Key Questions and Terms:
Why do scientists need creativity?
Scientists need creativity because they have to think up solutions to any problems that come their way.
What is gravity?
Gravity is a force that can be used by anything with mass can utilize.
Why are two objects with mass drawn to each other?
Because one is bigger and they are close enough that the gravitational pull of one outdoes the other and draws it close to it's center of gravity
List the two things that affect gravitational force.
Mass, and distance
How are mass and weight different?
Mass refers to the amount of matter in an object but weight is the force experienced by an object due to gravity
Why does weight change depending on location?
Weight is the force of gravity on an object, the weight of an object increases in a location with more gravity and decreases in a place with less.
Explain in your own words the law of universal gravitation
Any two objects with mass have gravity, the bigger the two objects are, the more gravity they'll have between them, and the closer they are, the more gravity they'll have between them. The farther they are, or smaller they are, the less gravitational pull they'll have together.
Why does gravitational force vary between objects?
These two objects might be small, or be very far apart, and the more that varies, the more the amount of gravity will vary.
How do we know how much gravitational force objects have?
You have to take into account the combined masses, and you have to think about how far apart the two objects are. With that, you have the perfect algorithm for measuring gravitational force.
How does distance affect gravity?
The greater the distance, the less gravitational pull. The smaller the distance, the more gravitational pull.
