When a ball is tossed straight up it momentarily comes to a stop at the top of its path Is it in equilibrium during this brief moment?
No, the ball does not stop. Relative to the ground that is.
I am replacing the last answer which read "yes it will stop".
The author of this answer was thinking digitally. Anotherwords, real life events can be measured as a bunch of steps showing changing velocity.
In reality, natural movement in the world around us is continually variable (analogue).
The ball travelled upward, then changed direction and fell to the ground. If we are to say that it stopped we would have to elaborate by saying it was at rest for no longer than zero seconds.
Anotherwords, the change in direction from up to down was flawless. Up, then down, there was never a period of inbetween.
Even if a computer thinks there was. A digital computer cannot record even one second of true analogue data, so how can it know!
Hope this helps.
Its a hard concept to get your head around because it deals with the concept of infinity.
What else can I help you with?
Is momentarily an adverb?
Yes.momentarily |ˌmōmənˈte(ə)rəlē|adverb1 for a very short time : as he passed Jenny's door, he paused momentarily.2 at any moment; very soon : my husband will be here to pick me up momentarily.
Does the location of a moment matter in static equilibrium?
No, the location of a moment does not matter in static equilibrium as long as the total sum of moments acting on an object is zero. In static equilibrium, an object remains in a fixed position without rotating under the influence of external forces.
When is a dipole in unstable equilibrium in an electric field?
A dipole is in unstable equilibrium in an electric field when the external electric field opposes the natural alignment of the dipole moment. This causes the dipole to experience a torque that rotates it away from its equilibrium position. If the force pushing the dipole away from equilibrium is stronger than any restoring forces, the equilibrium is considered unstable.
What happens when a clockwise moment and an anticlockwise moment are equal?
When a clockwise moment and an anticlockwise moment are equal, they balance each other out, resulting in no overall rotation. This is known as rotational equilibrium, where the object remains stationary and does not rotate.
What is moment of harmonic rest is called?
The moment of harmonic rest in a vibrating system is called equilibrium position. It is the position where the restoring force is zero and the system is in a state of balance.
What does momentarily mean?
In a moment.

What are the conditions for a body stopped momentarily?
For a body to be momentarily stopped, its velocity must be zero at that instant. This means that there is no net force acting on the body, causing it to remain at rest for that brief moment.
What can you conclude about the pendulum at the instant shown by the graph below (just past 2 s)?
At the instant just past 2 seconds, the pendulum is at its maximum displacement from the equilibrium position, indicating it is momentarily at rest before changing direction. The velocity of the pendulum is zero at this point, and the restoring force is at its maximum, pulling it back towards the equilibrium. The pendulum is experiencing maximum potential energy and minimum kinetic energy at this moment.
A ball thrown straight up has zero velocity at its highest point Is the ball in equilibrium at this point?
Yes, the ball is in equilibrium at its highest point because its acceleration is zero at that point. The forces acting on the ball (gravity and air resistance) are balanced, resulting in a net force of zero.
Which orientation of an electric dipole in an uniform electric field would correspond to unstable equilibrium?
So interesting query! As we keep the dipole with its dipole moment along the direction of the electric field then it will be in stable equilibrium. IF we keep the same dipole inverted ie its dipole moment opposite to the external field then the dipole will be in unstable equilibrium.
Where did bless you come from when a person sneezes?
It was once believed that the violence of a sneeze, momentarily displaced your soul from your body. During that moment, people thought the devil could step in, and take you over. By saying "bless you" someone else could keep the devil from inhabiting you.

When is a dipole in unstable equilibrium in an electric field?
A dipole is in unstable equilibrium in an electric field when the external electric field opposes the natural alignment of the dipole moment. This causes the dipole to experience a torque that rotates it away from its equilibrium position.
