  1. Kinematics-Part II • Velocity: • -Explain how to calculate acceleration from a velocity-time graph. • -Show how to calculate instantaneous velocity and average velocity and show the difference between the two of them. • -Show on a velocity-time graph the following segments for an object moving at: • Constant velocity in the positive direction. • Speeding up in the positive direction. • Moving in the positive direction and slowing down. • Standing still • Moving with a negative velocity. • Acceleration: • Write down the average acceleration equation. • Name three things you could do to accelerate. • Explain how acceleration is different from velocity. Kinematics-Part I • Define the indicate the units for the following: position, distance, displacement, speed, velocity, acceleration, vector, scalar, acceleration due to gravity on Earth • Position: -Explain how to calculate velocity from a position-time graph. -Show how to calculate displacement. -Show how to calculate distance. -Show on a position-time graph the following segments for an object moving at: • Constant velocity in the positive direction. • Speeding up in the positive direction. • Moving in the positive direction and slowing down. • Standing still • Moving with a negative velocity.

  2. Kinematics-Part III • Kinematics Problems: -Write down the kinematics equations for finding change in velocity, acceleration, and time. Solve the following problems using GUIDE: • A ball, which is rolling straight down a hill, has an acceleration of 4 m/s2. If the ball starts from rest, what is the ball’s velocity after 3 seconds? • A glider starts from rest and accelerates for 45 seconds. The final speed of the glider is 103 m/s. Find the average acceleration of the glider. • How long does it take a truck to increase its speed by 20m/s if it has an acceleration of 2m/s2?
