WATERFALL BY: MISAKI A., TERESA C., EMILY L., SELINA M.
Length of the ride: 1.2 KM Time of ride: 1.42 min Height of drop: 12.19 m INFO
What is the velocity of the log before it it’s the water? PART A
What is the deceleration after the log ride hits the water? (it takes 4.5m to slow down to 3m/s) PART B
What is the force of the water? (m-212kg) PART C
Find the average velocity of the ride. (m/s) PART D 1
Find the average speed of the ride. (m/s) PART D 2
PE1+KE1=PE2+KE2 mg(12.19)=1/2mv2 12.19(9.8)=1/2v2 238.924=v2 15.5m/s=v Velocity is 15.5 m/s ANSWER A
V2=v2+2ad (3.0)2=(15.5)2+2a(4.5) 9=240.25+9a a=-25.694m/s2 a=-26m/s2 ANSWER B
F=ma F=(212)(25.694) F=5447.2 N Fwater= 545oN ANSWER C
V=d/t d = 0 because it starts and finish at the same point T=1.42 min -> 201 s V=0/201 Average velocity = 0m/s ANSWER D1
V=d/t d= 1.2km -> 12.00m T= 1.42min -> 201s V=1200/201 Average speed = 6.0 m/s ANSWER Q D2

Physics Quicky A Stone Thrown Downward
An object is in motion if the distance from another object is changing. A reference point is the starting point you choose to describe the location,
Acceleration. The rate of change in velocity Acceleration The rate of change in velocity Examples…. –Speeding up Positive acceleration –Slowing down.
1. What distance will a train stop in if its initial velocity is 23 m/s and its acceleration is m/s/s? 1058 m xvivfatxvivfat.
Motion SWBAT define speed and acceleration; relate acceleration to change in speed; calculate distance, speed, and acceleration.
SHMD 239 Kinesiology Unit 5. In the triathlon race, the time taken for the winner to complete the race was: Work out the average velocity for the different.
Acceleration a change in velocity ( speed or direction or both ) over time –speeding up or slowing down –changing direction moving in a circle is always.
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.
Forces : Velocity / time graphs and acceleration.
Acceleration Definition 2 ways to do it Positive acceleration Negative acceleration (deceleration) A change in velocity Change speed and/or Change direction.
Acceleration. Acceleration is a vector quantity. When the speed of an object changes, it is accelerating. Acceleration demonstrates the change in speed.
Velocity vs. Time Analysis of a Velocity vs. Time graph.

Instructions for using this template. Remember this is Jeopardy, so where I have written “Answer” this is the prompt the students will see, and where.
Force. a push or a pull a force gives energy to an object causing it to… –start moving, stop moving, or change direction the unit of measurement is Newtons.
Motion and Force A. Motion 1. Motion is a change in position
= constant speed forward = no speed, stopped = constant speed; negative direction Time (s) Distance mDistance m.
Distance V Displacement DISTANCE: The length of a path between two points DISPLACEMENT: Direction from a starting point and the length of a straight line.
