ACCELERATION Velocity vs. time graph for an object moving in a straight line. The slope of the blue line connecting points P and Q is defined as the average acceleration in the time interval t= tf- ti.

Average and Instantaneous Acceleration

Quick Quiz 2. 3 Match each velocity vs. time graph to its corresponding acceleration vs. time graph.

ONE-DIMENSIONAL MOTION WITH CONSTANT ACCELERATION When an object moves with constant acceleration, the instantaneous acceleration at any point in a time interval is equal to the value of the average acceleration over the entire time interval

ONE-DIMENSIONAL MOTION WITH CONSTANT ACCELERATION Because the velocity is increasing or decreasing uniformly with time, we can express the average velocity in any time interval as the arithmetic average of the initial velocity v 0 and the final velocity v:

Kinematics Equations

Apply the basic kinematic equations A race car starting from rest accelerates at a constant rate of 5. 0 m/s 2. What is the velocity of the car after it has traveled 30. 5 m?

Apply the basic kinematic equations Problem: A stone is thrown from the top of a building with an initial velocity of 20. 0 m/s straight upward, at an initial height of 50. 0 m above the ground. The stone just misses the edge of the roof on its way down, as shown in figure. Determine (a) the time needed for the stone to reach its maximum height, (b) the maximum height, (c) the time needed for the stone to return to the height from which it was thrown and the velocity of the stone at that instant, (d) the time needed for the stone to reach the ground, and (e) the velocity and position of the stone at t = 5. 0 s.
