Why can a batter hit a pitched baseball further than a ball tossed in the air by the batter?
WHY can a batter hit a pitched baseball further than a ball tossed in the air by the batter? The bat changes the direction of the momentum (with little loss of velocity) and the batter swings at the ball adding more impulse to the ball. These motions combined allow for a home run.
What is the net work done on the crate?
What is the net work done on the crate? The net work done on the crate is zero joules.
Does gravity do negative work on a pendulum?
(a) As the pendulum bob swings from point II to point III, the force of gravity points downward and a component of the displacement is upward. Therefore, the work done on the bob by gravity is negative.
How does gravity affect pendulum?
Force of gravity-This accelerates the pendulum down. The momentum built up by the acceleration of gravity causes the mass to swing in the opposite direction to a height equal to the original position.)
Which of the following do not affect the time period of simple pendulum?
Mass of the bob, and b. Size of the bob does not affect the time period of a pendulum. Also time period of the pendulum is independent of the amplitude provided this is not too great.
What is a simple pendulum define the time period of a simple pendulum?
The time period of a simple pendulum: It is defined as the time taken by the pendulum to finish one full oscillation and is denoted by âTâ. Length of a simple pendulum: It is defined as the distance between the point of suspension to the centre of the bob and is denoted by âlâ.
How can you reduce the time period of a pendulum?
The simplest way to reduce the period of the pendulum is to reduce the length of the string. The pendulum moves front and back in a periodic motion. It is moving on the circumference of a circle only through a fixed motion.
How can we increase the time period of simple pendulum?
increasing the amplitude of oscillations of the bob.
