Science Recitation Flashcards
Week 9
What is heat?
Heat is energy in transit from a warmer body to a cooler one.
Week 9
What is infrared radiation?
Infrared radiation is the form of heat transfer by electromagnetic waves.
Week 9
What is thermal conduction?
Thermal conduction is the form of heat transfer by the propagation of vibrations of atoms in a solid.
Week 9
What is convection?
Convection is the form of heat transfer by molecular motion in fluids.
Week 10
How is the energy of work transferred from one object to another?
The energy of work is transferred from one object to another by a force acting through a distance.
Week 10
What is a force?
A force is a push or pull, having both magnitude and direction.
Week 10
List the four fundamental forces.
The gravitational force, the electromagnetic force, the strong nuclear force, the weak nuclear force.
Week 10
List the three types of fields.
The gravitational field, the electric field, and the magnetic field.
Week 11
What did Isaac Newton propose in his law of universal gravitation?
Isaac Newton proposed that anything with mass exerts a gravitational force on anything else with mass.
Week 11
What did Albert Einstein propose in his general theory of relativity?
Albert Einstein proposed that anything with mass warps the dimensions of space and time.
Week 12
What causes a gravitational field, and what is affected by gravitational field?
Anything with mass causes a gravitational field. Anything mass and electromagnetic radiation affected by a gravitational field.
Week 12
What causes an electric field, and what is affected by an electric field?
Any charged object causes an electric field. Any charged object is affected by an electric field.
Week 12
What causes a magnetic field, and what is affected by a magnetic field?
