Answers to Coursebook questions – Chapter 4.1
... Any structure has its own natural frequency of oscillation. When the structure is subjected to an external periodic force the amplitude of the resulting oscillations will be the largest when the natural frequency of the system and that frequency of the external force are the same. This is called a s ...

... What drives a car on a horizontal road: fuel inside the car or friction outside between the road and the tyres? We all know the answer, that is until we become physicists! Then we get into problems. A point particle will move from rest or change its velocity only if there is a net external force on ...

... Galileo attempted to prove that objects in free fall accelerate downward at the same rate. This means that no matter what the mass or size of an object is it will still fall at the same acceleration. This free fall acceleration value is -9.81 m/s2. Galileo’s theory only works in a vacuum, however. I ...
