What is PhET mean?
Does “PhET” stand for something? The name “PhET” was originally an acronym for “Physics Education Technology.” However, the PhET site now includes simulations about many other subjects besides physics, so the acronym is too limited.
What is PhET Colorado?
PhET Interactive Simulations, a project at the University of Colorado Boulder, is a non-profit open educational resource project that creates and hosts explorable explanations. It was founded in 2002 by Nobel Laureate Carl Wieman. PhET began with Wieman’s vision to improve the way science is taught and learned.
What is projectile motion PDF?
Projectile motion is a special case of two-dimensional motion. A particle moving in a vertical plane with an initial velocity and experiencing a free-fall (downward) acceleration, displays projectile motion.
How do I make simulations like PhET?
Creating PhET Interactive Simulations Activities
- Define specific learning goals.
- Give only minimal directions on sim use.
- Connect and build on students’ prior knowledge & understanding.
- Encourage students to use sense-making and reasoning.
- Connect to and make sense of real-world experiences.
- Design collaborative activities.
How are PhET simulations made?
To help students engage in science and mathematics through inquiry, PhET simulations are developed using the following design principles:
- Encourage scientific inquiry.
- Provide interactivity.
- Make the invisible visible.
- Show visual mental models.
- Include multiple representations (e.g., object motion, graphs, numbers, etc.)
What is r in projectile motion?
The range (R) of the projectile is the horizontal distance it travels during the motion. Now, s = ut + ½ at2. Using this equation vertically, we have that a = -g (the acceleration due to gravity) and the initial velocity in the vertical direction is usina (by resolving).
What angle do you throw the farthest?
45-degree angle
In most cases you should see that a medium, 45-degree angle made the ball go the farthest. When you throw the ball at a very shallow angle, gravity pulls it down and the ground is closer, which ends the throw sooner so it does not have as much time to travel as far forward.
Is PhET simulation accurate?
PhET simulations allow easy, accurate repeatability (e.g., the skater can always be started from the same point), so that the effect of many different parameters can be accurately explored.
What is projectile launcher?
Launcher The Projectile Launcher is used to investigate important concepts in two- dimensional kinematics. A steel ball placed in the launch barrel can be projected for different launch velocities and launch angles. An easy-to-use dial allows you to set the desired launch angle.
What is equation of projectile?
The equation of the path of the projectile is y = x tan Θ – [g/(2(u2 cos Θ)2)]x2. The path of a projectile is parabolic. At the lowest point, the kinetic energy is (1/2) mu2. At the lowest point, the linear momentum is = mu.
