is net force a vector or scalar?

No, force is a vector quantity, it is defined by its magnitude and direction. Common vector quantities are displacement, velocity, acceleration and force. Common scalar quantities are distance, speed, work and energy.

Explanation: Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force).

The net or resultant force acting on an object is equal to the rate of change of momentum. We can therefore say that because a net force causes an object to change its motion, it also causes its momentum to change.

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This verbal statement can be expressed in equation form as follows: a = Fnet / m.

It is an average which is the total force, divided by the amount of time that force was applied. Just like an average speed. An important observation is that it is possible that there does not exsist a single static point in which the Average force is the actual force. ... Net force is a sum value.

A net force is the sum of all forces acting on an object. A net force is capable of accelerating a mass. For instance, if the wheels of a car push it forward with 5 Newtons and drag is 3 Newtons , the net force is 2 Newtons , forward. Motion to the right is positive. Motion to the left is negative.

Answer: Speed is not a vector quantity. It has only magnitude and no direction and hence it is a scalar quantity.

As an example if you have a two second time period in which the first second there was 2 newtons of force, and the second there was 0 newtons of force, your average force would be 1 newton per second, even though there was never 1 newton of force applied to the object. Net force is a sum value.

Vectors have many real-life applications, including situations involving force or velocity. For example, consider the forces acting on a boat crossing a river. The boat's motor generates a force in one direction, and the current of the river generates a force in another direction. Both forces are vectors.

Scalar and vector quantities. A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

Scalar quantities are defined by a magnitude with no applicable direction. In contrast, vector quantities must have both magnitude and direction of action. Some common scalar quantities are distance, speed, mass, and time. Some common vector quantities are force, velocity, displacement, and acceleration.

In equation form, this is Wnet=Fnetdcosθ where θ is the angle between the force vector and the displacement vector.

If two forces act on an object in opposite directions and they don't exactly cancel, what is left over is the net force (the difference in the forces). In the diagram at left, the net force is 2 Newtons to the right. If two(or more) forces act on an object in the same direction, the net force is the sum of the forces.

The net force is equated to the product of the mass times the acceleration. ... The acceleration is directly proportional to the net force; the net force equals mass times acceleration; the acceleration in the same direction as the net force; an acceleration is produced by a net force. The NET FORCE.

The net force is a term used in a system when there is a significant number of forces. If N is the number of forces acting on a body, the net force formula is given by, FNet = F1 + F2 + F3….

Work is a scalar because it is the "dot" product of 2 vectors, also called the scalar product. W can also be expressed in terms of the components of the force and displacement vectors. Work is a vector because you multiply a force (a vector) by distance (a vector).

The dot product of two vectors is a scalar because it was the part of the quaternion product that was a scalar. The cross product of two 3-vectors is a vector because it was the part of the quaternion product that was a vector.
