... The concept of force can be taken from our daily experience. Although forces cannot be seen or directly observed, we are familiar with their effect. In Statics, bodies at rest are investigated. E.g. To prevent a stone from falling, to keep it in equilibrium, we need to exert a force on it, for examp ...

... 4. What happens when you apply a force to an object at rest? You change the motion of the object – it will move. 5. How does friction (air resistance) affect the motion of an object? Friction opposes motion – prevents it. 6. Explain what happens when a person wears a seat belt and when he or she doe ...
