Go to phet. colorade. edu/simulation
Select Physics on the sidebor, then select Gravity Force Lab
When the simulation first starts, the objects the humanoids are holding are 38 kg for the blusone
and 25 ko for the red one. On your paper, write the force in Newtons expressed as CETTE
notation (for example, 0.0035 is written os 3.5 X 10').
Question
a) What is the size of the force of the red object on the blue object?
b) What is the size of the force of the blue object on the red object?
alculate the acceleration due to gr
on the next page.
Increase the size of the red object until it equals the blue object.

Question 2
a) What is the size of the force of the red object on the blue object?
b) What is the size of the force of the blue object on the red object?
Decrease the size of the red object until it is the mass of the blue object.
Question 3:
a) What is the size of the force of the red object on the blue object?
b) What is the size of the force of the blue object on the red object?
•
Try changing the mass of the objects in relation to each other. Observe the force on each object.
Question 4:
What general rule can you write to explain the forces between objects of different mass?
If the moon were twice as massive as it is (it is about 1/6 the mass of the Earth), how would that
change the gravitational pull on the Earth?
Increase the blue object's mass to 50 kg, and the red object's mass to 30 kg. Now, move the
humanoid holding the red object closer to the blue object.
