- Centripetal force (video) | Orbital motion | Khan Academy
A centripetal force acts perpendicular to an object's velocity A centripetal force causes an object to accelerate by changing direction and following a curved path The centripetal force points towards the center of the curve, and the object's velocity is tangent to the curve
- Learn and try: Circular motion (article) | Khan Academy
Centripetal force, for an object in circular motion, is just the force maintaining the circular motion, the force that prevents the object from flying away tangentially
- Learn and try: Circular motion (article) | Khan Academy
Learn how to analyze forces and acceleration for an object moving along a circular path
- Centripetal force (video) | Orbital motion | Khan Academy
A centripetal force acts perpendicular to an object's velocity A centripetal force causes an object to accelerate by changing direction and following a curved path The centripetal force points towards the center of the curve, and the object's velocity is tangent to the curve Centripetal force is not a type of force, but a role that can be played by different forces Gravity acts as the
- Physics archive | Science | Khan Academy

- Centripetal forces review (article) | Khan Academy
Review the key concepts, equations, and skills for centripetal forces, including that centripetal force is the net force in the radial direction
- Centripetal force problem solving (video) | Khan Academy
In this video David gives some problem solving strategies for centripetal force problems and explains many common misconceptions people have about centripetal forces
- Learn and try: Circular orbits (article) | Khan Academy
Learn how to describe the motion of objects following circular orbits at constant speed An object that's experiencing a centripetal force follows a curved path In some cases, an object may experience a centripetal force long enough to only complete a single revolution around a curved path, such as a roller coaster that completes a 360 ∘ loop
