Motion a change in position
position the location of an object
frame of reference group of objects from which you can measure a position or motion (can move)
speed how fast an object's position changes
velocity measurement that combines speed & direction
acceleration change in velocity over time
mass amount of matter in an object
momentum comparison of mass and velocity (more an object has, the easier to move other objects)
inertia tendency to resist change
Calculation of Speed distance divided by time
Calculation of Velocity direction divided by time
Calculation of Acceleration final velocity - initial velocity divided by time
Calculation of Momentum mass x velocity
Units of Distance kilometer (km) meter (m) decimeter (dm) centimeter (cm) millimeter (mm) micrometre (micron) nanometer (nm) angstrom
Units of Speed miles per hour meters per second kilometers per hour
Units of Acceleration Meters per second squared
Units of Momentum kg x m/s
Why do different frames of reference see things differently? different perspective
How can you be moving in one frame of reference and not in another? ?
Which is harder to move, a bowling ball or baseball? Why? Bowling Ball - heavier. The more mass, the more inertia, the harder it is to move
