Question:
It is believed that much of the mass in the universe is carried by what is called dark matter, matter that does not emit enough visible light or other radiation to be detected by conventional telescopes.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
