What is translational motion? Explain
Answers
Answer:
Translational motion is the motion by which a body shifts from one point in space to another. One example of translational motion is the the motion of a bullet fired from a gun. An object has a rectilinear motion when it moves along a straight line.
Answer:
Explanation:
When a body is shifted or moved from one point to another point, then the body said to be experienced translational motion. It is the motion in which all points of a moving body move uniformly in the same line or direction. If an object is executing translational motion then there is no change in its orientation relative to a fixed point
So,
If the object moves such that all the particles in the object move parallel to each other then the motion is called pure translational motion.
In this type of motion, all points of the body have velocities and accelerations that are the same in magnitude and direction at every instant of time. All points describe identical trajectories. By this, we mean that trajectories would coincident when they are placed one above the other. Basically, the orientation of the body remains fixed relative to a fixed axis.
Also from the definition of translatory motion for an object to execute Translational motion, there is no change in its orientation relative to a fixed point and all points of a moving body move uniformly in the same line or direction. This is not the case when rotational motion is involved. In the case of rotational motion,
the object turns about an axis and change of orientation takes place. One example of rotational motion is the rotation of earth along its own axis.
Also in case of rotational motion object travels an increase of angle with the change or increase in time. For a rotating body, if the increment in angle is small, we can consider the curve to be an arc on a circle at any point in time. The arc length depends on increment in angle and the radius of rotation, which is the distance between the object’s center of mass and the axis of rotation. So, points at different distances from the axis of rotation have different arc lengths for the same angle of rotation.
In rotational motion, we describe motion in terms of angular velocity, angular acceleration, etc.
