Net Force is the overall force acting on an object, taking into account both magnitude and direction. It is calculated by adding all individual forces acting on an object together.
Net Force and mass are directly proportional. This means that as mass increases, so does the net force, and vice versa. This relationship is described by Newton's Second Law of Motion: F = ma, where F is the net force, m is the mass, and a is the acceleration.
Yes, net force can be negative. This means that the forces acting on an object are in opposite directions, causing a decrease in overall force. In other words, the object is being pulled or pushed in two opposite directions at the same time.
The angle between the direction of the force and the direction of motion affects the net force. If the angle is 0 degrees, the force is acting in the same direction as motion, resulting in maximum net force. As the angle increases, the net force decreases, reaching 0 when the force and motion are perpendicular to each other.
The unit for net force is Newton (N). It is a combination of units for mass (kg) and acceleration (m/s^2), meaning 1 N = 1 kg * m/s^2.
