In 1851, a French physicist named Jean-Bernard-Leon Foucault suspended an iron ball with a radius of approximately 0.5 feet from the ceiling of the Pantheon in Paris with a wire that was over 200 feet long. The ball was used as a pendulum, and it could swing more than 12 fee
Title: Uniform Circular Motion
Objective: To investigate the relationship between FnetT² and radius
Proposed Hypothesis: FnetT² is directly proportional to the radius
Manipulated variable: Radius of the circular motion
Responding variable: The time taken for 20 rotations
Uniform Circular Motion – a constant motion along a circle; the unfirom motion of a body along a circle
Frequency (f) – the number of cycles or revolutions completed by the same object in a given time; may be expressed as per second, per minute, per hour, per year, etc.; standard unit is revo

II Uniform Circular Motion
1. Speed – magnitude of an objects rate of motion (no direction, scalar quantity)
2. Velocity – speed and direction of an objects motion (vector, mag & direction)
3. If a car’s speed is constant but direction is changing, velocit
Circular Motion and Gravitation
Circular motion is everywhere, from atoms to galaxies, from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general, we say that an object rotates when the axis of rotation lies within the body, and that it revolves when the a
What keeps the stopper moving in a circle?
Purpose: Relate the variables involved in uniform circular motion
Hypothesis: I predict that the velocity of the stopper will increase as the radius is shortened.
Rubber stopper with a hole
PVC tube or wooden spool

Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius, r, is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the positio

We know that angles can be measured in degrees. They can also be measured in something called Radians*, where
Angle (in radians) =
Transformation Lab Report
Transformation is the transfers of virulence from one cell to another, through the transferring of genetic material. It was originally postulated in 1928 through the works of Federick Griffith, a British microbiologist. Griffith observed that the mutant for
2.6.1 Draw a vector diagram to show that the acceleration of a particle moving with uniform speed in a circle is directed toward the centre of the circle.
Review of basic kinematics: If the acceleration and velocity of an object are parallel (or anti-parallel) then the object's speed will increase

In this experiment, we test factors which affect friction. We pulled a wood block across a
surface to determine whetherthe surface area ofthe block orthe type ofsurface affectsfriction.
We found that the surface area of the block did not change the coefficient of kinetic friction,
