m/s/s
What is velocity?
the quickness of an object
speed in a specific direction
the location of an object
acceleration
When a car goes around a corner at 20 mph, why do we say it accelerates?
The car is accelerating because of the velocity is constant
Cars always accelerate when they are in motion
The car is accelerating because it's changing direction
The car accelerates because it's going 20 mph
A roller coasters accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. What's the acceleration? a = vf - vi / t
Remember: A = Change in Velocity / time
24 m/s2
16 m/s
18 m/s/s
16 m/s2
A drag racer accelerated from 0 m/s to 200 m/s in 5 s. What was the acceleration? a = vf - vi / t
0 m/s
-40 m/s2
40 m/s2
40 m/s
Acceleration can be classified as _______________.
Choose all that apply.
Speeding up
Traveling at a constant speed
Slowing Down
Changing directions
Near Earth's surface, the gravitational acceleration is
9.0 m/ s2
9.8 m/ s2
9.2 m/ s2
32 m/ s2
What is the velocity of an object that has been falling freely in a vacuum for 2 seconds? v = g x t ; g = 9.8 m/s2
9.8 m/s down
10.1 m/s down
19.6 m/s down
39.2 m/s down
