Presentation Transcript

  1. Quiz Review The good students will take copious notes.

  2. The Topics You Need To Study • Unit Conversions • One dimensional Motion • Solving for distance • Solving for time • Solving for velocity • Solving for acceleration • Vectors • Finding magnitude

  3. Unit Conversions • DO NOT WRITE MPH!!! Instead, write miles/hr (this will help you keep from getting confused) • 1600 meters = 1 Mile • 1.6 km = 1 Mile • 3600 Seconds = 1 hr

  4. Unit Conversions cont’d • Remember, when converting units, each section of the picket fence (after the first) must be an equivalency (i.e. 1 mile/1600 m, or 1 hr/3600 sec) • Put the unit you want to cancel OPPOSITE (numerator or denominator) • Example: 25 miles 1600 meters 1 hr 1 hr 3600 sec 1 mile

  5. Distance, Time and Velocity USE THE TRIANGLE! How do we find D? How do we find V? D How do we find T? V T Remember: D = VXT is basically one equation!!

  6. Velocity, Acceleration and Time USE THE TRIANGLE! How do we find V? How do we find A? V How do we find T? A T Remember: V = A X T is basically one equation!!

  7. Strategies • Identify what the question is asking for – look for phrases like • How long…? (answer should be a time in sec or min or hours) • How far…? (answer should be distance in meters or km or miles) • How fast…? (answer should be speed/velocity in m/s or km/h or miles/hr) • What is the acceleration of…? (answer should be an acceleration in m/s2)

  8. Write down known info • Distance = ? • Time = ? • Acceleration = ? • Velocity = ? • “Starts from rest…” → Vi = 0

  9. Identify the completely missing quantity • This will help you identify which of the four basic equations you need. • V = D/T • A = V/T

  10. Vector Stuff • Remember: find the magnitude (length) of a vector by Pythagorean Theorem • Pythagorean Theorem : A2 + B2 = C2

  11. Dr. Mason’s Helpful Hints • Remember your units • Understand the difference between velocity and acceleration • Likewise, understand the difference between m/s and m/s2 • Remember: Δanything = final - initial • Beware of writing units we have NEVER used in class. Examples: miles/hour2, m/s3 • Remember what negative acceleration means

  12. Lest we forget… • There is gravity on the moon. Accept it and move on.
