When motion is the normal component of acceleration is zero?

Q.

When can the acceleration of an object be zero?

Yes. Typically, if the velocity is a constant, then the acceleration is zero. Acceleration is the rate of change of the velocity. So as long as the velocity does not change (no matter what value it has), the acceleration is zero.

How do you know when the acceleration is zero?

If change in velocity is 0. Accleration will be zero. In other words acceleration is zero if velocity is constant.

What is the normal component of the acceleration?

centripetal component
The normal component of acceleration is also called the centripetal component of acceleration or sometimes the radial component of acceleration. To understand centripetal acceleration, suppose you are traveling in a car on a circular track at a constant speed.

Is normal acceleration always positive?

Note that the tangential acceleration ¨ s can be either positive or negative, while the normal or centripetal acceleration is always positive, because the product ˙ s ˙ θ = v 2 / R is always positive ( s and θ both increase, if the motion is in the direction of the tangential unit vector, or both decrease if the motion …

When a point is moving in a curved path the normal acceleration is equal to?

a particle is moving on a curve path, the component of acceleration in the direction of velocity is tangential acceleration, while the component of acceleraton Rependicular to velocity is normal or centripetal acceleration.

Can a particle have acceleration with zero velocity?

Answer: Yes, an object can have zero velocity and still be accelerating simultaneously.

What is meant by normal acceleration?

the component of acceleration for a point in curvilinear motion that is directed along the principal normal to the trajectory toward the center of curvature; normal acceleration is also called centripetal acceleration.

Can the normal component of acceleration be negative?

What is the meaning of zero acceleration?

If the change in velocity is zero i.e. either the object is at rest or moving with uniform velocity then the object is said to have zero acceleration.Example: a parked car a train moving with a constant speed of 90 km/hr.

When a particle moves along a straight path then the particle has?

Explanation: When a particle moves along a straight path, then the radius of curvature is infinitely great. This means that v2/r is zero. In other words, there will be no normal or radial or centripetal acceleration. Therefore, the particle has only tangential acceleration.
