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: ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

The film explains the concept of uniform motion, highlighting that it involves an object moving in a straight line at a constant speed. Examples include a jet and a car that move equal distances in ...

If your students like sports, rockets and roller coasters, then they’ll like Sir Isaac Newton! Newton’s Laws will help your students understand force, motion, and the transfer of energy. In this ...

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 ...
