Study Notes
Gravitational Force
- The strength of the gravitational force between two objects is determined by the mass of the objects and the distance between them.
- The gravitational force is responsible for the attraction between objects with mass.
Effect of Distance on Gravitational Force
- When the distance between two objects increases, the gravitational force between them decreases.
Calculating Gravitational Force
- The formula to calculate the gravitational force between two objects is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them.
Gravitational Constant
- The value of the gravitational constant (G) is 6.67408e-11 N m^2 kg^-2.
Newton's Theory of Gravity
- Isaac Newton proposed the Law of Universal Gravitation to explain the gravitational force between objects, stating that every point mass attracts every other point mass by a force acting along the line intersecting both points.
