…dipole-dipole attraction. When oil and water are mixed, the dipole-dipole interactions are disrupted, but constant molecular motion allows the stronger dipole-dipole attractions to partition the polar molecules from the mixture….
…load. This model graphs both the parachute’s height above the Earth’s surface and its speed after it is released. Motion continues until a constant speed is achieved, the terminal velocity….
Explore what happens when a force is exerted on a polymeric plastic material. There are many different types of materials. Each material has a particular molecular structure, which is responsible…
Explore what happens when a force is exerted on a metallic material. There are many different types of materials. Each material has a particular molecular structure, which is responsible for…
Explore connections between electric forces and molecules using simulations, and explain energy transfers using the conservation of energy.
Observe the direction of forces between a negatively charged Van de Graaff generator and a positively charged object.
Explore how different elements come together to form bonds and compare changes in potential energy and forces.
…are attracted through a London dispersion attraction; the strength of the attraction depends on the shapes and sizes of the interacting molecules. The force of attractions between molecules has consequences…
Explore the balance of forces and electron distribution as two atoms are moved closer and further apart.
Explore the strength and direction of forces between two charged objects by observing the color and direction of the force pointers.
