This is part of the HSC Physics syllabus Module 5: Advanced Mechanics.
Newton’s law of gravitation, states that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.
So let’s learn to apply Newton’s law of gravitation to:
- Investigate the factors that affect the gravitational field strength
Gravitational Field follows this equation:
g = \frac{GM} {r^2}- g is the gravitational field strength
- G is the gravitational constant
- M is the mass of the plant
- r is the radius
Gravitational field strength is
- Proportional to the mass of the orbital body.
- Inversely proportional to the radius squared
Gravitational field strength
