Two blocks of mass m 1 and m 2 are sliding down an inclined plane (Fig. P4.79).
Question:
Two blocks of mass m1and m2are sliding down an inclined plane (Fig. P4.79).
(a) If the plane is friction less, what is the magnitude of the contact force between the two masses?
(b) If the coefficient of kinetic friction between m1 and the plane is µ1 = 0.25 and between m2 and the plane is µ2 = 0.25, what is the contact force between the two masses?
(c) If m1 = 0.15 and m2 = 0.25, what is the contact force?

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.
