Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Consider speed Was the ball moving at a constant speed or was it changing speed? How could you tell? Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Step 1

Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Focus question What made the ball fall when the student let it go? Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Step 2

Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Focus question What is gravity? Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Step 2

Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Focus question Gravity exerts a force that, in this case, is responsible for making objects fall. What is a force? Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Step 2

Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Focus question What questions could you ask to analyze the motion of the falling ball? Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Step 2

Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Discuss speed What information do we need to calculate an object’s speed? Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Step 7

Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Remember These? t (s) = time x (cm) = position Δt (s) = change in time Δx (cm) = change in position v (cm/s) = speed Δv (cm/s) = change in speed a (cm/s2) = acceleration a (m/s2) = acceleration Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity Step 9
