What else can I help you with?
Do all objects have physical properties?
Yes, all objects have physical properties. Physical properties are characteristics that can be observed or measured without changing the composition of the object, such as color, shape, size, density, and texture.
Are 'time' and 'space' physical objects?
No, they are not objects at all. They are abstract concepts we use in reference to objects. We cannot perceive them with our senses. They are nonphysical. They are just measurements we use to quantify physical objects that we can perceive.
What is heat quantity?
Heat quantity refers to the amount of thermal energy transferred between two objects due to a difference in temperature. It is usually measured in units of joules or calories. Heat quantity is commonly used to describe the amount of heat exchanged during a physical or chemical process.
Which force exists between objects in the absence of direct physical contact?
Gravitational force exists between objects in the absence of direct physical contact. This force is a result of mass and distance between objects, attracting them towards each other.
Can an electro magnetic field repel physical objects?
Yes, an electromagnetic field can repel physical objects if the objects are ferromagnetic (contain iron) and the field is strong enough to overcome the force of gravity or any other forces acting on the objects. This is the principle behind magnetic levitation and magnetic repulsion systems.
What is a physical object that can be exchanged?
Goods are physical objects that can be exchanged.

Is there anything that isn't a physical object?
All objects are physical. Things that are not physical are abstract.
What is the opposite of coral?
Coral is a physical object, and physical objects do not have opposites.
What are some of the things atronomers can learn about astronomical objects from their spectra?
The main physical information about astronomical objects give their spectra!
The detection of physical energy emitted or reflected by physical objects is called?
The detection of physical energy emitted or reflected by physical objects is called remote sensing. This technology is used to gather information from a distance by recording and analyzing the energy that is emitted or reflected by objects on the Earth's surface.
Would sugar crystals be physical science?
Sugar crystals are physical objects.
What is MEASURE of an objects physical makeup?
a stopwatch
