Pendulums

1. What is your personal experience with swinging on a trapeze?
I have no experience with a trapeze, but I used to be in gymnastics where we would swing on bar poles. I was not very good.

2. What applications to "real life" do swinging objects have?
They all experience gravitational forces.

3. What is your prediction about what will happen if two people are on on trapeze and only one is on the other and one switches to the other pole? Explain in terms of mass.
The swinging allows the mass to be distributed from one pole to another.

4. What understanding or ideas do you have about science of back and forth swinging objects. All I can think of is the idea of gravitational force.

Pendulum- mass hanging from a pivot point.
Predictions :
P
1:10 swings
2:5
3:2
4:1

Exploration: does a shorter string and heavier weights minimize the number of swings?
No it does not.
Swinging mass is so interesting!


Quiz: My Experience:
The experience would be consistent. The person on the swing would have consistent amounts of sings back and forth throughout a time period. No matter how hard the person pushes off, the swings


Scratch that: the swinging experience would be crooked

  1. I think you are on to something with the gravity idea!
