16 Section 1: Describing Motion When is an object in motion? What is the difference between distance and displacement?
17 - Describing Motion Whether or not an object is in motion depends on the reference point you choose. Relative Motion
18 Distance and Displacement Distance is the total length of the actual path between two points. Displacement is the length and direction of a straight line between starting and ending points.
19 End of Section: Describing Motion
20 Section 2: Speed and Velocity When is an object in motion? What is the difference between distance and displacement?
21 Calculating Speed If you know the distance an object travels in a certain amount of time, you can calculate the speed of the object.
22 Graphing Motion You can use distance-versus-time graphs to interpret motion.

25 End of Section: Speed and Velocity
26 Section 3: Acceleration What kind of motion does acceleration refer to? How do you calculate acceleration? What graphs can be used to analyze the motion of an accelerating object?
27 Calculating Acceleration To determine the acceleration of an object, you must calculate its change in velocity per unit of time.
28 Calculating Acceleration As a roller-coaster car starts down a slope, its velocity is 4 m/s. But 3 seconds later, its velocity is 22 m/s in the same direction. What is its acceleration? Read and Understand What information have you been given? Initial velocity = 4 m/s Final velocity = 22 m/s Time = 3 s
29 Calculating Acceleration As a roller-coaster car starts down a slope, its velocity is 4 m/s. But 3 seconds later, its velocity is 22 m/s in the same direction. What is its acceleration? Plan and Solve What quantity are you trying to calculate? The acceleration of the roller-coaster car = What formula contains the given quantities and the unknown quantity? Acceleration = (Final velocity - Initial velocity)/time Perform the calculation. Acceleration = (22 m/s - 4 m/s)/3 s = 18 m/s/3 s Acceleration = 6 m/s 2 The acceleration is 6 m/s 2 down the slope.
30 Calculating Acceleration As a roller-coaster car starts down a slope, its velocity is 4 m/s. But 3 seconds later, its velocity is 22 m/s in the same direction. What is its acceleration? Look Back and Check Does your answer make sense? The answer is reasonable. If the car s velocity increases by 6 m/s each second, its velocity will be 10 m/s after 1 second, 16 m/s after 2 seconds, and 22 m/s after 3 seconds.
31 Calculating Acceleration Practice Problem A falling raindrop accelerates from 10 m/s to 30 m/s in 2 seconds. What is the raindrop s acceleration? (30 m/s - 10 m/s) 2 seconds = 10 m/s 2
32 Calculating Acceleration Practice Problem A certain car can accelerate from rest to 27 m/s in 9 seconds. Find the car s acceleration. (27 m/s - 0 m/s) 9 s = 27 m/s 9 s = 3 m/s 2
33 Graphing Acceleration You can use both a speed-versus-time graph and a distanceversus-time graph to analyze the motion of an accelerating object.

35 End of Section: Acceleration
36 Section 4: Energy What factors affect an object s kinetic energy and potential energy? How can kinetic energy and potential energy be transformed? What is the law of conservation of energy?
37 Exponents An exponent tells how many times a number is used as a factor. For example, 3 x 3 can be written as 3 2. You read this number as three squared. In the formula for kinetic energy, speed is squared. For example, you can calculate the kinetic energy of a 70-kg person moving at a speed of 2 m/s by using the formula below. KE = ½ x Mass x Speed 2 = ½ x 70 kg x (2 m/s) 2 = 140 kg m 2 /s 2 or 140 joules. Note: 1 kg m 2 /s 2 = 1 joule
38 Practice Problem Exponents What is the kinetic energy of a 30-kg rock moving at a speed of 10 m/s? 1,500 joules
39 Kinetic Energy Kinetic energy increases as mass and speed increase.
40 Potential Energy Gravitational potential energy increases as weight and height increase.
41 Transformations Between Potential and Kinetic Energy A pendulum continuously transforms energy from kinetic to potential energy and back.
