How does air resistance affect pendulum?
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.
What is the equation for force of air resistance?
The net external force is equal to the difference between the weight and the drag forces (F = W – D). The acceleration of the object then becomes a = (W – D) / m . The drag force depends on the square of the velocity.
Does air resistance slow a pendulum?
I know that “perfect” pendulums would be able to swing forever, unperturbed by air resistance. However, since there is air resistance around us, pendulums (swinging bobs) slow down and move closer and closer to a halt.
What is the formula of time period of simple pendulum?
The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
What are the factors that affect a pendulum?
The forces of gravity, the mass of the pendulum, length of the arm, friction and air resistance all affect the swing rate.
What affects the air resistance?
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity.
What variables affect the period of a pendulum?
The mass and angle are the only factors that affect the period of a pendulum. b. The mass, the angle and the length are the three variables affecting the period.
How does angle affect pendulum period?
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. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)
