Vector addition - Simulation

By Sandile MHlophe -
  Topics Vectors Vector Components Vector Addition Equations Description Explore vectors in 1D or 2D, and discover how vectors add together. Specify vectors in Cartesian or polar coordinates, and see the magnitude, angle, and components of each vector. Experiment with vector equations and compare vector sums and differences. Sample Learning Goals Describe a vector in your own words Explain a method to add vectors Compare and contrast the component styles Decompose a vector into components Describe what happens to a vector when it is multiplied by a scalar Arrange vectors graphically to represent vector addition or subtraction

Molecular and light - Simulation

By Sandile MHlophe -
  Topics Molecules Photons Absorption Light Description Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our pan and zoom feature, so zoom in for a closer look, if you need to. Sample Learning Goals Explore how light interacts with molecules in our atmosphere Identify that absorption of light depends on the molecule and the type of light Relate the energy of the light to the resulting motion Identify that energy increases from microwave to ultraviolet Predict the motion of a molecule based on the type of light it absorbs Identify how the structure of a molecule affects how it interacts with light
