Question:
a. Explain what is meant by the centre of gravity of an object.
b. A flagpole of mass 25 kg is held in a horizontal position by a cable as shown. The centre of gravity of the flagpole is at a distance of 1.5 m from the fixed end.
i. Write an equation to represent taking moments about the left-hand end of the flagpole. Use your equation to find the tension T in the cable.
ii. Determine the vertical component of the force at the left-hand end of the flagpole.

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.
