Gravitational Forces
Attractive, noncontact forces between objects that have mass are called this.
What is gravitational force?
This is the curved path an object follows around another object in space.
What is an orbit?
This is the amount of matter in an object, measured in kilograms.
What is mass?
These are used to represent gravitational field strength in diagrams.
What are arrows?
These are the two main factors that affect the strength of gravitational forces.
What are mass and distance?
When referring to forces, this word means pulling together.
What is attractive?
This unit is used to measure weight.
What are Newtons?
This is what happens to gravitational field strength as distance increases.
What is that it decreases?
Objects with a ____ mass and ____ distance will have the strongest gravitational force.
What are large and close?
This is a map of a force field that can be used to predict which way gravitational forces will pull an object.
What is a gravitational field?
This is the main difference between mass and weight.
What is mass stays constant, while weight can change?
Arrows with this type of distance show a stronger gravitational field.
What are arrows that are closer together?
Gravity causes objects to do this.
What is fall toward the center of Earth (or the center of the mass)?
This will happen when a 5-pound weight and a 35-pound weight are simultaneously dropped from the same height.
What is they will land at the same time?
This is the reason that you would weigh less on the moon compared to Earth.
What is the moon has less mass and therefore weaker gravitational force?
This is the relationship between an object's mass and its gravitational field.
What is a larger mass creates a stronger gravitational field?
This rate describes how quickly objects accelerate toward Earth's surface.
What is 9.8 m/s2?
This is why a feather falls slower than a hammer on Earth.
What is air resistance?
This is how an object's weight can change without changing its mass.
What is being in a different gravitational field?
This is what gravitational fields can be used to predict.
What are the strength and direction of noncontact forces?
