## How do you find the acceleration of a pendulum?

Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted.

Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find “g.” This is your measured value for “g.”.

## Why acceleration is maximum at extreme position?

When the displacement is maximum, the acceleration is maximum, because the spring applies maximum force; the force applied by the spring is in the opposite direction as the displacement. The acceleration is given by: Note that the equation for acceleration is similar to the equation for displacement.

## Is acceleration constant in a pendulum?

In particular, the acceleration is not constant. The tangential position (measured from the low point of the swing) changes, up to a maximum, the amplitude of the motion.

## What are the position of maximum velocity and acceleration of the bob of the pendulum?

So as the bob moves leftward from position D to E to F to G, the force and acceleration is directed rightward and the velocity decreases as it moves along the arc from D to G. At G – the maximum displacement to the left – the pendulum bob has a velocity of 0 m/s.

## What does a pendulum period depend on?

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. … With the assumption of small angles, the frequency and period of the pendulum are independent of the initial angular displacement amplitude. A pendulum will have the same period regardless of its initial angle.

## What makes a pendulum move?

A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy). … So as the bob swings (oscillates) back and forth, it repeatedly switches its energy back and forth between potential and kinetic.

## Why acceleration is zero when velocity is maximum?

Acceleration is the rate of change of velocity. If you are accelerating,that means every second your velocity is changing. … So once you have reached your maximum velocity, that means your velocity can’t get any higher. So, your acceleration must be zero.

## What happens when acceleration is maximum?

” In Simple Harmonic Motion, the maximum of acceleration magnitude occurs at x = +/-A (the extreme ends where force is maximum), and acceleration at the middle ( at x = 0 ) is zero. ”

## Where is acceleration the greatest?

In simple harmonic motion (for example a spring moving horizontally), acceleration is greatest when the mass reaches either end of the spring. Using the formula F=ma=kx and then a=kxm, it makes sense that acceleration is greatest when x is max.

## What is the acceleration of a pendulum?

A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. 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.

## At what position does the pendulum have maximum and minimum acceleration?

At the highest point of its motion, kinetic energy is minimum (i.e. zero) and potential energy is maximum. The acceleration is a maximum at the end points of the swing, and a minimum (zero) in the middle, at the lowest point. The forces acting are gravity, tension and friction.

## At what point does a pendulum move the fastest?

Potential energy is converted to kinetic energy, which is the energy exerted by a moving object. An active pendulum has the most kinetic energy at the lowest point of its swing when the weight is moving fastest.

## Why do shorter pendulums swing faster?

The only factor that significantly affects the swing of a pendulum on Earth is the length of its string. … A pendulum with a longer string has a lower frequency, meaning it swings back and forth less times in a given amount of time than a pendulum with a shorter string length.

## What does it mean when a pendulum swings back and forth?

When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.

## What is the restoring force of a pendulum?

As for the simple pendulum, the restoring force of the physical pendulum is the force of gravity. With the simple pendulum, the force of gravity acts on the center of the pendulum bob. In the case of the physical pendulum, the force of gravity acts on the center of mass (CM) of an object.

## What keeps a pendulum swinging?

The science behind the pendulum is explained through the forces of gravity and inertia. 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.

## What is the maximum acceleration of a car?

A: You’re right that the maximum acceleration for some cars can be in the neighborhood of g, 9.8 m/s2. That means that the coefficient of friction, μ, has to be around 1 or so.

## When velocity is zero What is acceleration?

Since acceleration is the change in velocity over time, there has to be a change in velocity for something to accelerate. In other words, if something is accelerating, it has to have a variable velocity. If the velocity is constant however, the acceleration is zero (because the velocity isn’t changing over time).
