Newtons 3rd Law can be easily summed up with this statement; Every _____________ causes an equal and opposite ___________.
What is Action and Reaction?
100
Measurement unit for Work.
What is Joules?
200
Which concept states that momentum can be transferred between inteacting objects, but the total amount of momentum remains the same?
What is Conservation of Momentum?
200
Sliding friction is not influences by this characteristic. (mass, surface texture, or surface area)
What is Surface Area?
200
This subatomic particle is negatively charged, has nearly no mass, and is not found in an atoms nucleus.
What is an electron?
200
Larger masses and shorter distances increase this laws attraction.
What is the Universal Law of Gravitation?
200
In order for work to occur, what two factors must be occuring in the same direction?
What is Force direction and Motion direction?
300
In order to find an objects ___________,you multiply its mass by its velocity.
What is Momentum?
300
Speeding up, slowing down, and changing direction are all examples this portion of Newtons 2nd Law.
What is Acceleration?
300
John Dalton created Atomic Theory which states,
What is all substances are made of atoms, atoms of the same element are alike, and atoms join with other atoms to make new substances.
300
According to this Law, the volume inside a closed environment will decrease when the pressure applied to it increases.
What is Boyles Law?
300
Power is . . . . .
What is the rate that work is being done. (how fast)
400
Dry Ice does not melt. It change of state from a solid directly to a gas is called _________________.
What is Sublimation?
400
The momentum of an object (how easily it can be stopped or re-directed) is based on these two factors.
What is Mass and Velocity?
400
The atomic number of an element (ie; Carbon's is 6, Oxygen's is 8) refers to the number of this positively charged subatomic particles located in the nucleus.
What is a Proton?
400
The reason a balloon will eventually explode if left in the sun too long demonstrates this law of increased temperature = increased volume.
What is Charles Law?
400
Explain why carring a suitcase in your hand from your car to the terminal is or is not work.
What is not work because the direction of the force keeping the suitcase in your hand is upward, yet the movement of the suitcase is forward. Since the two directions are not the same, work is not being done.
500
Forces that produce a change in motion.
What is Unbalanced Force? (result of net forces)
500
Which has more momentum? A golf ball with a mass of 250 grams moving at 40 m/s or a 4 kg bowling ball moving at 4 m/s?
What is a 4 kg bowling ball moving at 4 m/s (M = 4kg x 4 m/s = 16 kg m/s)
500
Isotopes are atoms of the same element which have the same atomic number, but the number of these subatomic particles is different.
What is a Neutron?
500
Increasing the speed of a fluid moving over a surface decreases the amount of pressure being applied to the surface.
What is Bernoulli's Principle?
500
The amount of force (N) needed to lift an object is equal to the gravitational attraction of that object (its mass in kg). Explain how to convert your weight into Newtons.
What is divide weight in pounds by 2.2 to get kg, which equals the amount of force (N).
