Projectile motion using photogates

Projectile Motion (Photogates)

My teaching begin at a time when our schools had little in the way of technology, but a lot of energy and interest in doing lab activities. The dielectric is outlined as two rectangles in the image so you can see the edges.

Intermediate School Teacher, Bayview Middle School, Toronto District School Board As a science and technology teacher for over 10 years, I have learned that adapting to our new tech-savvy youth is essential if educators are to effectively engage students and student learning in the 21st century classroom.

Reposition the Photogates if necessary.

Zeeman Effect

Mark a point on the ramp to roll the ball from each time. It's a common method for measuring fluid velocity. It works by using the mechanical principle of leverage to propel a stone or other projectile much farther and more accurately than other catapults. They are used to store electric charge.

Then vary the length of the pipe, or its thickness, or the pressure, or the viscosity and so on. Secondly, knowledge of the electrical conductivity of meat may give important knowledge about electrical safety for humans. The battery or power supply used to charge the capacitor should not exceed its rated value eg 2.

This course is recommended for students in Grade 12 but may be taken by students in Grade Later named clepsydras "water thieves" by the Greeks, who began using them about BCE, these were stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom.

However, using something like nichrome should work OK. Change and constancy occur in Earth's system and can be observed, measured as patterns and cycles, and described or presented in models used to predict how Earth's system changes over time.

PASCO ME-8930 Instruction Manual

May need one drop of detergent why? The kinetic energy of the target is conserved as gravitational potential energy. Three of my Year 12 Physics girls Georgia, Shannon and Georgina at Moreton Bay College made up coils of copper wire on cotton-reels in an experiment about guitar pickups.

Students are expected to: A define and use the concept of a mole; B calculate the number of atoms or molecules in a sample of material using Avogadro's number; C calculate percent composition of compounds; D differentiate between empirical and molecular formulas; E write and balance chemical equations using the law of conservation of mass; F differentiate among double replacement reactions, including acid-base reactions and precipitation reactions, and oxidation-reduction reactions such as synthesis, decomposition, single replacement, and combustion reactions; G perform stoichiometric calculations, including determination of mass and gas volume relationships between reactants and products and percent yield; and H describe the concept of limiting reactants in a balanced chemical equation.

On the left is the bar heater with the Digitec yellow thermometer next to it. You could also twist the wire into a loose coil without the turns touching to see if there is an interference from one turn on the next. You could compare this method with some other method for measuring projectile speed time-of-flight, range ; you could look at how the accuracy varies with the relative or absolute mass of the projectile and target, or its speed; or the angle through which the pendulum swings.

Investigating Projectile Motion: Predicting Point of Impact

This increases the likelihood of electron collisions and decreases the current through the conductor. There is a story that other service providers used such bowls to allocate their customer's time.

The student knows that geological phenomena and fluid dynamics affect aquatic systems. I feel strongly that students need to take their learning public and begin to create their digital presence while learning digital literacy. If they heat up then you will have to control the temperature variable but perhaps you could do that by immersing the "leads" in water.

A potato gun is a "firearm". Mohamed pointed out that: 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.

The foreman is the leader, keeping the group on task and focused. However, neither of these forces is heavily dependent on the nose shape.

Assessment tools for group projects

The student knows that biological systems are composed of multiple levels. Students study a variety of topics that include characteristics of matter, use of the Periodic Table, development of atomic theory and chemical bonding, chemical stoichiometry, gas laws, solution chemistry, thermochemistry, and nuclear chemistry.

Temperature and the resistance of wire - Part III One other way to get a reasonable resistance change from copper wire is to use a long length of it. Then with constant illumination, you could put the PV panel on top of a hotplate and crank up the temperature.

You need to know the volume of the marble accurately.§ Implementation of Texas Essential Knowledge and Skills for Science, High School. (a) The provisions of this subchapter shall be implemented by school districts. Measuring the E ects of Air Drag Using Projectile Motion M.

J. Milliman, D. R.

Projectile Launcher

Brown, and S. R. Krutz Department of Physics, Wabash College, Crawfordsville, IN projectile motion, but it is necessary for us to have some mounted our photogates as seen in Fig 1D, separated by. Projectile Motion Lab Problem: How far will a ball land from a table when launched from a known velocity?

PRELIMINARY QUESTIONS 1. If you were to drop a ball, releasing it from rest, what information would be needed to predict. University of Utah – Department of Physics & Astronomy 45 Physics Lab 3 Projectile Motion Room for Your Calculations [3 pts total] Activity 2 – Measuring vo Directly Now, like in your homework, we will want to compare our calculated values of vo with a directly determined value.

Labs are only modified from the point of view of using a motion detector. I do not ever use photogates any more and I suspect Kathy is the same. (useful for determining the velocity of a launched projectile), free fall, determining when I take the pulley off, I can use the photogate as a photogate (like for dropping picket fences for.

components of its motion are governed by the equations used to describe a freely falling object, y= y 0 + v 0yt+ 1 2 g yt2 (2) v= v 0y + g yt; (3) where g y = { m/s2 is the gravitational acceleration.

The vertical and horizontal components of projectile motion are independent from each other.
