Circular Motion Basics

This page covers the fundamentals of moto circolare uniforme, including angular measurements and velocities.

Definition: Circular motion involves movement along a circular path, characterized by angular quantities.

Vocabulary:

• Angular position (θ)
• Angular velocity (ω)
• Tangential velocity (v)
• Frequency (f)

Highlight: One complete rotation equals 360° or 2π radians, with counterclockwise motion considered positive and clockwise negative.

Example: For uniform circular motion, the angular position is given by θ = θ₀ + ωt, where ω is constant.

Centripetal Acceleration and Range

The final page focuses on accelerazione centripeta and projectile range calculations.

Definition: Centripetal acceleration is directed toward the center of the circular path and is given by ac = v²/r = rω².

Highlight: The range (gittata) of a projectile depends on initial velocity and launch angle, with maximum range occurring at 45°.

Example: For a 45° launch angle, the range is given by G = Vo²/g, where Vo is the initial velocity and g is gravitational acceleration.
