Can sound move objects?
Yes, sound can move objects through a phenomenon called acoustic levitation, where sound waves create pressure that can lift and move objects.
Is it easier for a tornado to lift heavier objects or lighter objects?
Tornadoes are more likely to lift lighter objects as they generate an upward force with their strong winds. Heavier objects may be more difficult for tornadoes to lift unless they are caught in the vortex of the tornado's winds.
What is a force which pushes things up?
The force that pushes things up is called lift. It is the force that acts perpendicular to the direction of the flow of a fluid (such as air or water) and helps objects to rise or stay airborne. This force is commonly associated with flying objects like airplanes and birds.
How can the tension rope pulley be used to efficiently lift heavy objects?
The tension rope pulley can be used to efficiently lift heavy objects by distributing the weight of the object across multiple pulleys, reducing the amount of force needed to lift it. This allows for a mechanical advantage, making it easier to lift heavy objects with less effort.
What is a machine made of wheels and string called?
It is called a pulley system. Pulleys consist of a wheel with a groove and a rope or belt that fits into the groove to transfer motion or lift objects.
