What is Rotional Motion?
Rotational motion is rotation of a body about its center of mass.
How many degrees per second per second equal 1 G?
G is a measure of linear acceleration. For rotational motion it is necessary to multiply the degrees by the distance from the centre of rotation (radius of rotation).
If the torque of the rotational motion be zero then the constant quantity will be?
angular momentum
How are circles and their radius used in science?
Well, motion and range of motion in physics.
Why cams have irregular shape?
They need to convert rotational motion to motion of some other form - usually linear motion. That can only be accomplished through the use of specific irregular shapes.
What does rotational inertia depend on?
Rotational inertia depends on the mass of the object and how that mass is distributed relative to the axis of rotation. It is a measure of how difficult it is to change the rotational motion of an object.
What is the relationship between velocity (v), angular velocity (w), and radius (r) in the context of rotational motion?
In rotational motion, velocity (v) is related to angular velocity (w) and radius (r) through the equation v w r. This means that the linear velocity of a point on a rotating object is equal to the product of the angular velocity and the distance from the center of rotation (radius).
How is rotational speed affected by the radius?
Rotational speed is inversely proportional to the radius. A smaller radius will result in higher rotational speed, while a larger radius will result in lower rotational speed. This relationship is described by the equation v = rω, where v is linear speed, r is radius, and ω is angular velocity.
What is the relationship between the angular acceleration formula and linear acceleration in rotational motion?
The angular acceleration formula is related to linear acceleration in rotational motion through the equation a r, where a is linear acceleration, r is the radius of rotation, and is angular acceleration. This equation shows that linear acceleration is directly proportional to the radius of rotation and angular acceleration.
What is the difference between oscillating and rotational motion?
Rotational motion is motion which emulates that of the minute hand of a clock. Oscillating motion is motion which emulates that of the pendulum.
What is the moment of inertia of a hoop?
The moment of inertia of a hoop is equal to its mass multiplied by the square of its radius. It represents the resistance of the hoop to changes in its rotational motion.
What is the is the measure of an object's resistance to a change in its rotational motion about an axis called?
The measure of an object's resistance to a change in its rotational motion about an axis is called inertia. It is similar to an object's resistance to a change in its linear motion, but it specifically refers to rotational motion. The greater an object's inertia, the more difficult it is to change its rotational motion.
What is the Difference between periodic motion and rotational motion?
Periodic motion repeats itself at regular intervals, such as the swinging of a pendulum. Rotational motion involves objects spinning or turning around an axis, like a wheel spinning on its axis. While periodic motion follows a pattern of repetition, rotational motion involves circular movement around a fixed point.
Can an object have rotational motion and rectilinear motion?
Yes.
Which force is associated with rotational motion?
Two forces associated with rotational motion are centripetal force and centrifugal force.
Are all rotational motion periodic?
Yes, rotational motion can be periodic if it repeats its motion after a certain time interval. This periodic nature can be observed in objects such as a spinning top or a pendulum.
What is the rotational analog of mass in linear motion?
The rotational analog of mass in linear motion is moment of inertia. It represents an object's resistance to changes in its rotational motion, similar to how mass represents an object's resistance to changes in its linear motion.
