Velocity as a Vector Quantity Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity.

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction.

3 Answers. The lowest velocity occurs right as acceleration changes direction. That is, we need to find the time τ when v′(τ)=0 so that the minimum speed is given by v(τ).

and that the minimum speed is zero at the two x-intercepts. Minimum and maximum speed: For a continuous velocity function, the minimum speed is zero whenever the maximum and minimum velocities are of opposite signs or when one of them is zero.

When the distance from the equilibrium point(where the body has to stop)decreases the acceleration also decreases about velocity we all know that velocity is inversely proportional to distance from equilibrium meaning as displacement increases the velocity decreases so when the body pass through the mean point the …

At the top, tension is given by T = mvT2/R – mg, where vT = speed of the particle at the top. Note: In case the particle is attached with a light rod of length l, at the highest point its minimum velocity may be zero. Then, the critical velocity is 2√gl.

So, when velocity is maximum, acceleration is minimum (zero).

First that the maximum acceleration is dependent on the coefficient of friction. If μs = 1, then the maximum acceleration would be 9.8 m/s2. Of course, for real humans, they can’t have an acceleration this high for very long.

In SHM, velocity is maximum at equilibrium position. vmax = aω velocity is minimum at extreme position.

The velocity of the mass on a spring, oscillating in SHM, can be found by taking the derivative of the position equation: Because the sine function oscillates between –1 and +1, the maximum velocity is the amplitude times the angular frequency, vmax=Aω v max = A ω .

The maximum displacement of the bob from its mean position, i.e. OA or OB is called its amplitude. For this reason its velocity is maximum at the mean position. The bob is its highest point at either of its extreme positions. Here its potential energy is maximum while the kinetic energy is zero.

STATEMENT-1 : In simple harmonic motion, at extreme position the velocity and acceleration of object is zero.
