Stupendous Speed
What is the formula for velocity?
Velocity = displacement / Time
What formula would we use if we wanted to find out how an object's velocity changed within a certain period of time?
What is Acceleration
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
Which of our formulas must have a direction in order to be complete?
veloctiy or Acceleration
What is the average speed of a cow that walks east 60 meters in 90 seconds?
0.7 m/s
A horse runs for 4 minutes south at 5 m/s. how far the horse goes from its origional position?
20 m south
A motor cycle reaches a Velocity of 60 m/s south. After 5 seconds the motor cycle changed the velocity to 50 m/s south. What is the acceleration of the motor cycle?
-2 m/s squared, south
describe the motion during part A of the graph
Part A shows a positive and constant acceleration. the object is speeding up uniformly
A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled?
40 meters
A cyclist in a marathon travels 10 km east at 5 m/s. how long (in minutes) it takes him to reach the finish line?
33.33 min
How would you describe negative acceleration? You must use the word "velocity".
decrease in velocity over time
describe the motion during part B of the graph
Part B shows a zero acceleration. the object is moving with a constant velocity
What is the distnance of an object moving east for 6 seconds at 105.3 m/s?
631.8 m
A pink alien moved south in it's spacecraft 2 km at a rate of 20 m/s. How much time did it take him to do this in seconds?
100s
Mr. Conley's truck goes straight from a red light signal and reaches 70m/s within 5 seconds. What is the acceleration of Mr. Conley's truck?
14 m/s every second, straight
which part of the graph shows a higher acceleration?why
C, because the slope is higher at part C
