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. distance a. Distance – how far something moves b. Displacement – the distance and direction of an objects 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 = (v f – v i ) / t or a = v / t 3. Units are m/s/s 4. +a = speeding up; -a = slowing down
Example: constant speed & acceleration
Ch. 3 & 4 Motion & Forces II. Describing Motion Motion Speed & Velocity Acceleration.
Kinematics: What is velocity and acceleration? Lets Review v = d t Distance traveled (m) Time taken (sec) Average Velocity (m/sec) Instantaneous Velocity:
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,
What is motion? An object is in motion when it’s distance from another object changes. What is a reference point? It is an object or place used to determine.
A change in position relative to some reference point during a period of time. Motion.
Motion Definition: The state in which one object’s distance from another is changing Example 1: (from book) You and book are actually in motion because.
Chapter 2 Notes. Scientific models Used to solve complex questions 3 types Physical model- Something you can physically manipulate The car and ramp are.
Distance vs. Time Analysis of a Distance vs. Time Graph.
Warm Up A particle moves vertically(in inches)along the x-axis according to the position equation x(t) = t 4 – 18t 2 + 7t – 4, where t represents seconds.
Motion Review 8th Grade Force and Motion Investigations 1-4 Summary.
Movement Aim: How can we distinguish between speed, velocity and acceleration?
Chapter 2 Describing Motion: Kinematics in One Dimension.
Section 1 p A change in position Motion occurs when something changes position relative to a point of reference.
Describing Motion with Diagrams. Ticker Tape Diagrams.
Kinematics deals with situations involving motion. S=distance/displacement. If s=0, object is at starting point +- relates to position from a certain.

Position and Motion New and Improved!. What is motion? Motion is when an object changes position. How do you know that the racecar moved? –It changed.
Matter and Motion You know an object is in motion if it is changing position. You know an object is changing position if it moves relative to a reference.
Representing Motion in a Variety of Ways Graphs: - Allows us to interpret motion without even seeing the motion occur What was the object’s velocity (not.
Why do objects keep moving without being pushed or pull? Objects keep moving without being pushed or pulled is the Newton's first law.Another reason an.
Physics Motion, Speed, and Velocity. SC Standards Covered S8P2. Students will be familiar with the forms and transformations of energy. c. Compare and.
What is Motion? Chapter 9 Section 1 and 3. Reference point a place or object used for comparison to determine if something is in motion.
Acceleration - rate of change in velocity per unit time.
Acceleration unit 6.2 year 10. Introduction An often confused quantity, acceleration has a meaning much different than the meaning associated with it.
Chapter 10: Motion 10.1 An object in motion changes position 10.2 Speed measures how fast position changes 10.3 Acceleration measures how fast velocity.
The four kinematic equations which describe an object's motion are: There are a variety of symbols used in the above equations and each symbol has a specific.
