Gravity Force Lab (AP Physics)
In this experiment, you will use a simulation to measure the gravitation force between two masses. You’ll determine how the strength of the force of gravity depends on the two masses and the distance between them. You’ll also determine a value for the Universal Gravitation constant, G.

Learning Objectives aligned with the (Science Practices)
The students will be able to:
- 1.C.3.1 design a plan for collecting data to measure gravitational mass and to measure inertial mass and to distinguish between the two experiments. (4.2)
- 2.B.1.1 apply F = mg to calculate the gravitational force on an object with mass m in a gravitational eld of strength g in the context of the effects of a net force on objects and systems. (2.2, 7.2)
- 2.B.2.1:apply g=GM/r^2 to calculate the gravitational field due to an object with mass M, where the field is a vector directed towards the center of the object of mass M (2.2)
- 2.B.2.2 approximate a numbers all value of the gravitational field (g) near the surface of an object from its radius and mass relative to those of the Earth or other reference objects. (2.2)
- 3.C.1.1 use Newton’s law of gravitation to calculate the gravitational force the two objects exert on each other and use that force in contexts other than orbital motion. (2.2)
- 3.C.1.2 use Newton’s law of gravitation to calculate the gravitational force between two objects and use that force in contexts involving orbital motion. (2.2)
- 3.G.1.1 articulate situations when the gravitational force is the dominant force and when the electromagnetic, weak, and strong forces can be ignored. (7.1)
