Answer. A pendulum is a freely hanging weight suspended from a pivot.
Answer. It is the movement of the object in a direction where the object in another direction feels an equal movement.
Answer. A simple pendulum demonstrates periodic motion.
Answer. The time period of a pendulum is given by the formula:
Answer. The gap between the centre of the bob and the point of suspension gives the length of a pendulum.
Answer. The mass present at the end of a thin cord of a pendulum is known as the bob.
Answer. They would have a longer period.
Answer. The mass on a pendulum does not affect the swing of the pendulum.
Answer. Changing the weights and the distance pulled to swing has no effect on the time taken to finish a swing from an initial to the final position.
Answer. The law of mass states that the time period of a pendulum is independent of the hanging weight.
Answer. The opposition to free vibrations of bob in a simple pendulum due to the presence of air around it is known as damping.
Answer. A pendulum whose time period is two seconds is called a seconds pendulum.
Answer. A spring pendulum has no effect on its time period due to a change in the value of g.
Answer. The amplitude of a simple pendulum is the distance travelled by the pendulum from the equilibrium position to one side.
Answer. Yes, pendulums are used in clocks.
Answer. The potential energy of a simple pendulum is given by the formula: PE=
Answer. The formula to find the kinetic energy of the pendulum is
Answer. Mechanical energy = Kinetic energy + potential energy
Answer. Yes. If the temperature of a system varies, the time period of the pendulum also varies since the length of the pendulum changes.
