In the Tumble Buggy Lab‚ my partners and I used several different methods to calculate the velocity of a Tumble Buggy. The methods we used were a meter stick and a timer‚ a Spark Timer‚ a Photogate‚ and a Motion Sensor. Each method was different but overall‚ our velocities were very similar. Using the meter stick and timer‚ our velocity was 0.22 m/s. With the spark timer‚ our velocity was 0.26 m/s. Next‚ the velocity found with the Photogate was 0.325 m/s. Finally‚ when we used the motion sensor

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total

have XL=XC and the impedance‚ Z is equal to the resistance R‚ where Z=R. Because the capacitative and inductive reactances vary with the frequency of the AC current‚ the impedance of a circuit containing capacitors and inductors also varies with AC frequency. For a circuit with AC current flowing at angular frequency ω‚ its impedance is given by where XL = ωL is the inductive reactance‚ XC = 1/ωC is the capacitative reactance‚ R is the resistance‚ and ω = 2π f ( f is the linear frequency).
