Final Jeopardy Final Jeopardy Category EMS (Electromagnetic Spectrum)

Final Jeopardy What is radio, microwave, infrared, visible spectrum, ultraviolet, x-rays, and gamma rays? List the wave types of the electromagnetic spectrum from longest to shortest wavelength.

$200 What is Point A? This point of the coaster would have the greatest PE.

$400 What is the KE decreases going from point B to point C. This is what happens to the KE from point B to C.

$600 What is chemical to thermal to chemical to mechanical? Trace the energy conversions that would take place when you use a charcoal grill to cook a hamburger that you will eventually eat.

$800 What is PE = mgh which is PE = 5 kg 9.8 m/s 2 12 m = 588 Joules ? A 5 kg cat is stuck on a roof 12 m high. This is the cat’s energy. (Include units.)

$1000 What is KE = ½ mv 2 which is KE = ½ 25 kg (5 m/s) 2 = Joules ? A 25 kg dog is running at a speed of 5 m/s. This is the dog’s energy. (Include units.)

$200 What is Newton’s First Law of Motion? This picture illustrates this law of motion.

$400 What is 300 N? If the player on the right is pushing with 300 N of force, the player on the left pushes with this much force when the ball does not move.

$600 What is B.? It has the most mass. Of the following, the one with the greatest inertia. A) baseball B) bowling ball C) pencil D) ping-pong ball E) toothpick

$800 What is as the mass increases the acceleration decreases? It is an indirect/inverse relationship. The following graph shows the relationship between mass and acceleration in terms of Newton’s 2 nd Law. This is the relationship between these variables.

$1000 What is a = F/m which is a = 250 N ÷ 70 kg = 3.57 m/s 2 ? This is the rate a swimmer will accelerate off the wall when she pushes off the wall with a force of 250 N and she weighs 70 kg. (Remember the circle diagram.)

$200 What is the object is not moving? This is the motion of the object represented in this graph. Distance Time

$400 What is positive acceleration or increasing speed? Describe the motion of this object. Speed Time

$600 What is negative acceleration or decreasing speed? Describe the motion of this object. Speed Time

$800 What is no, the slope of swimmer B changes? Did all of the swimmers swim at a constant speed? Explain.

$1000 What is zero acceleration or constant speed? Describe the motion of this object. Speed Time

$200 What is a solid? The movie clip from Stand By Me illustrated that you can hear sound through this type of medium the fastest.

$400 What is you can not hear an explosion in space because sound needs a medium to travel through? Star Wars shows the Death Star being destroyed in a thundering explosion. This is the reason why the person responsible for the research on this shot should be fired.

$600 What is as the wavelength increases (gets longer), the frequency and energy decrease and vice versa? This is the relationship between wavelength, frequency, and energy.

$800 What is constructive interference?

$1000 What is a straight line? This is what the resulting wave would look like when destructive interference happens.

$200 What are balanced forces? This is what we call forces that are equal in size but opposite in direction.

$400 What is v = d/t which is v = 10 m ÷ 20 s = 0.5 m/s ? A mail truck takes 20 s to move between mailboxes that are 10 m apart. This is the mail truck’s average speed.

$600 What is friction? This force acts between two objects that are in contact with one another.

$800 What is a = v f – v i ÷ t which is a = 24 m/s – 4 m/s ÷ 4 s = 5 m/s 2 ? Riding a bike down a hill, your speed increases from 4 m/s to 24 m/s in 4 s. This is your acceleration.

$1000 What is a direct relationship? (As the force increases, so does the acceleration of the object.) This graph shows the relationship between force and acceleration of an object according to Newton’s 2 nd Law. This is the relationship.

$200 What is radiation? This is how energy from the Sun reaches the Earth.

$400 What is conduction?

$600 What is convection?

$800 What is a liquid or a gas? Convection is likely to occur in these two phases of matter.

$1000 This is how I taught you to remember the differences between the three types of heat transfer. What is the D in conduction stands for the direct contact of particles, convection occurs in liquids and gases, while radiation does not require a medium?

Daily Double What is a direct relationship? (As the force increases, so does the acceleration of the object.) This graph shows the relationship between force and acceleration of an object according to Newton’s 2nd Law. This is the relationship.
