Motion and Force A. Motion 1. Motion is a change in position 2. Reference points are necessary
B. Speed 1. The rate of change in position 2. Types of speed: a. Instantaneous b. Constant c. Average 3. Speed = Distance / Time
5. Displacement vs. distancea. Distance – how far something moves b. Displacement – the distance and direction of an object’s change in position from its starting point
C. Velocity 1. Speed in a defined direction 2. Velocity can change even if speed is constant as long as direction changes
D. Acceleration 1. The rate of change of velocity 2. a = (vf – vi) / t or a = v / t 3. Units are m/s/s 4. +a = speeding up; -a = slowing down
Example: constant speed & acceleration
Motion. The process of changing position. Distance The total length of your path.
Motion, Acceleration, and Forces (chapter 3) Motion occurs as something changes position ◦ Relative motion appears according to your position ◦ Distance.

Motion graphs 1.Position (displacement) vs. time 2.Distance vs. time 3.Speed vs. times 4.Velocity vs. time 5.Acceleration vs. time ________.
A graph of the instantaneous velocity of an object over a specified period of time Time is independent (x-axis) Velocity is dependent (y-axis) Remember,
An object is in motion if the distance from another object is changing. A reference point is the starting point you choose to describe the location,
Motion in One Dimension. Displacement x = x f - x i.
Displacement vs Time, Velocity vs Time, and Acceleration vs Time Graphs.
Speed and Acceleration. Motion Motion occurs when an object changes position relative to a reference point You do not need to see an object in motion.
Acceleration in Graphs 9/27/2011. Position vs. Time Graph For this graph, where is the velocity positive? Where is the velocity zero? Where is the velocity.
