At the instant of Figure a 2.0 kg particle P has a position vector r of magnitude
Question:
At the instant of Figure a 2.0 kg particle P has a position vector r of magnitude 3.0 m and angle ?1 = 45? and a velocity vector r of magnitude 4.0 m/s and angle ?2 = 30?. Force F, of magnitude 2.0 N and angle ?3 = 30?, acts on P. All three vectors lie in the xy plane. About the origin, what are the(a) Magnitude and(b) Direction of the angular momentum of P and the(c) Magnitude and(d) Direction of the torque acting on P?

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.
