  1. Force and Motion 3.1 Mrs. Chastain Advanced 2017

  2. S8P3a • S8P3. Obtain, evaluate, and communicate information about cause and effect relationships between force, mass, and the motion of objects. • a. Analyze and interpret data to identify patterns in the relationships between speed and distance, and velocity and acceleration. • (Clarification statement: Students should be able to analyze motion graphs, but students should not be expected to calculate velocity or acceleration.)

  3. Learning Target • Students will be able to determine the speed/velocity of an object.

  4. Speed • The speed of an object is the distance the object travels per unit of time. • The rate at which someone or something moves or travels

  5. Average Speed • The speed of most moving objects is not constant. • Speed of an object may change based on the terrain on which it travels. • To calculate average speed, divide the total distance traveled by the total time. • Example of average speed: 45km/3h = 15 km/h

  6. Instantaneous Speed • The Rate at which an object is moving at a given instant in time. • Example: The speedometer of a car reveals information about the instantaneous speed of your car. It shows your speed at a particular instant in time. On the average, your car was moving with a speed of 25 miles per hour.

  8. Constant Speed • Speed that does not change; it stays constant. • https://www.youtube.com/watch?v=_DtDCBHEM1k

  9. Velocity • Speed in a given direction. • The rate at which an object changes its position. • Ex. If you know the velocity of a storm if you know it is moving 25mph eastward.

  10. Velocity Continued • The equation or formula for velocity is similar to speed. To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it.

  11. Acceleration • The rate at which velocity changes. • A change in velocity can involve a change in speed or direction, or both. • In science it refers to increasing speed, decreasing speed, or changing direction.

  12. Force • Using energy to do work. • Examples: Pushing or pulling.

  13. Motion • An object is in motion if its distance from another object is changing. • https://www.youtube.com/watch?v=LEs9J2IQIZY

  14. Distance • A Measurement that refers to "how much ground an object has covered" during its motion.

  15. Mass • The amount of matter in an object.
