There is a gravitational force between you and your desk. This gravitational force is very small because:
The masses are tiny compared to Earth's mass
It doesn’t need to be large
The distance between the objects is small
It is a noncontact force
Mass and weight are different. Mass depends on ____. Weight depends on ____.
Gravitational force, the amount of matter
Placement, force
Force, placement
The amount of matter, gravitational force
Which of the following is most closely related to gravity?
Distance
Mass
Weight
Speed
If the mass of one of two spheres increases, how does it affect the gravity between the two spheres?
The gravity increases
The gravity decreases
The gravity fluctuates
The gravity is not affected
Gravity is an example of which kind of force?
Contact
Noncontact
Speed
Direction
Gravitational force differs based on two things. It increases with increasing ____. It decreases with increasing ____.
Mass
Distance
Describe the difference between contact and noncontact forces.
An object’s weight is ____ its mass.
Equal to
Less than
Proportional to
Not related to
A planet is discovered that has twice the mass of Earth but the same gravitational acceleration. If you weigh 700 N on Earth, on the new planet you would weigh:
350 N
700 N
1,400 N
2,800 N
Mass varies depending on where the object is located.
True
False
Describe how the models represent a gravitational force as an attractive force. (To build your answer, you can use the following senteces that explain the model in the picture. 1. Gravitational force always acts as a pull between two objects, bringing them closer together.
2. The models show that as the mass of an object increases, the gravitational pull between the two objects also increases.
3. For example, if the mass of one object doubles, the force of gravity doubles as well (refer to Model 2).
4. The gravitational force is never a push; it always pulls objects together, regardless of their size or distance.)
Make a claim about the effect of mass on the gravitational force between objects. Support your claim with evidence from the models.
(To build your answer, you can use the following sentences/ideas.
1.The mass of an object directly affects the strength of the gravitational force it exerts.
2. As shown in the models, doubling the mass of one object doubles the gravitational force between the objects.
3. When both objects have their masses doubled, the gravitational force increases even more—four times stronger, as seen in Model 3.
4.This shows that gravitational force depends on the product of the two masses and proves that mass is a key factor in determining gravitational pull.)
