In this short video, I walk you through a simple balloon rocket experiment that is perfect for the classroom or home. Using ...

Students will apply their knowledge of physical science concepts to create a lunar lander game using Scratch. They will use Vernier force and acceleration sensors to understand forces and integrate ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...

Scientists have classified forces into different kinds. Learn more about friction, applied forces and normal forces and how they work on the Earth and in the universe.
