Slow-motion fire experiment in microgravity done by dropping a box with a GoPro and candle inside. Physics Girl tests a candle in free-fall.

The video explains how air resistance affects the motion of a falling object and eventually causes it to reach a constant speed or terminal velocity. The first law of motion is applied to demonstrate the decrease in acceleration as the...

This video explains the concept of terminal velocity using velocity time graphs. The video starts with a brief recap of how the force acting on a free falling object changes over time. The video then explains how air resistance affects a...

This video explores the behavior of objects when they fall under gravity. It starts with a quick recap of Newton's Second Law, which explains the relationship between force, mass, and acceleration. The video then looks at how weight is...

This is a lecture video on Newton's first law that explains how the force applied to objects affects their motion. The video starts with a recap of forces and how multiple forces can be combined to give a resultant force. The video then...

The video focuses on the concept of energy dissipation and how it occurs in various systems. It begins by explaining the principle of conservation of energy and then goes on to provide examples of closed and open systems. The video then...

A force is a push or a pull that acts on an object.



Forces are vector quantities because they have both magnitude and direction, and so can be represented by an arrow. Scalar quantities have only magnitude and no...

The results are in – gravity is weaker than it should be! Lotus is certain that someone is digging a giant cave underneath the Big Apple, but Mark isn’t convinced. Who do you think is correct? This lesson will assess the accuracy,...

As the city gets devoured by the sinkhole, Vector Man investigates its suspicious origin. Does he have enough time to salvage the evidence? This lesson will debunk the most commonly held misconceptions about acceleration....

Take a slow motion look at what actually happens when a water balloon bursts.

The acceleration and terminal velocity of a dropped object are determined. The motion graphs of dropped coffee filters are demonstrated. Terminal velocity of a baseball is determined. Numerical Modeling is previewed. Want Lecture
