Varies in intensity
Travels in straight lines
Bounces or bends when it hits objects
Name both parts of Newton’s First Law.
An object at rest stays at rest unless acted on by an unbalanced force.
Define Radioactive.
When an atoms nucleus is unstable and begins to decay.
Define Kinetic energy.
Energy of motion.
Define Period.
Time it takes for one cycle to happen (seconds).
Define Incandescence.
A process that makes light with heat.
Define Inertia.
Resistance to change.
Define Radioactive Decay.
When the nucleus becomes unstable and spontaneously emits particles to become more stable.
Define Potential energy.
Stored energy due to position or molecular structure.
Define Frequency.
Number of cycles per second.
Define Fluorescence.
A process that makes light when the energy is provided by electromagnetic radiation (ultraviolet light).
Tell me the definition of Newton’s Second Law.
The more mass/acceleration something has, the more force it will produce.
Define Alpha Decay.
