Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
False. Magnetic interactions can occur even when the interacting objects are not touching. Magnetic fields can exert forces on objects at a distance, such as between a magnet and a piece of metal.
False. All objects with mass exert gravitational forces on each other, not just the Earth.
False. Every object attracts every other object, through the gravitational force.
No, an object cannot exert a force on itself. The concept of self-exerted force is not supported by the laws of physics. Objects can only experience forces from external sources, which can impact their motion or stability.
Contact forces, such as friction, normal force, tension, and applied force, only have an effect on objects they touch. These forces require physical contact between objects to manifest and influence the motion or deformation of the objects involved.
Forces can act on an object without touching it through fields. In the case of gravitational forces, objects are attracted to each other through gravitational fields, without physical contact. Similarly, magnetic or electric fields can exert forces on objects without direct contact.
False. Forces can also set stationary objects in motion.
No...
Inverting? I assume you mean the surrounding medium, or the medium in between. No; the gravitational force depends ONLY on the masses, and on the distance. Of course, anything between the two objects may exert forces OTHER than the gravitational force.
The boolean operation that keeps only the volume common to two solid objects is the intersection operation. This operation creates a new object that consists only of the overlapping region of the original objects.
No, it is just Carbon dioxide in solid state (converted from gas directly to solid by sublimation). No ionic forces present. These are van der wall forces only.
Yes, it is true that a magnet is an object that can exert force on another material. However, it will only exert that force if it is made out of the correct material. Items made of iron are the most common magnetic objects.
