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 ...

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 ...

Discover the physics behind motion with Understanding Friction Coefficient and Force Required to Move a Block. Learn how friction influences movement and how to calculate the force needed to overcome ...

Explore the difference between calculated forces and constraint forces in this physics-focused video! Learn how to identify, compute, and distinguish between the forces acting on objects, including ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...
