Kinematics
When the equation vf2 = vi2 + 2ad is valid to use.
What is a problem with constant acceleration?
An object moving only under the influence of gravity.
What is free fall?
The two types of reference frames.
What are inertial and non-inertial?
mv2/r
What is centripetal force?
If an object C moves relative to reference frame A with a velocity v1 and reference frame A moves with velocity v2 relative to frame B, then the object with respect to frame B moves with:
vc = v1 + v2
What is a Galilean transformation of velocity?
While driving down a highway at night going 20 m/s, a deer steps in the road 35m ahead of you. Your reaction time before stepping on the brakes is 0.5s, and the deceleration of your car is 10 m/s2.
Your distance to the deer when you've come to a stop.
What is 5 meters?
A ball is thrown horizontally at 25 m/s and travels x = 50m before hitting the ground.
This is the height from which it was thrown.
What is y = 19.6 m?
Susan is driving north at 60mph and Trent is driving east at 45 mph; they are both approaching an intersection.
This is Trent's speed relative to Susan's reference frame.
What is 75 mph south of east?
A satellite orbiting the moon very near the surface has a period of 110 minutes. Take the radius of the moon as r = 1.74*106 m.
This is its free fall acceleration.
What is a = 1.58 m/s2?
Carin's favorite color.
What is rose pink?
A stunt man drives a car at a constant speed of 20 m/s off a 30m tall cliff. The road leading to the cliff is inclined upward at an angle of 20°.
This is the distance from the base of the cliff that the car lands.
What is 61.4 meters?
A supply plane needs to drop a package of food to scientists working on a glacier. The plane flies 100 m above the glacier at a speed of 150 m/s.
This is how far short of the target the pilots should drop the package.
What is 678 meters?
I am with my friend riding in the back seat of a car that is going 65 mph.
This is my friend's velocity relative to my frame of reference.
What is 0 mph?
ω2r
What is radial acceleration?
The first Egyptian pharaoh to suggest belief in only one god.
Who is Akhenaten?
A stunt man drives a car at a constant speed of 20 m/s off a 30m tall cliff. The road leading to the cliff is inclined upward at an angle of 20°.
This is the car's impact speed.
What is 31.4 m/s ?
A rifle is aimed horizontally at a target 50m away. The bullet hits the target 2.0cm below the aim point.
This was the bullet's flight time.
What is 0.064 seconds?
A model rocket is launched with an upward acceleration of 6 m/s2 and, from an unexpected gust of wind, a horizontal acceleration of 1.5 m/s2. How far is the rocket from its launch point 6 seconds later, when the gust subsides and the rocket is out of fuel?
What is 111m?
A high speed drill rotating counterclockwise at 2400 rpm comes to a halt in 2.5 seconds.
This how many revolutions it makes as it stops.
What is 50 revolutions?
What is 1869?
