Mass

using torque to mass a meter stick – without using a triple beam balance or spring scale / force meter. Materials: One meter stick One fulcrum Three sliding Clips One 50 gram hanging mass Procedures: Setup fulcrum Attach a sliding clip at the 50 cm mark of the meter stick and place meter stick on a fulcrum. From that point, move the sliding clip left and right (based on which side of the meter stick is going down/up) until you are able to identify a precise value for the center of mass. If…

falling precipitously. While the average pellet shot has a mass of no more than a few ounces and a duck weighs on the order of several pounds, the impact from the shot is enough to significantly redirect the trajectory of the duck. This occurs because while the pellet is very light, it is moving at an incredibly high speed relative to the duck. All moving massive objects possess this property of momentum, a quantity proportional to the mass of the object times its velocity. Momentum is what…

1. C Why: according to Newton’s first law of motion, an object that is free from all outside forces travels at a constant velocity, covering equal distances in equal times along a straight-line path, C is true. 2. D Why: not matter an object is still or is in motion, the object has inertia all the time. Inertia is a nature/property of any objects. 3. D Why: the ship is moving at a constant speed, which is in a balanced status. For the athlete, it would be likely to do a long jump on ground.…

This chapter includes the design procedure for the vibration absorber system made up of SMA springs. The vibration absorber is consisting of a mass M on which we mounted a bracelet which is made up of four mass-spring-damper systems as shown in fig. two vertical and two horizontal. This system would follow the principles of inertia to counterbalance the forces of a tremor. Let’s assume, throughout a tremor the hand will moves in X and Y direction and also sometime it will rotate between X and Y…

detail. The dead spot, although not a sweet spot, is where, upon collision with a tennis ball, the effective mass of the racquet is equal to the mass of the tennis ball (Cross, Lindsey & Brody, n.d.). This comes from Newton’s second law, F = ma, which can be rearranged to m = F/a. When this happens, the ball loses all its momentum. Think of a collision between two balls of the same mass, one at rest. The ball at rest gains all the energy from the incident ball, leaving the incident…

Introduction: The purpose of this lab is to help students gain a better understanding of physical concepts such as work (which occurs when an applied force moves an object.) torque (defined as a twisting force), energy and rotational inertia (an object's resistance to rotation). Experimental Design: My group’s testable question throughout the mousetrap car experiment was: If we add and subtract factors such as material, weight and shape, from the wheels of our car, how will it affect the…

changed after we put the egg into warm water. The mass of the egg increased to 79.56 grams when it was left in warm water for 15 minutes. After the egg was left for 24 hours in warm water, the mass increased to 85.59 grams. When we put the egg into the corn syrup the next day and let it sit there for 15 minutes, the weight of the egg decreased to 80.94 grams. The mass of the egg drastically changed when it was left in the corn syrup for 24 hours. The mass of the egg went from 80.94 grams to…

the hanging mass to fall a known distance that can be determined experimentally? (as seen in Figure 1) Before beginning to attempt to answer the question, the lab had to be set up correctly. First, the rotating object was set tangent to the hanging mass. Once the hanging mass was released from rest, the rotating object began moving in the clockwise direction. The weights placed on the rotating object would also affect the time for the hanging mass to hit the floor.The greater the mass, the less…

Newton’s three laws of motion essay Isaac Newton was an English physicist, mathematician, astronomer, and natural philosopher who lived in the 17th century. One of his accomplishments was coming up with three laws of motion that can be used to explain how and why stuff move. These laws that Newton came up with are still used today. Newton’s first law of motion states that “an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it”.…

mb is the mass of the block and m added is the additional mass on the block. Procedure: weigh the block. Record this value as mb. 2. With the block on one of its broad sides, run the string over the pulley. Adjust the string to ensure that it is level. Attach the mass holder to the free end of the string. 3. Find the mass on the mass holder that will allow the block to slide at constant speed once it is set into motion. Record this value as fk. 4. Add enough mass to the mass holder…
