Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to...

This content analyzes the normal force on a driver in a car moving at a constant speed over a circular hill and into a valley. By first using the condition of zero normal force at the top of the hill to determine the centripetal force,...

This video solves a physics problem about a car accelerating on a circular track, demonstrating how to calculate its net linear acceleration and the angle it makes with the car's velocity.

Discover the fundamental reason why centripetal force always acts perpendicular to an object's velocity in circular motion. This video uses a clear visual example to illustrate this key physics concept.

This content analyzes a physics problem involving a ball connected by two strings to a rotating vertical rod, undergoing circular motion. It demonstrates how to calculate the tension in the lower string, the net force on the ball, and...

Why is there a “center seeking” centripetal acceleration? A step-by-step walk through of the answer to this question.

Who doesn't love mini-golf? Especially when you've got money riding on it, and especially when you've got some physics knowledge up your sleeve. Go ahead and impress your friends by getting through the windmill obstacle, thanks to a...

This nugget explains the mathematical expressions for force for uniform circular motion.

Calculus based review of instantaneous and average angular velocity and acceleration, uniformly angularly accelerated motion, arc length, the derivation of tangential velocity, the derivation of tangential acceleration, uniform circular...
