PRESENTED BY DANIEL LIN Mock Examination !!! 8. Flying Objects
Visualize – In Soviet Russia, guns shoot bullets. v(x), the speed of the bullet as a function of its position in the wall. L, the path length of the bullet within the wall. L
Visualize – Initial Conditions Moment of Entry Speed at Entry Moment of Exit Speed at Exit
Calculations Acceleration function: Separable! Use the initial conditions to find k! MAGIC !
Calculations Two initial conditions: And …
Calculations We now have the velocity function with respect to time… NOT GOOD ENOUGH! We need
More calculations… With every questions that you think you know the answer to. Ken wants you to learn modesty.
More calculations… Ken’s “Hint” Re-Write the original acceleration function: Separable & Solve
Almost done We already know When position x(0) = 0, the velocity is Solve for c MAGIC !
And v(x) is… Plug in the constant: Now we need to find L (The distance traveled during that 0.01 seconds.) We know the bullet exits the wall at
Conclusion Wouldn’t you like to know? That pakalolo plant ready for harvest?
Unit 2- Force and Motion Vocabulary- Part I. Frame of Reference A system of objects that are not moving with respect to each other.
Aim: How can we solve problems dealing with horizontally fired objects? Do Now: An object falls freely for 75 m. How long does it take to reach the ground?
Motion. The process of changing position. Distance The total length of your path.
Speed vs. Time Graphs. What does a Speed v. Time graph show? Shows how the speed (or velocity) of an object is changing over a given period of time.
Section 2.4 Graphs of Motion. Why Use Graphs? Show relationships between distance, velocity, acceleration, and time Visual and clear way of representing.
Average and Constant Acceleration Chapter 2. Acceleration.
Displacement and Distance Aren’t the same thing?.
Insanely Super Important Kinematics Terms. Kinematics The study of the motion of objects- does not deal with the forces that caused the motion.
Velocity and Acceleration. Velocity and Speed Velocity and speed are both how fast you are going, but velocity implies a direction (N, S, E, W) as well.
Starter Vocabulary Term What is distance? What is displacement? What is frame of reference? What is speed? What is velocity? What is acceleration? Definition.
Acceleration & Speed How fast does it go?. Definition of Motion Event that involves a change in the position or location of something.
Review. What is it called when the speed of an objects changes?
What is motion? Motion is the change in the position of an object. To describe the motion of an object we use terms like: Distance, displacement, speed,
Kinematics- Acceleration Chapter 5 (pg ) A Mathematical Model of Motion.
Kinematics Examples 4 A world class sprinter can burst out of the blocks to essentially top speed(of about 11.5 m/s) in the first 15 m of the race. 4 What.
AIM Read a distance versus time graph Calculate velocity.
Motion. 2.1 Investigation: Position, Speed, and Velocity Key Question: How are position, speed, and velocity related? Objectives: Measure positive and.
Chapter 2 Motion Along a Straight Line. Linear motion In this chapter we will consider moving objects: Along a straight line With every portion of an.

Acceleration Velocity-time graph Questions. Acceleration.
Demonstrate an understanding of the difference between scalars and vectors and give common examples Add vectors by graphical representation to determine.
The distance an object travels in a certain amount of time. › Average speed – Total distance divided by total time › Constant speed - Speed that does.
OBJECTIVE: TO DEFINE AND CALCULATE SPEED. DO NOW: WHAT IS THE SPEED OF AN OBJECT THAT IS STANDING STILL?
Motion An object is in motion when it changes it position relative to to reference point.
2-dimentional motion Parabolic or Projectile Motion.
Observed in relation to another object that appears to stay in place (reference point) When an object changes position over time when compared to.
Motion Notes. Key Terms 1)Motion: 2)Reference point: The state in which one object’s distance from another is changing. A place or object used for comparison.
Changing the Phase of a Light Wave. A light wave travels a distance L through a material of refractive index n. By how much has its phase changed?
Because PHYSICS! That’s why! An intro to Kinematics.
How to Calculate Speed and Acceleration. Speed Speed- the distance traveled divided by the time during which the motion occurred. Constant Speed- movement.
Measuring Waves Physics 7(B). Learning Objectives Describe and measure the parts of a wave Explain the relationship between frequency and wavelength Use.
Time Graphs Analyze velocity-time, distance-time, and force-time graphs of sporting activities.
Physics Chapter 3 Describing Motion. 3.1 Picturing Motion Motion diagram Operational definition Particle model 3.2 Where and When Coordinate systems Scalar/Vector.
Circular Motion Centripetal Acceleration. Revisiting Acceleration What is acceleration? Acceleration is how fast an object’s velocity changes. But what.

September 24-25, 2015 So far, we have studied free fall – the vertical (up/down) motion of an object that only experiences force due to gravity. What.
Speed and Velocity Drag racing videohttp://www.youtube.com/watch?v=ryDYYGI1cwg.
Motion SWBAT define speed and acceleration; relate acceleration to change in speed; calculate distance, speed, and acceleration.
A particle moves along the x -axis so that its velocity at time t is given by At time t = 0, the particle is at position x = 1 (a) Find the acceleration.
Kinematics Vocabulary Units and vectors and scalars, oh my!
Mr. Finau Applied Science III. At what points of the flight of an object does it accelerate? How can you tell? During all parts of its flight The.
PHYSICS 50: Lecture 3.1 RICHARD CRAIG. Plan for the day Chapter 3 Free fall in two dimensions Horizontal rifle shot Discussion Baseball hit Relative Velocity.
