Newton's Laws (new2you)
100
scalar quantities have this.
What is magnitude?
100
The formula for acceleration.
100
The straight line slope of a position-time graph equals
What is constant velocity?
100
Name that physics tool: (explain how it's used in physics)
What is a computer? They are used for plotting data, graphing stuff, connecting devices like photo gates or motion detectors. A rare sight indeed around here.
100
the basic unit of Force
what is the NEWTON?
200
vector quantities have these.
what is direction and magnitude?
200
changing velocity in the positive direction ("speeding up").
what is acceleration (positive slope)?
200
The curved slope of a position-time graph equals
What is acceleration?
200
Name the tool. (be sure to explain how it's used-hint: metric system, no yards)
What is a meter stick? The meter stick is good for measuring distances.
200
An object's tendency to resist changes in motion
(waiter pulling table cloth from fully set table)
(wearing seatbelt/not wearing seatbelt and hitting a pole)
What is intertia?
300
classify as scalar or vector quantities: (in order)
1. Velocity 2. Speed 3. Temperature 4. Displacement
what is 1. vector, 2. scalar, 3. scalar, 4. vector?
300
changing velocity in the negative direction ("slower").
what is deceleration? (negative slope)
300
Name of this diagram:
What is a ticker tape diagram?
300
This device: (also explain how is it used)
What is a calculator? They're good for calculating stuff in physics. Also you can put games on them and they act like an emulator. Ever played Doom on a TI-83???
300
The guy who invented calculus and made up three laws of motion.
Who is Isaac Newton?
400
The name given to the end result of adding vectors.
What is the resultant vector?
400
acceleration = ? *solve for acceleration
initial velocity = 150 m/s
final velocity = 250 m/s
event took 25 seconds.
what is 4m/s2 ?
400
The slope represents:
What is acceleration?
400
The name of this device: (you must correctly explain how it works)
What is a motion sensor? The device sends out sound waves that spread throughout the room. The sound waves "echo" back to the device. Farther objects take longer for the echo to reach the device when compared to closer objects and the computer registers that distance graphically. Echolocation-bats,dolphins, whales, submarines (sonar).
400
For every action, there is an equal and opposite reaction.
Action/reaction pairs
what is the third law of motion?
500
The thing that Vectors and scalars both represent.
what are physical quantities?
500
time; ? seconds (solve)
initial velocity; 0 m/s
final velocity; 60 m/s
acceleration; 6 m/s2
what is 10 seconds?
500
The displacement on the graph is...
what is zero?
500
The name of this device: (you must correctly explain how it works)
What is photogate? It works by blocking the laser that cuts between the two ends of the device. It measures the time that it takes for the black and clear lines to pass through the device. Can calculate acceleration with it.
500
force is equal to mass times acceleration
F=m*a
what is newton's second law of motion?
