Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change

How to Excel in Your Physics Course Most students realize that putting off studying until the day before the exam and then cramming at the last minute is not efficient. Some students do this anyway‚ because so far they have gotten away with it. Perhaps most of the other students you previously competed with had poor study skills. This may have allowed you to adopt poor or non-existent study habits and still keep up‚ or even get good grades if you are naturally a better student. Now that you

A car moving at a velocity of 25 m/s‚ accelerates at a rate of 6 m/s2. Find its velocity after 3s. 2. An object is dropped from rest. Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla Roadster car accelerates from rest

Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but
