## What are two ways to increase a centripetal force?

However here the acceleration is centripetal acceleration . Thus Centripetal force can be increased , by increasing the mass , increasing the centripetal acceleration or by increasing both the mass and centripetal acceleration.

## What is the purpose of a centripetal force lab?

Centripetal Force and Speed The purpose of this lab is to investigate the relationship between the speed of an object in uniform circular motion (UCM) and the centripetal force on the object.

**What factors affect the centripetal force acting on an object?**

Three factors which affect the centripetal force are:

- mass of the object;
- its speed;
- the radius of the circle.

### What do you think is the reason why the Penny stayed in the coat hanger while you were swinging it back and forth?

According to Newton’s first law of motion, objects in motion tend to remain in motion unless acted upon by an external force. So, Force of the hanger is equal to the mass of the hanger and penny, times the acceleration given by swinging the hanger.

### What causes an increase in centripetal force?

This is a force that pulls an object towards the centre of a circle. When an object’s velocity is perpendicular to the direction a force is applied, such as tension on a rope, it will move in a circle. The centripetal force increases if an object is moved closer to the centre of the circle.

**What happens when you increase centripetal force?**

So the velocity v of the object increases proportionally(square root times) to compensate for the increase in centripetal force. For example if the centripetal force is increased 4 times(keeping the radius r constant), the linear velocity v increases by 2 times.

#### How does centripetal force change with radius?

Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the F c , the smaller the radius of curvature r and the sharper the curve.

#### How does centripetal force affect period?

The period of an object () can be calculated where is the speed. So, if radius and mass are held constant, centripetal force is inversely related to the square of the period.

**How do you increase centripetal acceleration?**

If you are keeping the angular speed constant (which is the same as keeping the frequency of revolution or the period constant) then the centripetal acceleration would increase. An example of this would be moving away from the centre of a rotating carousel.

## What happens to centripetal force when mass is doubled?

An object has a mass M, velocity V, and moves in a circle with radius R. What happens to the centripetal acceleration on the object when the mass is doubled? Possible Answers: The centripetal acceleration is doubled.

## What kept the coin against the coat hanger?

the centripetal force

The force that keeps the coin stuck to the coat hanger is called the centripetal force.

**How does the coin drop experiment work?**

The coin has inertia, meaning it really wants to stay in one place. If you move the card slowly, it isn’t fast enough to overcome that force. If you flick it quickly, the coin stays in one place and then drops into the cup. An object at rest will remain at rest.

### What is the formula for finding the centripetal force?

Centripetal force formula. Centripetal force equation can be derived from Newtonâ€™s second law of motion as: F = mv 2 /r. Where, F represents the centripetal force, m is mass, v is the velocity, and. r refers to the radius. How to find centripetal force? To find centripetal force without using a centripetal force solver, follow the below steps:

### What is a real life example of centripetal force?

The centripetal force acts on objects moving towards circular motion. Centripetal force is a real force that acts on both inertial and non-Inertial frames. The formula of the centripetal force is: F c = mv2 r m v 2 r . Merry Go Rounds, washing machine dryers are real-life examples of Centripetal force.

**How to calculate centripetal force?**

– I. Cutting the World Up and Putting it Back Together with Mathematics. – II. Thinking Numerically – Computational Thinking: The Computer. The Harvard Mark I and ENIAC marked the culmination of the development of a mechanical calculator, and the latter marked the turning – III. Generating the World.

#### How do I find the centripetal force?

Centripetal force is measured in Newtons and is calculated as the mass (in kg), multiplied by tangential velocity (in meters per second) squared, divided by the radius (in meters). This means that if tangential velocity doubles, the force will quadruple.
