Physics Chapters 1.1-1.3 Motion-  The change of an object’s position or orientation with time. Trajectory-  The path along which an object moves, whether it’s straight or curved. Four Types of Motion: - Straight line motion -Circular Motion -Projectile Motion -Rotational Motion Motion Diagram-  A composite image showing an object’s position at several different  equally  spaced instants of time . Operational Definitions-  Concepts are defined in terms of a particular procedure or operation  performed by the investigator. Particle-  An object that can be represented as a mass at a single point in space. ** A particle has no size, no shape, and no distinction between top and bottom or

Unformatted text preview: between front and back. Particle Model- Of motion is a simplification in which we treat a moving object as if all of its mass were concentrated at a single point. Position- Your location at a particular instant in time. Origin- Fixed point of reference, where all distances are to be measured from. Displacement- A change of position. The difference between a final position and an initial position. Uniform Motion- Motion under a constant speed. Speed = (Distance travelled in a given time interval)/(Time interval) Velocity = (Displacement)/(Time interval)...
