Using Microsoft Excel to Explore Gravity Forces and Accelerations part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a computer lab activity in which students use Microsoft Excel to create a spreadsheet capable of calculating gravity forces and acceleration values for any two objects if the masses of the objects and their separation distance are entered. Students will use their calculators to analyze numerous object pairs and make conclusions about gravity forces and accelerations on earth, on other planets, and in space.

Newton's Second Law: Constant Force Applied to a Skateboarder part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a physics lab in which students generate distance vs. time graphs for skateboarders of different masses being pulled with various values of constant force. Students develop procedures, record and graph data, and analyze the data in light of Newton's 2nd law.
