What two entities comprise a vector? - Answers Magnitude and direction
What do you do with any vector that is not on either the x or y axis? - Answers Break it up into x and y
components using trig, add up the components.
How are velocity and speed different? - Answers Velocity has a direction and speed does not have
direction.
What quantity is calculated from slope of the displacement versus time graph? - Answers velocity
What does upward slope on a displacement versus time graph imply about the velocity. - Answers The
velocity is positive
What is acceleration? - Answers How quickly you change velocity.
What is the area under the velocity time graph? - Answers Displacement
What is the y intercept of the velocity time graph? - Answers The initial velocity, (Vo in the formulas)
What is the area under the acceleration versus time graph? - Answers The CHANGE in velocity.
What is the horizontal acceleration of projectiles? - Answers ZERO
What direction controls time in falling body and projectile motion problems? - Answers Vertical
direction
What do you know about two objects that are launched at different horizontal velocities? - Answers
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? -
Answers 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? - Answers 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? - Answers
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?
- Answers 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?
- Answers Vy=Vyo + gt ...Watch the signs.
What is implied when an object is not accelerating in the x direction? - Answers The body is moving at a
constant velocity
