Vbc Where the velocity of A with respect to

rotational, total, and static equilibrium. Understanding equilibrium and its varying forms lead to the understanding of how force and torque play an important role in not only establishing equilibrium but physics as a whole. Relevant Theory: A body at rest or moving with a constant velocity along a straight line is in equilibrium. Translational equilibrium exists when the sum of the forces acting on the body are zero; while, rotational equilibrium exists when the sums of the torques acting on the body are

acceleration is decreased (Newton’s 1). But since the frictionless cart is released on a declined ramp, the acceleration is increased due to the downward force of gravity on the cart (Holzner 1). Introduction The purpose of this lab is to prove and explore Newton’s Second Law of Motion, which states that acceleration is dependent upon two variables: the net force acting on the tested object as well as the mass of the object itself (Newton’s 1). The mass is known before completing the experiment, and the acceleration

Step 1-control: try to predict where the ball is going (your mind controls your motions, so if your mind is aimed at the ball, so is your body). Step 2-position: Place both hands out in front of you (including the one in the mitt) with your thumbs facing up. This way, if the ball bounces out of your glove, your other hand is there to catch it. However, if the ball is above waist level, you want your thumbs down in order to prevent injury. Otherwise, you could jam or brake a finger. While you are

My egg drop container is based off of a rough interpretation of the Apollo 17. My container demonstrates all the required topics of motion, energy and force. My egg drop container involves thermal, sound and mechanical energy. The container has mechanical energy, because it has both kinetic and potential energy. Prior to dropping the egg, the experiment has potential energy and as it’s drops, it has kinetic energy. The higher the drop point, the more potential and kinetic energy it has. When the

energy, force, gravity, inertia, Newton’s Laws of Motion, Velocity and weight that has to come together in order for a roller coaster to move. Roller Coasters are made by rapid changes in speed and or direction. The speed and direction of the riders change because the amount of acceleration the rides have. Two most important things that are needed in order for a roller coaster are kinetic energy and potential energy. A roller coaster ride has energy that is being transformed from potential

Henry Allen #1 Ms. Yuhas Due March 8, 2018 Science Introduction Every experiment is a combination of many things. The smallest change of one part might result in a different outcome. This project shows how force is used to start a chain reaction. It will demonstrate how marbles can exchange energy through magnets. By varying the number of marbles between the magnets, the speed of the last marble may increase or decrease. Magnets A magnet is a piece of iron that is attracted to other objects with

Isaac Newton formally published his three immortal Laws of Motion into one of his greatest works. The third and shortest of these scientific marvels states that every action force has an equal and opposite reaction force, which is true not only in science, but in life, where we can barely detect certain hypothetical reaction forces. An exemplary instance of this is when parents educate their children, then children educate their parents in return, a barely detected “reaction”. The power of children is
