Q. How did Benjamin Banneker invention change the world?
His early accomplishments included constructing an irrigation system for the family farm and a wooden clock that was reputed to keep accurate time and ran for more than 50 years until his death. In addition, Banneker taught himself astronomy and accurately forecasted lunar and solar eclipses.

Q. How did Benjamin Banneker impact science?
When Benjamin Banneker was born, his family consisted of freed slaves, who did not fulfill the criteria early Americans expected of scientists. Banneker ultimately acquired many scientific titles: inventor, mathematician, surveyor, and astronomer. His work inspired both black and white scientists.
Q. In what city was the clock that changed the world created?
Lincolnshire
Q. How did the pendulum clock affect society?
Galileo and his son had the idea for a pendulum clock in 1637, but neither lived to finish it. The introduction of the pendulum increased the accuracy of clocks enormously from about 15 minutes per day to 15 seconds per day leading to their rapid spread replacing older designs.
Q. How does temperature affect a pendulum?
A pendulum clock keeps proper time at temperature θ₀. If temperature is increased to θ (> θ₀) then due to linear expansion, length of pendulum and hence its time period will increase.
Q. Why is the pendulum important?
Pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.
Q. Who came up with the idea of the pendulum clock?
Q. Who is father of clock?
Thomas Tompion
Q. What keeps a pendulum moving?
The Earth’s gravity attracts the pendulum. This means that since the pendulum is now in motion, it keeps moving, unless there is a force that acts to make it stop. Gravity works on the pendulum while it is moving. The moving force becomes less as the force of gravity acts on the pendulum.
Q. Why do longer pendulums swing slower?
The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. Since the force of gravity is less on the Moon, the pendulum would swing slower at the same length and angle and its frequency would be less.)
Q. Do pendulums go faster with more weight?
That’s why these pendulums behave the way they do. When you add a weight to the bottom of the pendulum on the right, you make it heavier. Shorter pendulums swing faster than longer ones do, so the pendulum on the left swings faster than the pendulum on the right.
Q. What happens if you double the weight of a pendulum?
The mass of a pendulum’s bob does not affect the period. As mass increases, so does the force on the pendulum, but acceleration remains the same. (It is due to the effect of gravity.) Because acceleration remains the same, so does the time over which the acceleration occurs.
Q. How does the angle of release affect a pendulum?
The Equation of Motion When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion.
Q. What affects a pendulum period?
The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity. The period is completely independent of other factors, such as mass. If the length of a pendulum is precisely known, it can actually be used to measure the acceleration due to gravity.
Q. How does air resistance affect a pendulum?
When the pendulum oscillates it carries the air along with it. The air resistance reduces the acceleration and increases the time period of oscillation. The air resistance reduces the velocity of the pendulum and the pendulum gradually comes to rest.
Q. What 3 variables were changed in the pendulum experiment?
3 The three pendulum variables In this experiment, the period of the pendulum is the dependent variable. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string.
