Description:

Students will perform a simple lab involving the use of a spring scale and various masses to determine the strength of the gravitational field strength at the surface of the earth (9.8N/Kg). The influence of varying mass on the strength of gravitational forces is explored as one step toward the ultimate goal of constructing Newton’s Law of Universal Gravitation. Follow up activities will provide the opportunity to explore the exact influence of distance on gravitational forces and to calculate the value of the Gravitational Constant, G.
