AP Physics 1
What two entities comprise a vector? - correct answer ✔Magnitude and
direction
What do you do with any vector that is not on either the x or y axis? - correct
answer ✔Break it up into x and y components using trig, add up the
components.
How are velocity and speed different? - correct answer ✔Velocity has a
direction and speed does not have direction.
What quantity is calculated from slope of the displacement versus time graph?
- correct answer ✔velocity
What does upward slope on a displacement versus time graph imply about
the velocity. - correct answer ✔The velocity is positive
What is acceleration? - correct answer ✔How quickly you change velocity.
What is the area under the velocity time graph? - correct answer
✔Displacement
What is the y intercept of the velocity time graph? - correct answer ✔The
initial velocity, (Vo in the formulas)
What is the area under the acceleration versus time graph? - correct answer
✔The CHANGE in velocity.
, What is the horizontal acceleration of projectiles? - correct answer ✔ZERO
What direction controls time in falling body and projectile motion problems? -
correct answer ✔Vertical direction
What do you know about two objects that are launched at different horizontal
velocities? - correct answer ✔They fall, vertically, the by the same amount in
the same time.
What equation describes the distance that a dropped object falls "t" seconds
after it started moving? - correct answer ✔x=(1/2)at^2 Remember, the word
"dropped" implies no initial velocity.
What equation describes the distance that a horizontally launched projectile
falls t seconds after it started moving? - correct answer
✔x=(1/2)at^2 ...Horizontal velocity does not affect the time of fall.
What equation describes the speed of a dropped object "t" seconds after it
started moving? - correct answer ✔V=Vo + at ...The word "dropped" means
no initial velocity.
What equation describes the speed in the x-direction of a projectile "t"
seconds after it started moving? - correct answer ✔Vx=(Vxo)t ...Recall that
there is no acceleration in the horizontal direction.
What equation describes the speed in the y-direction of a projectile "t"
seconds after it started moving? - correct answer ✔Vy=Vyo + gt ...Watch the
signs.
