To help explain how two bodies that are not in contact can exert a force on one another (i.e. gravitational, magnetic or electrostatic) we use the concept of fields.
Gravitational fields are defined as:
Fields are spheres of influence. They are invisible and intangible; they simply demonstrate how strong a characteristic is at a certain distance. Consider a campfire. We can think of it as having a heat field.
The _________ we get to the fire, the stronger the field becomes.
Notice that its units are in…
Likewise, the __________ the fire is, stronger the field.
Ex 1: The Earth is not actually a perfect sphere. Just like a spinning basketball, it is an oblate spheroid … or kinda bulgy in the middle. Calculate the acceleration due to gravity: a) At the North Pole (r = 6.370x106 m)
b) At the Equator (r = 6.386x106 m)
Ex 2: The moon is 385 000 km away from the Earth’s surface. What is the Earth’s gravitational field strength at this distance?
