In this guided inquiry demonstration, a person on rollerblades and a medicine ball are used to teach the concept of conservation of momentum. Various sorts of collisions are used to show how momentum is conserved within a system.
This simulation shows the difference between Constant Velocity vs. Constant Acceleration هذه المحاكاة تبين الفرق بين السرعه الثابته والتسارع المستمر في الفيزياء
The simulation shows five different motions in which objects experience constant acceleration, starting from rest. Although each motion is different, the underlying physics is the same. What features of the simulation reinforce the idea that the physics is the same?
This worksheet provides students practice answering concept questions and solving problems involving momentum and impulse.
This activity is a part of the lesson plan "Shoes Under Pressure". In this activity students will design and build shoe prototypes that convert between high heels and athletic shoes. They apply their knowledge about the mechanics of walking and running as well as shoe design (as learned in the associated lesson) to design a multifunctional shoe that is both fashionable and functional.
This student handout is a supplemental resource to be used with the "Kinetic Energy Lab." The purpose of this lab is to investigate the relationship between mass, speed and energy.
This is designed as a challenging PLTL workshop in calculus-based introductory physics. It may also serve as as module in workshop physics. This is intended to indicate to the student the level of mathematical skill appropriate upon finishing the introductory courses in physics, and to encourage them to reach for this level of mathematical rigor. Text, problem sets, and associated activities are provided.
Students will observe qualitatively the relationship between electrical charge and force and determine experimentally the quantitative relationship between force and the center to center distance between charged objects.
Students explore the forces acting on a pair of charged particles. They can adjust the charge on each ion and move the ions to see the force acting between them.
Students will demonstrate their understanding of Coulomb's law and the way it governs the interaction between charged particles, by effectively describing these ideas using words and sketches.
In this activity, students will use Coulomb's law and vector principles to determine the number of electrons which are transferred to a balloon as the result of 10 average-strength rubs on animal fur. Students will complete a formal lab write-up at the conclusion of the activity.
Sample Learning Goals
Relate the electrostatic force magnitude to the charges and the distance between them
Explain Newton's third law for electrostatic forces
Use measurements to determine Coulomb’s constant
Determine what makes a force attractive or repulsive
This activity is based on the Curiosity launch video and prompts students to make basic kinematic measurements and calculations based on the video, including elapsed time, displacement, starting velocity, average velocity, final velocity, and acceleration.
Students will be given a bag of materials and asked to find out how a current-carrying coil is influenced by a magnetic field. They will also construct models of galvanometers and DC motors using film cannisters.
Students explore AC/DC currents and determine one new fact about electricity. They will write a paragraph describing what materials they used and what they discovered.
In this unit, students will learn how two or more electrical devices can be connected to form an electric circuit. Lessons in this unit include: Circuit Symbols and Circuit Diagrams; Two Types of Connections; Series Circuits; Parallel Circuits; and Combination Circuits. This unit also includes videos, animations, and mini quizzes to check for understanding and facilitate learning.
In this unit students will learn about electric circuits and electric current power. The unit will teach students the anatomy of the light bulb and how to build closed circuits. Students can self assess their understanding of concepts by answering questions at the end of each section.
In this unit, students will learn why charge flows through wires of electric circuits and the variables that affect the rate at which it flows. Lessons in this unit include: Electric Field and the Movement of Charge; Electric Potential; and Electric Potential Difference. This unit includes videos, animations, and mini quizzes to check for understanding and facilitate learning.
In this unit students will learn about resistance, current, and power. Students will look at different series and parallel circuit illustrations in relation to Ohm's law (voltage, resistance, and current). Lessons in this unit include: Journey of a Typical Electron; Resistance; and Ohm's Law. This unit includes questions at the end of each section to allow students to self assess and check for understanding.
In this lesson, students will work collaboratively to create a presentation featuring an electrostatics demonstration. The demonstration should deal with some aspect of the three basic principles of electrostatics. Each group will also submit a written descripton of their demonstration.
