While a body in motion cannot have zero average velocity, there are many examples where the average velocity - after selected intervals - is zero.

For example:

a pendulum, or any object under simple harmonic motion, after a complete number of cycles;

a rotating object (point on a wheel or hand of a clock) after a whole number of circuits.

No, a body in motion can have zero average velocity if it returns to its initial position over the same amount of time it took to move away from it. This would result in a net change in position of zero, thus giving it an average velocity of zero.

Can the average velocity of a body be the same as the instantaneous velocity?

Yes, but in uniform motion.


Can the average velocity of a body be the same as the instateneous velocity?

Yes, But in uniform motion only.


What will be the body said ----- velocities when average and instantaneous velocities are equal?

When the average velocity of a body is equal to its instantaneous velocity, it means that the body is moving at a constant speed in a straight line. This indicates that the body's motion is uniform, with no acceleration or deceleration occurring.


Can a body move with a constant velocity in an accelerated motion?

No, a body cannot move with a constant velocity in an accelerated motion. Accelerated motion implies a change in velocity over time, so the velocity of the body would not remain constant.


How are a body at rest and body moving similar in velocity?

Both a body at rest and a body moving have a velocity of zero at a single point in time. The difference lies in their average velocities over a period of time - a body at rest maintains a constant velocity of zero, while a body in motion will have a non-zero average velocity over that period.


What is the measure of the motion of a body equal to the product of its mass and velocity?

The measure of the motion of a body equal to the product of its mass and velocity is momentum. Momentum is a vector quantity that describes the motion of an object and is calculated as the product of the mass and velocity of the object.


What is tha rate of directed motion of a body at an instant?

The rate of directed motion of a body at an instant is referred to as its velocity. Velocity comprises both the speed of the body and its direction of motion. It is a vector quantity, indicating both the magnitude and direction of motion at a specific point in time.


What is acceleration of body having uniform motion?

A body experiencing uniform motion does not have any acceleration. Acceleration is the rate of change of velocity, and since the velocity of a body in uniform motion remains constant, there is no change in velocity and therefore no acceleration.


Can a body be in motion but 0 acceleration?

Yes, a body can be in motion but have zero acceleration if it is moving at a constant speed in a straight line. Acceleration measures the rate of change of velocity, so if velocity is constant, acceleration is zero even though the body is in motion.


What happens to the momentum of a body acted on by an external force?

If the force opposes the motion, it will reduce the velocity and the momentum of the body will decrease. If the force is in the direction of the motion, the velocity will increase and the momentum will increase.


Consider the instantaneous velocity of a body this velocity is always in the direction of what the net force at that instant the least resistance at that instant or the motion at that instant?

The instantaneous velocity of a body is always in the direction of the resultant force acting on it at that instant. It is influenced by the net force and not necessarily by the least resistance or the current motion of the body.


Can a body in equilibrium if it is in motion?

It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
