Can there be a force if there is no acceleration?

If acceleration is zero, there is no force. If F=ma, and F is force, and m is mass and a is acceleration, then if acceleration is zero, then mass is irrelevant. (Zero times anything = zero). If acceleration is zero (times mass, which equals zero), then obviously force must also be zero.

What happens when an object has zero acceleration?

Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.

What happens if there is no force on an object?

If an object experiences no net force, its velocity will remain constant. The object is either at rest and the velocity is zero, or it moves in a straight line with a constant speed.

Can an object with no net force accelerate?

Newton’s First Law: If no net force acts on an object it remains at rest, if initially at rest, or it maintains its velocity if initially in motion. Newton’s Second Law: F = ma: The net force F acting on an object with mass m and acceleration a is given by this expression.

How is it possible for two or more forces to act in an object without accelerating it?

6 Answers. Acceleration happens when the net force on an object is not zero. You can apply as much force as you like to an object and it won’t accelerate if something else is applying an equal and opposite force.

Can an object have zero acceleration with only one force acting on it?

If only one force acts on an object, the object cannot have zero acceleration (Newton’s second law). It is possible for the object to have zero velocity, but only for an instant. For example (if we neglect air resistance), a ball thrown up into the air has only the force of gravity acting on it.

Under what circumstance can an object have zero acceleration but non zero velocity?

Anytime the velocity is constant, the acceleration is zero. For example, a car traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.

Can you have a zero acceleration but non zero velocity?

Acceleration is the rate of change of velocity of an object with respect to the time over which this change occurs. It is possible to have a non-zero value of acceleration when the velocity of a body is zero. At this point, the velocity of the ball is zero yet its acceleration is equal to g=9.8m/s2.

Can an object have velocity but no acceleration?

It is possible to have a non-zero value of acceleration when the velocity of a body is zero. At the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to g=9.8m/s2.

When there is zero net force acting on an object no forces at all or all forces balanced to produce zero net force then?

so objects with constant velocity also have zero net external force. This means that all the forces acting on the object are balanced — that is to say, they are in equilibrium. This rule also applies to motion in a specific direction.

Can an object experience two or more forces and not accelerate?

Forces always cause objects to move. An object can experience two or more forces and not accelerate. A contact force results from the physical contact between two objects. A field force results from the action of two objects which are positioned some distance away.

Can an object move without accelerating?

No! Ignoring friction, if something is moving at constant velocity there is no acceleration. In other words, no force is required to keep it moving. The object is moving without acceleration.
