You are trying to raise a bicycle wheel of mass m and radius R up over a curb of height h. To do this, you apply a horizontal force F (Fig. 11.52). What is the smallest magnitude of the force F that will succeed in raising the wheel onto the curb when the force is applied?
(a) At the center of the wheel, and
(b) At the top of the wheel?
(c) In which case is less force required?

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.
