Questions and Answers

Explain the concept of composite force and provide an example from the given text.

Composite force refers to the combination of multiple forces acting on an object. An example from the given text is the demonstration of multiple forces acting on an object by observation and experimentation.

What are the fundamental characteristics of force and how are they used to describe a force?

The fundamental characteristics of force are magnitude (measured with a dynamometer), direction (indicated by arrows), and point of application. These characteristics are used to fully describe a force.

Define the terms 'magnitude' and 'direction' of a force with reference to the text.

Magnitude refers to the strength of a force, measured in Newtons (N), while direction indicates the orientation of the force, represented by arrows.

Explain the concept of balanced and unbalanced forces and how they are observed and compared.

Balanced forces result in no change in the object's motion, while unbalanced forces cause acceleration. They are observed and compared by analyzing the motion of objects through drawings. Signup and view all the answers
