How is it possible to exert force on an object without changing the velocity of an object?

"for every action there is an equal and opposite re-action" which means in this case that the force being applied to the object is not enough to overcome the mass of the object and for it to move as a result.

∙ 13y agoThis is only possible when the forces are balanced -- The net force is 0. For example, an object sitting on a desk at rest is being affected by 2 forces: gravity and normal force, but both are pushing at equal magnitudes in opposite directions, so they are balanced.

∙ 12y agoYes, if other forces act as well. In order for there to be no acceleration, the sum of the forces on the object must equal zero. In order for there to not be acceleration, another force would have to counteract your force.
If you exert a force and no other forces are present, then there will be acceleration.

Can an object have a constant spped and velocity at the same time?
Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.
Traveling without changing speed?
When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
Describe a situation in which the car has zero speed but has a definite acceleration?
An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.
What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
How fast an object is changing its position with time is?
Its velocity
An object traveling at a constant 20 miles per second in a circular path is changing what?
This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.

When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
Can an object have a constant speed and a varying velocity?
Yes. Velocity is a quantity that has both magnitude and direction. Speed is the magnitude of velocity. If speed is constant but the direction is changing, then the velocity is changing. An example is a car turning a corner without slowing down.
Is it possible for a nonzero net force to act on an object without the object's speed changing?
Yes, it is.
Describe a situation in which the car has zero speed but has a definite acceleration?
An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.
When a object's velocity is changing does it have acceleration?
Yes, it does.

It's position is also always changing as a result of having a velocity.
Which rate at which an object changing in position?
It is speed or velocity.
How fast an object is changing its position with time is?
Its velocity
What is continuously changing velocity due to continueously changing direction?
A rotating object.
Is it possible for an object to have zero velocity?
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
