An applied force is an interaction of one object on another that causes the second object to accelerate or change velocity or direction. The force can be a push, pull, or drag. The resulting direction of an object depends on the relative direction of the force on the object.

The net force on an object is equal to the mass of the object multiplied by the acceleration of the object. Or some simply say: Force equals mass times acceleration.

Formula of Net Force FN is the force acting on a body. When the body is at rest, the net force formula is given by, FNet = Fa + Fg.

The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero.

If two forces act on an object in the same direction, the net force is equal to the sum of the two forces.

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). If two(or more) forces act on an object in the same direction, the net force is the sum of the forces. In the diagram at left, the net force is 30 Newtons to the right.

The net force on an object is the combined effect (the sum) of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force.

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a moving object continues to move at the same speed and in the same direction.

If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This is an example of unbalanced force.

Balanced and unbalanced forces – example When an object is in equilibrium, that is, it is not moving with changing speed, the net force acting on it is balanced. For example, when an apple falls from the tree an unbalanced force equal to its weight is acting on the apple.

When two forces acting on an object are not equal in size, we say that they are unbalanced forces. a stationary object starts to move in the direction of the resultant force. a moving object changes speed and/or direction in the direction of the resultant force.

To make an object accelerate, there has to be an unbalanced force acting in the same direction as the acceleration. Because the forces do not cancel each other out, an unbalanced force is produced, and the car speeds up.

The three types of non-contact forces are gravitational force, magnetic force, electrostatic and nuclear force.

The four main resistance forces are objects with mass, inertia, and momentum; friction; gravity; and air resistance.

The force on an object is a product of its mass and acceleration, and since the mass of an object remains constant, it is the changes in acceleration that leads to commensurate changes in force. Therefore, when the force on an object increases, so does its acceleration.

According to Gladwell, a person could become an expert in nearly any field as long as they were willing to devote the requisite 10,000 hours to studying and practicing the subject or skill.

Answer: The measure of an object’s mass and velocity is called momentum.

In collisions between two objects momentum is conserved. Since the initial momentum is not zero, the final momentum is not zero. Both objects cannot be at rest. It is possible for one of the objects to be at rest after the collision.

What is the difference between momentum and velocity? Momentum is dependent on mass, and velocity is independent of mass. The momentum is conserved in a closed system, but the velocity is not conserved. An external force is always required to change the velocity, but momentum can be changed by changing mass.

The Main Difference Between Velocity and Acceleration Here are the basic definitions of velocity and acceleration: velocity – the rate of displacement of a moving object over time. acceleration – the rate of velocity change over time.
