Summary Students learn what a pendulum is and how it works in the context of amusement park rides. Listen to the tick-tock on the clock and see if it is nice, even tick-tock. Again, whatever the pendulum is attached to is going to have some friction that slows it down. Do mass or initial angle affect the period of the pendulum? Has anyone ever tried this with one of those table top vacuum simulators? That's going to get tedious quite quickly, so what about automating things? Think of it this way:
Tie one end of both strings to the meter stick, toward the middle of the stick. There is Mechanical Energy. Will a pendulum swing on the moon? Often used to regulate devices, such as clocks. Would such a pendulum keep swinging forever inside a vacuum?
Tie a tennis ball or other soft ball or weight to the ceiling of the classroom, and use it to demonstrate the following pendulum scenarios to the students. But perhaps a physicist could elaborate on this vacuum scenario - as I am unaware of any other forces which slow down pendulums other then air resistance and friction. Most of the friction will be at the pivot point, but there will be a bit of air resistance too. Earth and Planetary Sciences.
Key concepts Physics Gravity Motion Pendulums Introduction Did you know that playground swings can provide a good lesson in physics—as well as lots of fun? Lift the left side of the clock slightly. But that still won't work because the weight is going to accelerate as it goes down, like any falling object. While exploring the physics of pendulums, they are also introduced to Newton's first law of motion — about continuous motion and inertia. Yes No Thanks for your feedback!
