Section 1 summary
Section 1 Summary

  • A reference point is an object that appears to stay in place.

  • The Earths surface is a common

    reference point for

    determining motion.


Section 1 summary1
Section 1 Summary

  • Speed is a measure of how fast something is moving.

  • Average Speed = total distance/total time.

  • The speed at any instant is called “instantaneous speed”.


Answers
Answers:

  • 1. 2 m/s

  • 2. 5km/h

  • 360 km/hr

  • Velocity is the speed of an object in a particular motion.




Practice problems
Practice Problems

  • On a separate piece of paper: vf=final velocity, vi = starting velocity.

  • Find the average acceleration for

  • A)vf = 23, vs = stopped, time=36 sec.

    B)vf= 85, vs = 5 m/s, time = 40 sec

    C) vf = 29, vs =2 m/s, time = 9 seconds

    D) vf = 13, vs = 3 m/s, time = 2 seconds


Section 2
Section 2

  • A force is a push or pull exerted on an object.

  • What does “Exerted” mean?

  • How do I determine the “net force”?


Answer questions
Answer & Questions

  • “Exerted” means to put on to.

  • Net = add all forces acting on the object.

  • Are the forces on a soccer ball balanced or unbalanced? How do you know?


Soccer ball answer
Soccer Ball Answer

  • Unbalanced, because the ball changes speed and/or direction.
