Conceptual Physics Unit 3 Circular Rotational and Orbital motions

The 3 Combination motions

Rolling, Spinning, Orbiting

Rolling

is the motion where object spins over itself

Spinning

is the motion of a object spinning along its own internal axis

orbiting

is the motion in which a object is spinning around another object

periodic motion

motion that is repetitive in nature

Examples of periodic motion

rotational and circular motions are repetitive in nature

Tangential velocity

the instantaneous linear speed of an object moving along a circular path

Translational Motion

Movement where an object shifts from one point to another without rotating

Linear Motion

A specific type of Translational motion where an object moves forward in a straight line

Parabolic Motion

A type of curved translational motion where an object is thrown or projected into the air and moves along a curved, arch-like path (a parabola) under the influence of gravity.

Circular Motion

Movement of an object along a circular path or a fixed-radius orbit around a central point.

Tangential Velocity Term

Period(T)

Time is takes for an object to complete a full cycle

Frequency(f)

number of cycles or revolutions per second

Frequency unit

Hertz (Hz)

Unit of △θ

Radians

Unit of ω

Radians/Seconds

Unit of α

Radians/seconds²

Rotational speed are all the same (True or False)

TRUE, ωA=ωB=ωC

What does AOR stand for

Axis of rotation

Centripetal (Center seeking)

a force, or motion, that proceeds or is directed toward a center or axis

Centripetal force (Fc)

The net force acting on a object in circular motion

What are the 4 examples of centripetal force (Fc)

Tension, Gravity, Friction, Normal force turning on a incline

Centripetal acceleration Ac

Acceleration an object experiences in circular motion
