Khan Academy: Identifying Centripetal Force for Cars and Satellites

Identifying forces or force components acting as the centripetal force for a ball on a string moving in a horizontal circle. [5:05]

Circular motion can make you loopy! On this physics worksheet, learners practice solving problems regarding centripetal force, rotational period, speed, acceleration, and more. A flying aerobat and a couple of amusement park rides make...

Beginning physicists imagine being aerospace engineers by solving seven centripetal force problems. They calculate the work, speed, time, and acceleration of objects in orbit: a satellite around Earth, and Earth around the sun. This is a...

Disciples of physics practice solving acceleration and centripetal force problems. They construct qualitative motion maps and quantitative force diagrams in addition to using their critical thinking skills. Get your class moving by...

This article explains the buoyant force using a submarine as an example. It also discusses what determines the size of the buoyant force using a formula, and explains decompression sickness better known as the bends.

Sal defines and compares tension, weight, friction and normal forces using free body diagrams. [8:03]

Review the key concepts and skills for forces, including how to draw free body diagrams.

Looks at how to discern whether molecules are polar or non-polar, and how to apply that polarity to intermolecular forces. [8:35]

When multiple forces are acting on a particle, we'll need to express them as a single force known as a net force. [1:59]

A worked example finding all force vectors acting on a pendulum moving in a horizontal circle. [2:58]
