What do you mean by angular velocity?

angular velocity, time rate at which an object rotates, or revolves, about an axis, or at which the angular displacement between two bodies changes. In the figure, this displacement is represented by the angle θ between a line on one body and a line on the other.

What are linear kinetics?

Studying the causes of linear motion is the branch of mechanics known as linear kinetics. Identifying the causes of motion may be the most useful kind of mechanical information for determining what potential changes could be used to improve human movement. Correspondingly, how is moment of inertia calculated? Moments of inertia can be found by summing or integrating over every 'piece of mass' that makes up an object, multiplied by the square of the distance of each 'piece of mass' to the axis. In integral form the moment of inertia is I=∫r2dm I = ∫ r 2 d m .

What are kinematical equations of circular motion any two )?

Figure 1: Anti-clockwise motion with speed v around a circle of radius r . The angle θ increases in the anticlockwise direction. A small arc d, l, equals, v, d, t,dl=vdt subtends an angle dθ in a time dt . Can an object rotate without torque? Yes, to rotate , with a constant angular momentum we don't need torque. Torque is need to change the angular momentum.

What is relation between torque and angular momentum?

Relation between torque and angular momentum is given by. r net=dtdL. where, r → torque acting on a body. L → angular momentum of body. Accordingly, what is the relationship between torque and angular velocity? The instantaneous power of an angularly accelerating body is the torque times the angular velocity: P=τω P = τ ω . There is a close relationship between the result for rotational energy and the energy held by linear (or translational) motion.
