Model how electric fields change due to the number and placement of charged objects.
…commonly helical coiled metal devices. When a spring is compressed or stretched and then released, it will vibrate at a particular frequency. This frequency is called the period of the…
Explore what happens when a force is exerted on a rubber tire. There are many different types of materials. Each material has a particular molecular structure, which is responsible for…
Drag the location of charges to get a positively charged particle to the target while observing forces and fields.
Manipulate the magnitude of charges on two objects to get a third positively charged particle to hit a target.
How do scientists detect planets around distant stars? Use this model to explore how a star’s movement and light intensity are affected by an orbiting planet. Explore the effects of…
Compare the electron distribution, potential energy, and forces of two interacting hydrogen atoms (which can bond) with two helium atoms (which do not).
…the weight, the angle at which the pendulum is released and the friction (or damping force) exerted on the pendulum. Which of these factors affect the period of the pendulum?…
…polar molecules are attracted through both the London dispersion force and the stronger dipole-dipole attraction. The dipole-dipole attraction is often thought of as “opposite charges attract; like charges repel.” The…
…a London dispersion attraction; polar molecules are attracted through both the London dispersion force and the stronger dipole-dipole attraction. The force of attractions between molecules has consequences for their interactions…
