Explore the physics of gravitational force acting on the Apollo 13 spacecraft during its historic mission. This video delves ...

When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).

Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

Friction is a force that always opposes motion. Force is measured in newtons (N). A force is a push or a pull. Contact forces arise between two objects which are in contact. Non-contact forces act ...

You might have noticed that I'm not too fond of the way some textbooks (and shows) word Newton's third law. In fact, I think students get too focused on THE THREE LAWS instead of just modeling force ...

The lack of a suitable experimental setup and a limited number of in vitro investigations have impeded understanding of the factors that have important roles in altering the drag force acting on tiny ...

We’ve probably all experimented with a very clear demonstration of the basic principles of lift: if you’re riding in a car and you put your flattened hand out the window at different angles, your hand ...

Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system. This form of energy has the ...

Unless conditions happen to be windless or unless wind direction is parallel with the vehicle course, the wind acting on a vehicle will approach from a variety of angles relative to the longitudinal ...
