Only one force acts on an object can the object have zero acceleration or zero velocity?

It is not possible for acceleration to have zero acceleration because the force acting on the object is gravity and g=9.8m/s squared. Gravity is the acceleration
It can however have a zero velocity

∙ 14y agoNo, because the net force will create an acceleration of the object.
This situation is improbable though even a ball not moving has 2 forces acting upon it, its weight force F=mg and the reaction force (The force the earth applies on the ball)
Hope that helps.

∙ 10y agoGosh, that's no trick at all. If an object's velocity is zero, for any length of time
no matter how small, then its acceleration during that time MUST be zero. There's
no other choice.
Wiki User
∙ 12y agoOf course. Force produces acceleration, not velocity. If there are no forces
acting on an object, then the object's acceleration is zero, and it continues
indefinitely with unchanged velocity ... meaning constant speed in a straight line.
Wiki User
∙ 13y agoYes, an object can have a velocity of zero and an acceleration of zero. It's an object with a velocity of zero and no net applied force.
Wiki User
∙ 11y agoVelocity is defined as the rate at which an object changes its velocity; therefore if there is zero velocity then acceleration is neutral as well.

Is it possible for many forces to act on an object and still have zero acceleration?
Wiki User
∙ 13y agoNo on acceleration and yes on velocity

When velocity may change?
Velocity can only change if the object experiences an acceleration. Acceleration can only change if either the Force on the object increases, or the Mass of the object decreases.
Three things that can be acceleration?
Only one thing can be acceleration; the changing velocity of any given object. That's what acceleration is. Acceleration is caused by a net force on the object.
When An object speeds up it has what acceleration?
For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).
Is forces always result in motion?
No. Only a NET FORCE can result in an acceleration, and thus change the velocity of an object.
The rate of change of an objects position is?
Acceleration occurs when the velocity of an object changes. Velocity is the speed and direction of an object. Newton's Second Law of Motion defines what happens when a force acts on an object. The object accelerates in the direction in which the force is acting. A force acting on a stationery object starts it moving. A force acting on a moving object will speed it up, slow it down, or change the direction in which it is movingDefinition of deceleration: (physics) a rate of decrease in velocityDefinition of acceleration: (physics) a rate of increase of velocityProps to Google :)

Why is it useful to know net force?
you can the effect of the net force in the object motion

No. Only a NET FORCE can result in an acceleration, and thus change the velocity of an object.
What can cause the velocity of an object to change?
Acceleration is a change in the speed of an object (contrary to popular belief - acceleration ban be an increase or decrease in speed). Velocity of an object only changes when acted on by an external force like a push, friction or other force. Objects in motion stay in motion until acted on by an external force
How is force a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

Is the acceleration due to gravity always pointing vertically downward even for an object whose velocity is vertically upward?
Acceleration only depends on the direction of the applied force and is independent of the velocity of the object, so gravity is always pointing down.

This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude).

A force that acts on an object does only when the object moves?
A force will produce acceleration when the object moves. force in the line of motion will increase the acceleration and the force opposite to the line of motion will decrease the acceleration.
