Students predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.

In this reading comprehension activity, students read a story called The Death Car. Students answer 10 multiple choice questions about the story. Note: The story contains references to murder and has a gruesome ending.

Centripetal motion can be a complex topic so use this website to review the key concepts, equations, and skills for centripetal motion. Also, the connection to centripetal acceleration is discussed here.

Demonstration showing how individual or multiple objects fall at the same rate.

Acceleration, an increase in the rate of change, is occurring both in the Universe and in human culture on planet Earth. This article explains these fascinating changes.

This lesson will introduce the concept of acceleration, explaining the difference between acceleration and deceleration. It is 10 of 10 in the series titled "Acceleration."

This lesson will introduce the concept of acceleration, explaining the difference between acceleration and deceleration. It is 9 of 10 in the series titled "Acceleration."

Learn more about finding acceleration through the practices found in this lesson. "The process of determining the acceleration of an object demands that the mass and the net force are known." Check out this comprehensive site.
