What is the difference between linear and angular motion ? Explain through example. Linear motion is any motion that moves along a straight line in one direction. ... Angular motion is rotatory motion, it occurs when all points on a body or object move in a circular path about the same fixed central line or axis.

Uniform linear motion is a motion with a constant velocity,whereas uniform circular motion is the motion with a constant speed. ... uniform linear motion is the motion where an object has no acceleration and is travelling with constant velocity.

Answer:- Linear motion (or rectilinear motion) means moving in a straight line. 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.

Angular acceleration is the change in angular velocity divided by time, while tangential acceleration is the change in linear velocity divided by time. People sometimes forget that angular acceleration does not change with radius, but tangential acceleration does.

Angular velocity is the rate of change of the angular displacement over time. Angular velocity multiplied by the radius of movement yields the instantaneous linear velocity of theobject. Linear velocity is measured in meters per second, while angular velocity is measured in radians per second.

In Newtonian rotational physics angular acceleration is inversely proportional to the moment of inertia of a body. You can think of the moment of inertia as the ability to resist a twisting force or torque. The angular momentum of a solid object is just Iω where ω is the angular velocity in radians per second.

So if an object has angular acceleration it is either rotating faster and faster or rotating slower and slower. On the other hand, radial/centripetal acceleration is always present when an object is undergoing circular motion.

Linear velocity v and angular velocity ω of an object are in the same direction as linear and angular momenta, respectively. Since the angular momentum of an object about a reference point is defined to be perpendicular to its linear momentum, the angle between v and ω is always 90 degrees.

The difference between angular velocity and tangential velocity is that “The angular displacement covered by a body in unit time is called angular velocity and tangential velocity is the velocity, which is tangent to the circular path.”

Simple harmonic motion is charcterized by a restoring force that varies linearly with position. ... If the restoring force is the only force acting in the system, then we can write . So we get: If we let then we get which shows us that the acceleration is directly proportional to the displacement.

The radius r is constant for circular motion, and so Δ(rω) = r(Δω). Thus, at=rΔωΔt a t = r Δ ω Δ t . These equations mean that linear acceleration and angular acceleration are directly proportional.

The basic difference between uniform linear motion & uniform circular motion is. Uniform Linear Motion: Velocity is constant & thus it is a uniform motion. Acceleration is zero. Uniform Circular Motion: Velocity is not constant due to continuous change in Direction & thus it is not a uniform motion.

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.

In uniform circular motion, angular velocity (𝒘) is a vector quantity and is equal to the angular displacement (Δ𝚹, a vector quantity) divided by the change in time (Δ𝐭). Speed is equal to the arc length traveled (S) divided by the change in time (Δ𝐭), which is also equal to |𝒘|R.

In linear motion all particles of human body travel the same distance during the same time. Linear motion can be further divided to rectilinear motion and curvilinear motion. In rectilinear motion all particles of the body travel the same distance along parallel straight lines.

No, angular acceleration and radial/centripetal acceleration are two different things. Angular acceleration is the rate at the which the angular velocity changes. Angular velocity is the angular displacement covered over a time interval. ... It is this acceleration that we call the centripetal or radial acceleration.

Angular and linear velocity have the following relationship: v=ω×r v = ω × r . As we use the equation of motion F=ma to describe a linear motion, we can use its counterpart τ=dLdt=r×F τ = d L dt = r × F , to describe angular motion.
