When adding Vectors, this is the graphical method you should use.

What is tip to tail?

100

The horizontal acceleration of a projectile

What is zero?

100
This is the shape of the path of all projectiles.
What is parabolic?
100
What is the initial vertical velocity of a horizontal projectile?
What is 0?
100

In the hunter monkey demo, the hunter should aim here.

What is at the monkey?

200

How do you symbolize the range of a projectile?

What is delta x?

200

The vertical acceleration of a projectile?

What is - 9.8 m/s2?

200

This is the path that a projectile take in the absence of gravity.

A straight line

200

This is the speed of the projectile at the top of it's path.

What is only horizontal speed?  (Vertical speed is zero.)

200

This is were a package would land if it was dropped from a plane flying at a constant horizontal velocity.

What is directly under the plane?
300

Displacement refers to how far out of place an object is and it is the object's overall change in position. Is displacement a vector or scalar quantity?

What is vector?

300

This happens to the vertical speed of a projectile on the way up.

What is slows down?

300
This is the only force that acts on a projectile.
What is gravity?
300

Because motion in the x-direction and the y-direction are independent of one another, the amount of time a projectile is in the air depends on its _________ velocity.

What is vertical?

300

For the ballistic car demo, this is where the ball landed.

What is in the cart?

400

If a person is running at a rate of 5mph North, is this a vector or scalar quantity?

What is vector?

400

This happens to the vertical speed of a projectile on the way down.

What is speeds up?

400

Which of these is NOT a projectile?  a) throwing a stone on a lake. b) tossing a baseball to second base. c) an airplane landing

c) an airplane landing

400

For a ball that’s shot at an angle, explain what happens to the vertical component of the initial velocity and of the acceleration throughout the flight.

What is velocity decreases (from positive to zero to negative and more negative). Acceleration remains the same.

400

This is the ONLY thing that X and Y values share in projectile motion as shown by the Steel Ball demo.

What is time?

500

This velocity is constant throughout the projectile's path.

What is horizontal velocity?

500

The acceleration of a projectile at the top of it's path?

What is -9.8 m/s2?

500

X and Y values are _____________ of each other in projectile motion.

What is independant?

500
A baseball is thrown horizontally off of a cliff with an initial velocity of 80 m/s. A bowling ball is dropped from the same cliff at the same time. Which hits the ground first?
What is both?
500

For this demo, the ball was in the car and was launched vertically while the cart was moving horizontally.  This is the special name of this type of car.

What a ballistic car?
