Physics Quiz: Gravity and Heat Transfer

A fundamental interaction that causes objects with mass to attract each other.

The amount of matter in an object. The larger the mass, the stronger the gravitational pull.

A region of spacetime where gravity is so strong that nothing, not even light, can escape.

The transfer of heat through direct contact between objects of different temperatures.

The transfer of heat by the movement of a heated fluid, such as air or water.

The transfer of heat through electromagnetic radiation, such as light or infrared waves.

Materials that allow heat to flow easily through them.

Materials that resist the flow of heat through them.

A buildup of electrical charge on a surface, often caused by friction.

The flow of electrical charge, often through a conductor.

A measure of the amount of electrical charge contained in an object.

Newton's law of universal gravitation states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Einstein's theory of relativity is a theory of spacetime that describes the relationship between gravity and the universe. It includes the special relativity theory, which describes the relationship between space and time, and the general theory of relativity, which describes gravity.

The difference between conduction and convection is that conduction involves heat transfer through direct contact, while convection involves heat transfer through the movement of a fluid.

The difference between current and static electricity is that current electricity is the flow of electrical charge, while static electricity is a buildup of electrical charge.
