Q:

# What is net force?

A:

### Quick Answer

A net force is the remaining force that produces any acceleration of an object when all opposing forces have been canceled out. Opposing forces decrease the effect of acceleration, lowering the net force of acceleration acting on an object.

### Full Answer

In nature, every force is opposed by other forces, such as friction or opposing gravitational forces. Forces can produce acceleration only if they are greater than the total opposing forces. If a force pushes an object but is matched by friction, the object does not accelerate. Likewise, if a force pushes against gravity but is less than the gravitational force on an object, it does not accelerate. For example, if a 15-Newton push on an object is opposed by a 10-Newton friction force, the object accelerates as if pushed by a 5-Newton net force without friction.

• A:

The formula for calculating net force is the mass of the object multiplied by the acceleration. This formula is commonly written as "F = ma", where "F" represents the net force, "m" represents the mass and "a" represents the acceleration.

• A:

To calculate the net force, or unbalanced force, of a Newtonian object, find the sum of all forces presently acting upon it. These include gravity, friction and other forces depending on the scenario. You need only a few figures and computations to calculate an object's net force, which is required for acceleration and is expressed in Newtons.

• A:

The equation for determining the net force acting on an object is F = ma, or force equals mass times acceleration. Net force is measured in terms of acceleration, which means a change in velocity. If there is no change in velocity, the net force is considered to be zero.
