Physics lab measure acceleration on incline plane

Your point about pushing someone is a nice solid-body thought-experiment: You push Steve rightwards and the box car moves leftwards until he stops himself or the wall does and the force he uses to stop himself stops the boxcar.

For an example of an 'Open' EEI task sheet, click here. Photovoltaic power generation employs solar panels comprising a number of cells containing a photovoltaic material. The Australian Government provides incentives for the use of PVs for both domestic and industrial use you can save money, and save the environment.

Solar photovoltaics generates electricity in more than countries and, while yet comprising a tiny fraction of the GW total global power-generating capacity from all sources, is the fastest growing power-generation technology in the world.

Between andgrid-connected PV capacity increased at an annual average rate of 60 percent, to some 21 GW. A good EEI would be to measure current as a function of the angle of incidence of sunlight all within a short period of time eg 30 minutes ; measure current when collector is perpendicular to rays during the day how should that go?

But maybe you'll need to consider more than current; perhaps the power output is more important.

Where Physics Can Be Seen Everywhere

If so, you could put a load on the circuit resistor and measure V and I. In the method shown below, Moreton Bay College students are measuring the effect of angle on the flow rate hence power output of a electrical water pump.

This was Year Energy output of a solar panel II You could also investigate the effect of shade on the output of a panel. In this photo, students are using layers 1, 2, 3 etc of shade cloth.

It would also be interesting to see the effect of light of different wavelength to see if the solar cells are sensitive to all wavelengths. You could use coloured cellophane - but then that reduces intensity and not all coloured cellophane has the same percentage transmission.

This limitation makes photovoltaic cells an unreliable source of power for unattended or remote devices, such as solar-powered traffic signs or NASA's Mars Rover. For large-scale solar plants to maintain their maximum efficiency, the photovoltaic cells must be kept clean, which can be a challenging task in dusty environments.

One good EEI would be to investigate the effect of dust on the solar panel. This is a harder EEI than the two above.

It involves setting up a solar panel a short distance from an incandescent bulb eg 15 cm and adding controlled amounts of "dust" eg bentonite clay powder, fine sand, icing sugar to the face of the panel spread evenly.

It is a good idea to adjust the panel so it is working at maximum power. Do this by setting up the circuit on the left below, using either a variable resistor or fixed resistors that can be varied from 0 ohm to ohm. Plot a graph next figure to see the maximum power point. Then add the bentonite 0.

A good article is in Physics Education, V45, Septemberpage Solar panel output and temperature The output of a solar photo-voltaic PV panel changes during the day for two reasons: Here's what one user Cabel said on the Whirlpool Forum:Measure the acceleration of the disk as it rolls down the incline.

Just for fun, try both a big and a small disk to see if they give the same (or about the same) acceleration.

That's it. Oct 24,  · Homework Help: Lab Report Help Oct 24, #1. The purpose and objective of this lab is to obtain g, acceleration due to gravity, by using an inclined plane, and other materials, and to calculate g using the results. Motion Sensor – used to measure the acceleration of the Pasco car Computer – used for the software.

When an object sits on a frictionless incline plane, the two forces acting on the object are the gravitational pull of the earth, its weight, mg, and the supporting force supplied by the surface of the incline, the normal,.. These forces are shown in blue.

In the first three units of The Physics Classroom, we utilized Newton's laws to analyze the motion of objects. Force and mass information were used to determine the acceleration of an object. Acceleration Lab Teacher’s Guide and velocity vs.

time to find acceleration of a toy car. 2.

Inertia and Mass

Observe the relationship between the angle of an inclined plane and the acceleration of a toy car on the inclined plane. and raise it even more to get enough horizontal distance to measure deceleration. Table 4 Time (s) Position (cm) Position.
