What is the purpose of the Flying Pig lab?
The flying pig lab allows students to investigate the physics and mathematics of uniform circular motion. A motorized, plastic pig is suspended from a thin string and “flies” in a circular path with a constant speed.
Does the pig accelerate in the vertical direction What does this tell you about the magnitude of the vertical component of T and MG?
What does this tell you about the magnitude of the vertical component of T and mg? No. The magnitude of the vertical stays the same. In order for the string to stay stable (not break), the vertical component of T must equal the weight of the pig.
Where is the cos theta in flying pig?
What is the probability of a flying pig?
A pig flying is impossible. It has a probability of 0. It will happen 0 times. The probability of tossing a Head from a coin toss is 1⁄2.
What’s the direction of the net force that keeps the Flying Pig in uniform circular motion?
What do you conclude about the direction of the net force that keeps the flying pig in uniform circular motion? The direction of the net force is towards the center.
Is the magnitude of the tension in the string greater than less than or equal to the centripetal force exerted on the sphere?
In the case that the string is oriented perpendicular to the object’s velocity, the magnitude of the centripetal force is equal to the tension.
How do you find tension in a string in circular motion?
- Formula for tension = centrifugal force = mv2/r.
- So the formula of tension will be = centripetal force – force of gravity = mv2/r – mg = m(v2/r-g)
- The formula of tension will be = centripetal force + force of gravity = mv2/r + mg = m(v2/r+g)
How do you find tension in uniform circular motion?
What is centrifugal force vs centripetal force?
Centripetal force is the force REQUIRED for circular motion. Centrifugal force is the force that makes something flee from the center.
What’s the difference between centripetal and centrifugal?
The main difference between centripetal and centrifugal forces is that the centripetal force is the force pointing towards the center of a circle that keeps an object moving in a circular path, while the centrifugal force is the sensation that an object feels when it moves in that circular path, with that sensation …
What keeps the object moving in circular path?
A centripetal force is a net force that acts on an object to keep it moving along a circular path.
What is the formula for tension force?
Solution: We know that the force of tension is calculated using the formula T = mg + ma.
Is centripetal force always constant?
In this motion, the centripetal force, the force that points towards the center of a circle, is always constant.
Does centripetal force increase with radius?
Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the F c , F c , the smaller the radius of curvature r and the sharper the curve.
Does angle affect tension?
Thus, a decrease in the angle will increase the horizontal component of tension and an increase in the angle will decrease the horizontal component of tension.
How do you solve a tension problem?
- Step 1: Identify the direction of the tension force.
- Step 2: Identify any other forces on the same axis as the tension force.
- Step 3: Identify the acceleration along the tension force axis.
- Step 4: Using Newton’s second law.
- Step 5: Check units to be sure they are in NewtonsN
How do you find tension with mass and velocity?
How is centrifugal force calculated?
- Find the mass of the object – for example, 10 kg .
- Determine the radius of rotation. Let’s assume it’s 2 m .
- Determine the velocity of the object. It can be equal to 5 m/s .
- Use the centrifugal force equation: F = m v² / r .
- Or you can just input the data into our calculator instead 🙂
How do you find centripetal force without velocity?
So, to find the centripetal force, you need to know the mass of the object, the radius of the circle it’s traveling in and its tangential speed. Use the equation above to find the force based on these factors. Square the speed, multiply it by the mass and then divide the result by the radius of the circle.
Is tension constant in circular motion?
2 undergoing uniform circular motion. Thus, we find that the tension in the string increases with the square of the speed, and decreases with the radius of the circle.
Why is centrifugal force fake?
We call it friction. In a similar way, the centrifugal force has very real effects on objects in a rotating reference frame and is therefore real. But the centrifugal force is not fundamental. Rather it is caused by the rotation of the reference frame.
Is gravity a centripetal force?
The force of gravity in keeping an object in circular motion is an example of centripetal force. Since it acts always perpendicular to the motion, gravity does not do work on the orbiting object if it is in a circular orbit.
Why centripetal force is called real force?
This change in direction of motion is possible when an external force acts on the body. this external force is the centripetal force.
As centripetal force is an external force acting on a rotating body, it is a real force.
What are 5 centrifugal forces examples?
- Banked Roads.
- Weight at Poles and Equator.
- A Stone Tied to a Thread.
- Centrifugal Pumps.
- Washing Machine.
- Centrifugal Clutches.
