Acceleration How quickly velocity changes.

Acceleration TIME0.00 s1.00 s2.00 s3.00 s4.00 s VELOCITY0 m/h10 m/h20 m/h30 m/h40 m/h This table is for acceleration from rest What is the velocity of the car? What is it called when velocity changes over time? What is the acceleration of this car?

Acceleration TIME0.00 s1.00 s2.00 s3.00 s4.00 s VELOCITY0 m/h10 m/h20 m/h30 m/h40 m/h

Acceleration We can look at it another way: What if the acceleration of an object is 10 meters/second/second? If it starts at rest, how fast is it moving at the end of each second? Fill in the chart below TIME VELOCITY

Acceleration

Example A car traveling at 25 m/s accelerates at 3.0 m/s/s for 5.0 seconds. How fast is it traveling at the end of the 5.0 seconds?

Acceleration Downwards Galileo collected data concerning falling objects, and observed the following when those objects were dropped near Earth’s surface: Based on Galileo’s data, what is the acceleration due to gravity? TIME0.0 s1.0 s2.0 s3.0 s4.0 s VELOCITY0 m/s

Free-Fall Ignoring air resistance (friction), objects accelerate at m/s/s What if the object is thrown upwards? TIME0.0 s VELOCITY+20 m/s

How fast  How far? Let’s drop an object and see how far it falls as time passes: TIME0.0 s INSTANTANEOUS VELOCITY 0 m/s AVG VELOCITY-- DISTANCE TRAVELED EACH SEC -- TOTAL DISPLACEMENT --

How far during acceleration
