Practice PE Civil Rotational Motion in the app →An engineer records the angular position of a shaft. The unit used is the:Because it is a ratio of two lengths, the radian measure is:The time rate of change of angular position is the angular:Angular velocity is measured in radians per:The tangential speed of a point on a rotating body equals angular velocity times the:A point twice as far from the axis therefore has a tangential speed that is:The direction of the angular velocity vector is found using the rule known as:Tangential velocity is obtained from angular velocity and the position vector by taking their:A skater pulling their arms inward while spinning shows a change in angular:Angular acceleration is measured in radians per second per:The quantitative measure of rotational inertia is the moment of:The rotational kinetic energy of a rigid body is proportional to the square of the angular:Storing energy in a heavy spinning wheel exploits rotational kinetic energy in a device called a:Computing the moment of inertia of a compound object is eased by the theorem named:The SI unit of torque is the newton multiplied by the:The perpendicular distance from the axis to the line of the force is called the:Several torques acting about one axis are combined by finding their:Acceleration caused by the change in direction of tangential velocity is called:Unlike linear position measured in metres, angular position is measured in units that are:The more massive an object is, the more of this it has in linear motion:Six washers on a light rod illustrate the moment of inertia of a system of:The branch describing the motion of a rotating rigid body about a fixed axis is rotational:
