Rolling Around
The rate of change of distance.
What is speed?
9.8 m/s2 down.
What is g?
This is the shape an object makes when launched as a projectile.
This is the shape of the velocity vs time graph at constant velocity.
What is flat (horizontal)?
What is 510?
What is 10 meters?
The vertical velocity of a free-falling object at its maximum height.
What is 0?
The kind of motion you see if you look at a projectile from a birds-eye view.
What is constant velocity?
The sign of acceleration when the position versus time graph is quadratic and concave down.
What is negative?
This is what Mr. Makmur studied in college.
What is astrophysics/astronomy?
The acceleration of an object at constant velocity.
What is 0?
The amount of acceleration a rocket undergoes when blasting off to 1000 m/s over 20 seconds.
What is 50 m/s2?
This is the angle you want to use if you want to launch something as far as possible.
What is 45o?
DAILY DOUBLE
The shape of the velocity graph when the change in acceleration (jerk) is negative.
What is concave down?
Despite being one of the most famous playwrights in all of history, some conspiracy theorists believe he did not actually exist.
Who is William Shakespeare?
The time in minutes it takes Jimmy, biking at 15 miles per hour, to travel 3 miles.
What is 12 minutes?
The directions of velocity and acceleration when a thrown ball is rising.
What is opposite?
This is the vertical velocity of an object launched at 100 km/s at an angle of 30 degrees above the ground.
What is 50 km/s?
The slope of the velocity versus time graph when acceleration is negative.
What is a negative slope?
This president was known for being both a war hero and a trust-buster. His environmental conservation work also resulted in him being honored by something quite cuddly!
Who is Teddy Roosevelt?
The speed of sound is about 340 meters per second. About how long does it take a clap of thunder to travel one kilometer?
Estimate.
What is 3 seconds?
(t = 2.94 s)
Given a deceleration rate of 10 m/s2, this is how far a driver going 20 m/s (about 45 mph) travels in 2 seconds of braking.
What is 20 meters?
DAILY DOUBLE
The time it takes for an object launched horizontally from a height h to reach the ground.
What is √(-2h/g)?
The slope of the position versus time graph when velocity is positive and acceleration is negative.
What is positive?
This celestial object generated lots of controversy when it was (rightly) demoted to a dwarf planet.
What is Pluto?
