Fundamental Forces in Nature: The Concept of Force

The video tutorial introduces the concept of force, explaining it through everyday examples like pushing a bike pedal and observing falling leaves. A simple activity with a book, ball, and wall demonstrates how force acts on objects, changing their position or state. The tutorial concludes by defining force as an effect that changes an object's state of motion or direction, measured in Newtons.

• Newton

• Watt

• Joule

According to the conclusion, what does force attempt to change in an object?
