Thermal Energy
This is the total energy of all the moving particles in a substance.
What is thermal energy.
This type of energy is energy of motion.
What is kinetic energy?
This force opposes motion between two surfaces that are touching.
What is friction?
When light bounces off a surface, it is called this.
What is reflection?
A push or a pull on an object is called this.
What is a force?
This type of heat transfer occurs when particles bump into each other directly.
What is conduction?
A stretched rubber band has this type of stored energy.
What is elastic potential energy?
If forces acting on an object are balanced, this happens to its motion.
What is it stays at rest or continues at constant speed?
When light bends as it passes from air into water, it is called this.
What is refraction?
Light travels in these straight paths.
What are (light) rays?
This type of heat transfer occurs through electromagnetic waves and does not require matter.
What is radiation?
When a roller coaster goes down a hill, potential energy changes into this form of energy.
What is kinetic energy?
When a moving object hits a wall and changes shape, energy is transferred into this form.
What is deformation (or elastic potential energy or thermal energy)?
This part of the electromagnetic spectrum is visible to the human eye.
What is visible light?
Shorter wavelengths of visible light, like violet, have this compared to longer wavelengths like red.
What is higher energy?
When a substance changes from liquid to gas, particles move farther apart and this increases.
What is particle motion (or kinetic energy)?
When you rub your hands together and they get warm, motion energy transforms into this type of energy.
What is thermal energy?
Increasing an object’s mass while keeping speed the same will increase this in the system.
What it's total energy?
A two-way mirror works because part of the light is reflected and part is __.
What is transmitted (passes through)?
According to this scientific law, energy cannot be created or destroyed, only transformed.
What is the Law of Conservation of Energy?
If two objects are in thermal equilibrium, this is true about their temperatures.
What is they are the same temperature?
In a flashlight, chemical energy from the battery transforms into these two main forms of energy.
What are light energy and thermal energy?
A diagram that uses arrows to show all the forces acting on an object is called this.
What is a free body diagram?
When white light passes through a prism and spreads into a rainbow, this process is occurring because different wavelengths bend at different angles.
What is dispersion?
In this type of heat transfer, warmer, less dense fluid rises while cooler, more dense fluid sinks.
What is convection?
