How do you find acceleration in rotational motion?
Angular acceleration α is defined as the rate of change of angular velocity. In equation form, angular acceleration is expressed as follows: α=ΔωΔt α = Δ ω Δ t , where Δω is the change in angular velocity and Δt is the change in time.
What is translational motion explain with examples write its main types compare them according to their differences and similarities?
But, if a body changes its position with respect to time, we say that it is in motion. There are different types of motion: translational, rotational, periodic, and non-periodic….Rotational Motion.

What is meant by rotational motion How is it different from translational motion?
Translational Motion: Translational motion is motion that involves the sliding of an object in one or more of the three dimensions: x, y or z. Rotational Motion: Rotational motion is where an object spins around an internal axis in a continuous way.
What is centripetal acceleration derive an expression for it for a body moving in uniform circular motion?
|→a|=ωR2√(sinωt)2+(cosωt)2=ωR2 $sin2θ+cos2θ=1$ Hence centripetal acceleration is ωR2. Note: As we derived the expression for centripetal acceleration of the body undergoing uniform circular motion, we can see that the magnitude of this acceleration is constant with time.
What is rotational motion explain it with example?
Rotational motion can be defined as a motion of an object around a circular path, in a fixed orbit. It can also be defined as the motion of a body, in which all of its particles move in a circular motion with a common angular velocity, about a fixed point—for example, the rotation of Earth about its axis.
How will you distinguish between rotational motion and curvilinear translation of a rigid body?
If the paths of motion are along curved lines which are equidistant, the motion is called curvilinear translation. 2. Rotation about a fixed axis: When a rigid body rotates about a fixed axis, all the particles of the body except those which lie on the axis of rotation move along circular paths. 3.
What causes translational motion?
Translatory motion or translational motion occurs when all points in a body move the same distance in the same amount of time. The translatory motion does not always require that the object move in a straight line. We can use the term translational motion when the object is moving in 2- or 3-dimensional bodies.
