Concept explainers

Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards…

Simple Pendulum

A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.

Oscillation

In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion tak…

Suspended from the ceiling of an elevator is a simple pendulum of length L. What is the period of this pendulum if the elevator (a) accelerates upward with an acceleration a, or (b) accelerates downward with an acceleration whose magnitude is greater than zero but less than g? Give your answer in terms of L, g, and a.

A space explorer lands on an unknown planet. She decides to measure the gravitational acceleration by tying a rock to the end of a 1.5 m string and using it as a pendulum. She pulls the rock 0.1 m to the right (as shown) and lets go. The pendulum swings with a period of 1.0 s. Assume positive-x is to the right, and x = 0 when the string is vertical. The diagram shows the pendulum at time t = 0. b) What is the gravitational acceleration of the planet, g? write all your final numerical answers using two decimal places. (For example, please write 3.14 instead of, or 1.41 instead of √2, etc) a) What is the angular frequency, w? 1.5m 0.1m c) Write an expression for the horizontal position of the rock as a function of time, x(t). All terms should be evaluated numerically (except t). d) Calculate the maximum horizontal acceleration of the rock. e) Draw a diagram of the pendulum when the rock has the maximum positive acceleration. f) Having measured g, the explorer now wants to use the…

A (12.6 + A) g mass is hung on a string with a length of (68.4 + B) cm. The mass is then pulled back until the string makes a (5.00 + C/10) degree angle from the vertical and released. Find the period of the pendulum. Give your answer in seconds (s) and with 3 significant figures. A=20 B=78 C=8
