In Figure a cord runs around two massless, frictionless pulleys. A canister with mass m = 20
Question:
(a) What must be the magnitude of F if you are to lift the canister at a constant speed?
(b) To lift the canister by 2.0 cm, how far must you pull the free end of the cord? During that lift, what is the work done on the canister by
(c) Your force (via the cord) and
(d) The gravitationalforce?

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.
