If F=0 then velocity is constant.In summary, according to Newton's 2nd Law, if a constant force acts on an object and the mass remains constant, the acceleration will also be constant. If the net force is not big enough, the object may not move. However, if the net force is positive, the object's velocity will change.

If a constant force acts on an object, does the acceleration changes or velocity changes?

What does Newton's 2nd Law tell you?

If you put a constant force on a object siting on the ground, it may not move because your force is not big enough.

What if the net force is positive. What then?

## \vec a = \frac{\vec F}{m}##
according to this formula (Newton´s II law) if sum of all forces (F) is constant and mass m is constant ,then also acceleration a is also constant.

since ##v=\int (dt \cdot a(t))=\int (dt \cdot F(t))/m## if F≠0 then velocity changes.
 

1. What is acceleration?

Acceleration is the rate of change of velocity over time. It is a measure of how quickly an object's speed or direction is changing.

2. How is acceleration related to force?

Acceleration is directly proportional to the force acting on an object. The greater the force applied, the greater the acceleration will be.

3. What is the equation for acceleration?

The equation for acceleration is a = F/m, where "a" is acceleration, "F" is force, and "m" is mass. This equation is known as Newton's Second Law of Motion.

4. Can an object have acceleration without a force acting on it?

No, an object cannot have acceleration without a force acting on it. According to Newton's First Law of Motion, an object will remain at rest or in motion with a constant velocity unless acted upon by an external force.

5. How does acceleration change with a constant force?

If a constant force is applied to an object, the acceleration will also be constant. This means that the object will experience a steady change in velocity over time.
