Dynamics track includes a plunger cart that has a spring-loaded plunger for consistent collisions while the included dynamics cart is similar but has no plunger. Track length of 1.2 meters is long enough for most dynamics experiments yet a convenient length for storage. Adjustable feet and ring-stand bracket make it easy to level or turn it into a ramp. Coated with a clear anodized finish, this track provides lower friction than bare metal. Scalars are represented symbolically with just the letter What is meant by drawing a vector to scale? Give numerical example length is arbitrary on graph paperĬhoose a convenient scale to be able to graph by increasing or decreasing ratios What is meant by resolving a vector into components? Give example vectors are drawn from the originĢ rectangular components Briefly describe the steps in the component method of vector addition vector R can be resolved into x and y components vector Rx and vector Ry.This dynamics track is the highest quality we’ve ever tested! Use this dynamics track with the included Vernier carts and obtain amazingly accurate results when studying the laws of motion. Vector quantity has both magnitude and directionĮx: velocity, displacement, acceleration, and force How are vectors represented graphically, and how are scalars and vector quantities distinguished when written as symbols? vectors represented graphically by arrows, symbolically with the letter and an arrow drawn over it. Scalar quantity is one with magnitude only Velocity and acceleration calculated How would the mass of the clip affect the experimentally determined value of g? gravity doesnt depend in mass, the clip does not affect the value of g Is air friction a systematic random or both types of error systematic What kind of error would fluctuations in the discharge timer intervals be? random What kind of error is the measurement of length to a fraction of a millimeter systematic and random Distinguish between scalar and vector quantities, and give examples. Terminal velocity Which quantities are measured and which ones are calculated in this experiment? distance between dots measured Object falls for few meters with 9.8 m/s then air resists and objects acceleration would be constant, weight = air resistance How would this affect the experimentally determined value of g? air resistance slows down the object ∆x= V₀t + ½at² In this experiment air resistance is negligible. T on x-axis What is the difference between average and instantaneous velocity instantaneous velocity is equal to the midpoint at the time intervalĪverage velocity is uniform acceleration Describe how the instantaneous velocity of an object in free fall can be calculated from displacement and time data slope Selective errors What is the equation describing the instantaneous velocity of an object in free fall? Vf=Vi + at What is the shape of the graph of the instantaneous velocity versus time? V on y-axis Gives vertical distance of fall What precautions should be taken in using this apparatus make sure it is vertical How would you experimentally determine if it was pure gold or not? measure density, displacement methodĬompare densities to that of pure gold and if the values dont match then there could be silver alloy present How are data recorded on the tape strip and what information does the data give? paper passes through discharge electrodes leaving a record of dots at certain time intervals Describe how you would experimentally determine its volume You should put a weight on the object and continue with water displacement procedures, making sure to measure the weight beforehand so it can be subtracted The king suspects that his crown is not made of pure gold. Suppose that you were given an irregularly shaped object that floats.
