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.

How do you find the velocity of a flying pig?
In what direction horizontal or vertical does the pig accelerate?
In what direction, horizontal or vertical, does the pig accelerate? (Horizontal only.)
How does the flying pig overcome air friction?
How does the pig overcome air friction? Because net force equals air friction, it results in a constant velocity that propels the pig to fly in a circle.
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.
Where is the cos theta in flying pig?
Is centripetal force equal to tension in uniform circular motion?
For example, if a ball is attached to a string and released from a vertical height and then pivots around a point to initiate circular motion, tension is equal to centripetal motion.
What happens when the force is directed to the direction of the object moving?
This implies that the object accelerates in the same direction as that of force, hence the speed of the object will increase after applying a force in the direction of its 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 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 causes centrifugal force?
When you swing an object around on a string or rope, the object will pull outward on the rope. The force you feel is called the centrifugal force and is caused by the inertia of the object, where it seeks to follow a straight-line path.
What happens if centripetal force is absent?
Without a net centripetal force, an object cannot travel in circular motion. In fact, if the forces are balanced, then an object in motion continues in motion in a straight line at constant speed.
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.
Is centripetal acceleration positive or negative?
Thus the magnitude of the acceleration is v2/r and its direction is along the radius and the negative sign indicates that it is opposite to the radius vector i.e. the acceleration is directed towards the centre of the circular path. This acceleration is called the centripetal acceleration.
In which state a body has zero speed?
A body has zero speed when it has zero distance covered in an interval of time and hence the body is at rest. Was this answer helpful?
What are the 5 forces of motion?
- Applied Force.
- Gravitational Force.
- Normal Force.
- Frictional Force.
- Air Resistance Force.
- Tension Force.
- Spring Force.
Is acceleration dependent on velocity?
That’s because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction. Thus, a falling apple accelerates, a car stopping at a traffic light accelerates, and the moon in orbit around the Earth accelerates.
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.
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.
- Drifting.
- Weight at Poles and Equator.
- A Stone Tied to a Thread.
- Merry-Go-Round.
- Centrifugal Pumps.
- Washing Machine.
- Centrifugal Clutches.
Is centrifugal force a real force?
centrifugal force, a fictitious force, peculiar to a particle moving on a circular path, that has the same magnitude and dimensions as the force that keeps the particle on its circular path (the centripetal force) but points in the opposite direction.
What is centrifugal force in simple words?
Definition of centrifugal force : the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of rotation — compare centripetal force.
Why is centripetal force equal to weight?
If the only forces acting on a body are centripetal and weight (C and W) and that body under consideration is not moving such that acceleration a = 0, then f = ma = 0 = C + W; so that C = -W, the centripetal force must be equal and opposite to the weight.
Does Earth have centrifugal force?
Since Earth rotates around a fixed axis, the direction of centrifugal force is always outward away from the axis. Thus it is opposite to the direction of gravity at the equator; at Earth’s poles it is zero.
