What is the acceleration of a particle moving in a straight line?

The acceleration of a particle moving in a straight line varies with its displacement as, a= 2s velocity of the particle is zero at zero displacement.

When the acceleration of a moving particle is zero What is it?

Theoretically, when a particle moves in constant velocity, there is no change in velocity with time. Then its acceleration is called zero acceleration. Mathematically, since velocity is constant then the first time derivative of velocity will be zero which indicates the acceleration of a moving object.

What is the velocity of the particle at t 0?

A particle is moving along x-axis with acceleration a=a0(1-t/T) where a0 and T are constants. The particle at t=0 has zero velocity.

When acceleration is constant What is the velocity of a particle?

Acceleration zero – Velocity of a particle is constant.

What is the acceleration of a particle moving with uniform velocity?

An object moving at uniform or constant velocity has zero acceleration.

When a particle is moving with uniform acceleration then?

Answer: If the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 5 m/s to 2 m/s over one second, its constant acceleration is −3 m/s2.

Is zero acceleration constant acceleration?

NO. Because zero acceleration means no change of acceleration. That is no increase or decrease of acceleration throughout the path. In the other hand constant acceleration means constant increase or decrease of acceleration.

When velocity of a particle is zero then acceleration of particle is zero?

The acceleration at t=0 must be zero.

How do you find the velocity of a particle at time t?

The instantaneous velocity v(t) of a particle is the derivative of the position with respect to time. That is, v(t)=dxdt. This derivative is often written as ˙x(t), or simply as ˙x.

When 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.

How does the acceleration of a particle vary with its position?

The acceleration of a particle which moves along the positive x – axis varies with its position as shown. If the velocity of the particle is 0.8 m/s at x = 0 , the velocity of the particle at x = 1.4 is (in m/s). The acceleration of a particle which moves along the positive x-axis varies with its position as shown.

What is the intial velocity of the particle?

The distance covered by a particle moving along a straight line path with uniform acceleration is x=6+7t+10t^2 meter. What is intial velocity of the particle? Fast. Simple. Free. Get rid of typos, grammatical mistakes, and misused words with a single click. Try now. the answer is pretty simple. It is 7m/s.

Is it necessary for a particle with uniform speed to move?

The magnitude of velocity vector and speed are same at any instant of time (i.e instantaneous speed = magnitude of instantaneous velocity vector). No, it is not necessary that the particle which has uniform speed is moving on a straight line. Speed is the rate of change of distance with respect to time. The distance is the path length.

What is the difference between the magnitude of velocity vector and speed?

The magnitude of velocity vector and speed are same at any instant of time (i.e instantaneous speed = magnitude of instantaneous velocity vector). Only when the average velocity and average speed is calculated then the difference comes. Example: Let’s say a particle is moving in XY plane on the curve y = x 2.
