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.

What newton first law of motion?
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
What does Newton's 1st law of motion state?
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion in a straight line at constant velocity unless acted upon by an unbalanced force.
Can a body have nonzero average speed but have zero average velocity give example?
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0
What are the two parts of newtons first law of inertia?
Newton's first law states that a body at rest will remain at rest and a body in motion will remain in motion in a straight line at constant velocity unless acted upon by an unbalanced force. So the two parts involve a body at rest and a body in motion.
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.
Find average acceleration and instanious acceleration?
average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.
Can a body have zero velocity and still be accelerating?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
Can a body move with a constant velocity in an accelerated motion?
No. The definition of acceleration is change in velocity.
What happens to the velocity of a moving body if you change the direction in which the body is moving?
It depends how you changed the direction of the body. If the body is hit by an external force in the direction of motion, the velocity should increase. If the body is hit by an external force in the opposite direction of motion, velocity will decrease.
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.
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)
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 motion at that instant
What is unifom velocity?
when a body travels unequal displacement in equal interval of time or visa-versa, it is said to have non-uniform velocity
Do balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
What newton first law of motion?
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
