You don't, if there's only one force involved. When there are two or more, then the net force is the result of the strength and direction of each one.
For example, if I push a shopping cart forward and you push it backward with exactly the same force, the net force is zero and the cart doesn't start moving.
What else can I help you with?
What two things do you need to know in order determine the amount of work you do?
You need to know the force applied and the distance over which the force is applied in order to determine the amount of work done. Work is calculated as the product of force and displacement in the direction of the force.
What two pieces of information do you need to descride force?
The direction and stength of a force can be represented by an arrow. The arrow points in the direction of the force.
Determine the magnitude and direction of total force?
To determine the magnitude and direction of the total force, you need to consider the individual forces acting on an object. To find the total force, you can sum up the individual forces vectorially. The magnitude of the total force is the length of this resultant vector, and the direction is the angle it makes with a reference axis (e.g., the x-axis).
What is needed to change the direction of a moving mass?
To change the direction of a moving mass, you need to apply a force in the opposite direction to the mass's current velocity. This force can come from various sources such as friction, gravity, or an external force like pushing or pulling. The magnitude and direction of the force will determine how quickly and effectively the mass changes its direction.
How can one determine the net force acting on an object?
To determine the net force acting on an object, you need to add up all the individual forces acting on the object in the same direction and subtract any forces acting in the opposite direction. The net force is the overall force that influences the object's motion.

The illustration shows Beatrice pushing on a heavy box Beatrice pushes with a force of 40 N How can you determine if Beatrice is doing work on the box?
To determine if Beatrice is doing work on the box, we need to know the distance over which she is pushing and the direction of the force she is applying. Work is done when a force is applied in the direction of motion over a distance. If Beatrice is pushing the box in the direction of motion over a distance, then work is being done on the box.
What is needed to change the speed of an object?
To change the speed of an object, you need to apply a force to it. The magnitude of the force and the direction in which it is applied will determine how the speed changes. If the force is in the same direction as the motion, the object will accelerate; if the force opposes the motion, the object will decelerate.
What 3 thing do you need to know to determine velocity?
To determine velocity, you need to know the object's speed (how fast it is moving), the direction in which it is moving (velocity is a vector quantity with magnitude and direction), and the reference point or frame of reference from which the velocity is being measured.
What needs to be applied in order to change an objects velocity?
To change an object's velocity, you need to apply a force to it. The force will cause the object to accelerate, thus changing its velocity. The magnitude and direction of the force will determine the extent and direction of the velocity change.
What must you know to determine speed?
To determine speed, you must know the distance traveled and the time taken to cover that distance. Speed is calculated as distance divided by time. You may also need to know the direction of motion if you want to determine the velocity, which includes both speed and direction.
What do you need to have to change speed for force acting on?
To change the speed of an object under the influence of a force, you need to apply a net force in the direction of the desired acceleration. This force must overcome any opposing forces affecting the object's motion, such as friction or air resistance. The magnitude and direction of the force applied will determine the resulting change in speed.
Why is force considered a vector quantity?
Force is considered a vector quantity because it has both magnitude and direction. This means that in order to fully describe a force, you need to know not only how strong it is, but also in which direction it is acting.
