Q:

What is angular motion?

A:

Quick Answer

Angular motion is the motion of a body about a fixed point. The motion of pendulums and planets are examples of angular motion. Angular motion can also be used to describe the angle made during the motion of a body about a fixed axis.

Full Answer

Motion is the change in position of an object from its initial position to its final position with respect to time. Angular displacement or rotational displacement is the angle passed over at the point by a line drawn from the given axis of rotation, and it is expressed in radians. Angular motion with constant acceleration occurs in a machine with spinning parts.

  • Q:

    What is vibratory motion?

    A:

    Vibratory motion occurs at a fixed point as an object moves back and forth. It can also be defined as an object forced to move to and fro periodically, occurring when a particle is vibrated. Oscillatory motion is related to vibratory motion.

  • Q:

    How do you find angular velocity?

    A:

    Find the angular displacement using the formula ? = d?/dt, ?/t or v/r. "?" represents the angular velocity, "d?" represents change in angular displacement, "dt" stands for change in time,"?" represents displacement and "t" represents time taken. "V" is the linear velocity, and "r" is the radius of circular path.

  • Q:

    What is the angular acceleration formula?

    A:

    While there are several formulas for angular acceleration, the basic equation is the change in angular velocity divided by the change in time. This relationship is shown in the following equation: (Av2 - Av1)/(T2 - T1).

    What is the law of inertia?

    A:

    The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.
