SHHHHH---CRASH! You have just landed on a new planet. YEAH!!! The first thing you need to do is determine the gravitational acceleration using only a 15 cm string and a pendulum.
A) What equation will you use after you collect your data?
SHHHHH---CRASH! You have just landed on a new planet. YEAH!!! The first thing you need to do is determine the gravitational acceleration using only a 15 cm string and a pendulum.

A pair of trapeze performers at the circus is swinging from ropes attached to a large elevated platform. Suppose that the performers can be treated as a simple pendulum with a length of 16 m. Determine the period for one complete back and forth cycle.
2 sec
12 sec

A pendulum is 0.75 meters long and has a period of 4.17 seconds. The Pendulum is on an unknown planet. What is the acceleration of gravity of the Unknown Planet?
9.8 m/s2
3.4 m/s2

DO NOT GET OUT OF YOUR SPACECRAFT!!! You will float away.
Which would have the longer period Pendulum A or Pendulum B?
Pendulum A: A 200-g mass attached to a 1.0-m length string
Pendulum B: A 400-g mass attached to a 0.5-m length string
A because A is longer thus increasing the period.
B because B is longer thus increasing the period.
A because A has more mass
B because B has more mass
Many amusement parks feature a ride in which a giant ship swings back and forth. If the period of the ship is 6.5 seconds, then what is the frequency of the swinging ship? Make sure to round correctly.
1.53 x 10 -2 Hz
0.15 Hz
0.15384 Hz
1.53 x 102 Hz
What variable affected the Pendulum Period in the lab?
Mass
Length
Time
Gravity
Sam, the butcher, puts 3 kg of chopped beef on the 1 kg pan and places on top of his scale. The scale has a spring constant of 400 N/m. What is the period of vibration of the scale?
0.63 seconds
0.63 Hz
0.54 seconds
0.54 Hz
Sam, the butcher, puts 3 kg of chopped beef on the 1 kg pan and places on top of his scale. The scale has a spring constant of 400 N/m.
What would happen to the force on the scale if Mrs. Wantsmore tells Sam to put more chopped beef on the scale? What type of relationship would this be between mass and force?
Increase mass = increase force, Direct
Increase mass = decrease force, Direct
Increase mass = increase force, Inverse
Nothing because mass has nothing to do with pendulums or springs.
