It is sometimes claimed that friction forces always slow an object down, but this is not true. If you place a box of mass 2 kg on a moving horizontal conveyor belt, the friction force of the belt acting on the bottom of the box speeds up the box. At first there is some slipping, until the speed of the box catches up to the speed of the belt, which is 6 m/s. The coefficient of kinetic friction between box and belt is 0.50. (a) How much time does it take for the box to reach this final speed? (b) What is the distance (relative to the floor) that the box moves before reaching the final speed of 6 m/s?
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
