Term the Definition
Anything made up of atoms or parts of atoms.
What is matter?
What equation would you use for the following problem: A train travels 25.1 miles in 0.50 hr, solving for velocity.
What is d = vt? or more accurately v = d/t
This CDA staff member unintentionally spiked a duck.
Who is Mrs. Goodnough?
Two billard balls with the same mass and weight collide.
Elastic collision
A space ship cruises at a constant velocity of 33,155 km/hr for 22.5 minutes. If solving for the unknown distance, what equation will you use?
v = d/t
The product of an object's mass and velocity.
What is momentum?
What equation would you use for the following problem: Consider a car with a mass of 1880 kg. How much force does it take to give this car an acceleration of 1.50 m/s2?
What is a = F/m ?
This CDA staff member has studied taekwondo, karate, judoka, jujitsu and kung fu.
Who is Mrs. Gallaway?
Two cars, same make, model, and year, are travelling toward each other in a straight path at 35 miles per hour.
Inelastic collision.
A driver accelerates her car from rest to a velocity of 35.9 mi/hr in 8.2 seconds. If solving for the unknown acceleration, what equation do you use to solve this?
a = vf - vi /t
A positively stated, informed prediction about what will happen in certain circumstances. In other words, a prediction that results when a theory is applied to a particular situation.
What is a hypothesis?
What equation would you use for the following problem: a space ship travels 8.96 x 10(9th) km at 3.45 x 10 (5th) m/s, solving for time.
What is d = vt or more accurately, t = d/v
This CDA staff member was interrogated by the FBI in the principal's office while in high school.
Who is Mr. Johnston/Pastor Brandon?
Newton's cradle, 2 stainless steel balls collide with the other stationary stainless steel balls.
Elastic collision.
The enginge in a model rocket can deliver a thrust (force) of 11.87N, and the mass of the rocket is 196.5g. If solving for the unknown acceleration, what equation do you use?
a = F/m
The book's glossary defines this as: one of the basic constituents of the universe, the others being matter and intelligence. Another way this term is described is: "the capacity to do mechanical work".
What is energy?
What equation would you use for the following problem: a proton is uniformly accelerated from rest to 80.0% of the speed of light in 18 hrs, 6 minutes, 45 seconds, solving for acceleration.
What is a = vf - vi/t
This CDA staff member didn't learn to swim until they were in college.
Who is Mrs. Palmer?
A human cannonball is fired out of his cannon, and performing his stunt well, lands on his crash pad with no harm done to himself.
Inelastic collision.
A standard baseball has a mass of 144.3g. If solving for the unknown weight (in Newtons), what equation do you use?
Fw = mg
The process of using experiment, observation and logical thinking to build mental models of the natural world.
What is science?
What equation would you use for the following problem: A missile with a mass of 45,500 kg is accelerated from rest to 55 m/s in 6.4 seconds, solving for acceleration.
What is a = vf - vi/t
This CDA staff member has been through the Panama Canal three times.
Who is Mr. Davidson?
Two protons are accelerated and fired at each other in the Large Hadron Collider in Switzerland.
Inelastic collision.
(The protons are accelerated and fired at each other and break apart into smaller particles.)
A proton with a mass of 1.675 x 10-24g is accelerated from rest to 15.750km/s in a time interval of 45.000 x 104ms. If solving for the unknown force, what TWO equations do you need to solve this problem.
a = vf -vi /t
AND
a = F/m
