Position
A coordinate system used to describe the motion of an object
Frame of Reference
What is the distance traveled in a certain amount of time?
Speed
Any quantity that consists of a a magnitude, or size, only
Scaler
Under what conditions is momentum conserved?
In an isolated system
What is the acceleration for objects in free fall?
9.81 m/s2
This tells you how far you've traveled
Distance
Velocity involves what two things
Speed and direction
Vector consists of what two things
The motion of objects that fall due to gravity alone with no other forces acting on them is called what?
Free fall
Acceleration occurs when one of these things happen
Change in speed, Change in direction, or when both speed and direction change
This is dependent only on your starting position and your ending position
Displacement
How long will it take you to travel 647m if you travel at 47.2 m/s
13.7s
Name three scaler quantities
Temperature, pressure, speed, distance
The type of motion you experience when moving along a circular path.
Circular motion
Why do wee continue to use Newton's mechanics for motion?
The are workable without being overly complex
Starting from point a (10m east) and moving to B at (40m east), then moving west to point C at (20m east) what is our total distance? What is our total displacment?
Distance = 50m
Displacement = 10 m
A boat is cruising north at 15 kph. The tide is moving 5 kph south what is the total vector?
10kph
Name three vector quantities
Displacement, velocity, acceleration, force, momentum,
Acceleration toward the center of a circular path
Centripetal Acceleration
While standing along the train tracks, you see a woman walking through the cabin of the moving train car. What is her frame of reference? What is yours?
Woman - train car
you - ground
What formula do you use to find the displacement of a two-dimensional movement?
Pythagorean theorem
What two factors affect momentum?
Mass and velocity
What is simply defined as the size, distance, or quantity of something in physical science?
Magnitude
