How are velocity and speed different? - Answer Velocity has a direction and speed does not have direction. What quantity is calculated from slope of the displacement versus time graph? - Answer velocity What does upward slope on a displacement versus time graph imply about the velocity. - Answer The velocity is positive What is acceleration? - Answer How quickly you change velocity. What is the area under the velocity time graph? - Answer Displacement What is the y intercept of the velocity time graph? - Answer The initial velocity, (Vo in the formulas) What is the area under the acceleration versus time graph? - Answer The CHANGE in velocity. What is the horizontal acceleration of projectiles? - Answer ZERO What direction controls time in falling body and projectile motion problems? - Answer Vertical direction What do you know about two objects that are launched at different horizontal velocities? - 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? - Answer x=(1/2)at^2 Remember, the word "dropped" implies no initial velocity.
