5. 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

6. 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

7. 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

8. 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
