Force in effect when car brakes A car of mass m=1200 keg is traveling at a speed of km/h. Suddenly the brakes are applied and the car is brought to a stop over a distance of mm. Assuming constant breaking force find: (1) the magnitude of the breaking force, (2) the time required to stop….

Purpose: To determine the period and the frequency of a ticker timer. Materials/Apparatus: One ticker timer One 1. 5+ meter tape One stop-watch Theory: One carbon paper disc One test tape The recording timer is a device that helps you study motion, it is a simple electric device plugged into mains power, with a stylus…

Image Formation by Lenses Objective: The objective of this lab is to create different images by using the converging and diverging lenses as both lenses project light. Introduction: A key formula when working with lenses is the Thin-Lens Equation: Where f is the focal length of the lens, do is the object distance and did…

Strictly speaking, will a penny be slightly more massive if it has a negative charge or a positive charge? Explain. A negative charge because when it is negatively charged electrons are added to the penny. 17. What is the voltage at the location of a 0. 0001 C charge that has an electric potential energy…

I. E. Is a part of natural philosophy and a natural science that involves the study of matter[6] and its motion through space and time, along with related concepts such as energy and force. [7] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [8][9][10] Physics…

The two objects of equal masses are suspended over a light pulley, the objects will move only until they are both at equal distances from the ground. Then they will not move at all. 2. Net force, mass of an object, and acceleration. 3. (A) Acceleration would increase. The mass of one side is greater…

An Investigation to determine how a change in mass can affect the traveling distance of a plastic tub. Aim: To investigate weight variation of a plastic tub and how it affects it’s traveling distance when propelled with a constant force using an elastic band. Hypothesis: The tub will travel less distance when the weight of…

Two 25. 0-N weights are suspended at opposite ends of a rope that passes over a light, frictionless pulley. The pulley is attached to a chain that goes to the ceiling. A. What is the tension in the rope? B. What is the tension in the chain? 2. A stockroom worker pushes a box with…

It is also the product of angular velocity. It is made up of the sum of the angular momentum of the body’s segments. The variables that influence angular momentum are the rotational speed of the gymnast, point/center of rotation, and the configuration of the gymnast’s body. For a gymnast of a given mass, how that…

Conduction, Convection, and Radiation The three types of heat transfers are Conduction, Convection, and Radiation. Heat always moves from a warmer place to a cooler place. For example hot objects that are in a room that is cooler than the temperature of the object will eventually cool to room temperature. First is conduction, conduction is…
