Newton's Laws of Gravitation Flashcards
1
Q
What is gravitational force?
A
Gravitational force is the attractive force between two objects with a mass.
2
Q
What is the gravitational field?
A
The gravitational field is the region of space surrounding a body in which another body experiences a force of gravitational attraction.
3
Q
What is inertial mass?
A
Inertial mass measures the resistance of a body to forces imposed on it.
4
Q
What is the formula for gravitational force between two objects?
A
Fg = (Gravitational constant x mass1 x mass2)/ radius^2
Fg = Gm1m2/r^2
5
Q
What is the gravitational constant?
A
6.67 x 10^-11
6
Q
How to calculate the gravitational field strength of Earth?
A
gfs = Gm1/r^2, using mass of Earth, and the radius of Earth
