FAQs on Video: Air Resistance Video Lecture - IGCSE Cambridge Science for Year 6 - Class 6

1. What is air resistance?
Ans. Air resistance is the force that opposes the motion of an object as it moves through the air. It is caused by the collisions between the object and air molecules.
2. How does air resistance affect the motion of objects?
Ans. Air resistance slows down the motion of objects by exerting a force in the opposite direction of their motion. This force increases as the speed of the object increases.
3. How can air resistance be reduced?
Ans. Air resistance can be reduced by changing the shape of the object to make it more aerodynamic. Smooth surfaces and streamlined designs can help minimize the effects of air resistance.
4. Does air resistance affect all objects equally?
Ans. No, air resistance affects objects differently depending on their size, shape, and speed. Larger and less aerodynamic objects experience greater air resistance compared to smaller and more streamlined objects.
5. Can air resistance ever be completely eliminated?
Ans. It is impossible to completely eliminate air resistance, but it can be minimized by designing objects with aerodynamics in mind and reducing their speed.
