Light/Waves2
The reflected ray is always reflected at the same angle as the incidence ray.
What is the law of reflection
Light bending around a corner or opening
What is difraction
Objects in motion tend to stay in motion unless acted upon by an external force
What is Newton's first law
The energy of motion. 1/2(m*v^2)
What is Kinetic Energy
Force*Distance
What is the formula for work
The area above the middle of an earthquake
What is the epicenter.
Light bouncing off of an object
Force=mass*acceleration. The acceleration of an object is directly proportional to the force acting on it.
What is Newton's second law
Stored energy due to position above the Earth. Mass*9.8*Height=joules
What is GPE
(40kg)*(8m/s)=320N
What is the force of a 40kg object moving at (8m/s)^2
The actual place in the earth where an earthquake occurs.
What is the focus.
Light changing angles as it passes from a more dense medium to a less dense medium or vice versa.
Every action has an equal and opposite reaction. When you push a wall, the wall pushes back at you with the same force.
What is Newton's third law.
The average KE of particles in an object
What is temperature
Work/Time, if you do 320J of work for 10 seconds you would use 32 Watts of power.
What is the formula for power
radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
What is the EM spectrum.
The faster wave in an earthquake, it is a compression wave.
What is a P (primary) wave.
A push or pull on an object.
What is Force
What is thermal energy.
If two objects do the same amount of work, the one that did it in a shorter time used less power.
What is applying the formula for work.
Red, Orange, Yellow, Green, Blue, Indigo, Violet
What is the visible light spectrum.
The slower wave in an earthquake, it is a transverse wave.
An object at rest
What is a balanced force.
Energy cannot be created or destroyed
What is the law of conservation of energy
A force that causes the displacement of an object.
What is work
