# Force and mass relationship

### Newton's Second Law

The first one solves for the net force when the mass and acceleration are given. Unit relationships. After going through the above slideshow, one might wonder. Develop the relationship between mass and acceleration in determining force In physics, a force is any influence that causes an object to undergo a certain. Force equals mass times acceleration, or f = ma. This is Newton's second law of motion, which applies to all physical objects.

Although it looks simple at first glance, the law has several important implications, including how objects move on Earth and in space. Fundamental laws such as this have allowed scientists to investigate nature accurately and engineers to build machines that work.

Meaning of Force Force is a physical quantity you deal with in everyday life. It takes force to open a door, lift a child, or crack an egg.

It is a pull or push exerted by one object on another; the objects can be anything from protons and electrons all the way up to planets and galaxies. The pull or push may come from direct contact or, in the case of gravity, electricity and magnetism, from a distance. Scientists measure force in units called newtons, where one newton is the force needed to accelerate a 1-kilogram mass one meter per second squared.

## Forces, mass and acceleration

Acceleration comes only from a change in speed. When an object gains speed, its acceleration is positive; when speed is lost, acceleration is negative. You measure speed in units of distance divided by time, such as miles per hour or meters per second. Acceleration is the change in speed divided by the time the speed takes to change, so it is meters per second per second, or meters per second squared.

Sciencing Video Vault Meaning of Mass The mass of an object is a measure of how much matter it contains.

A rubber ball has less mass than a lead ball of the same size because it has less matter in it, fewer atoms and fewer of the protons, neutrons and electrons that make up the atoms. Mass also resists the effort to push or pull it; a ping-pong ball is easy to pick up and toss; a garbage truck is not. The truck is more massive than the ping-pong ball by many thousands of times.

## The Mighty F = ma

Consider the two oil drop diagrams below for an acceleration of a car. From the diagram, determine the direction of the net force that is acting upon the car. Then click the buttons to view the answers.

If necessary, review acceleration from the previous unit. See Answer The net force is to the right since the acceleration is to the right. An object which moves to the right and speeds up has a rightward acceleration. See Answer The net force is to the left since the acceleration is to the left.

An object which moves to the right and slows down has a leftward acceleration. In conclusion, Newton's second law provides the explanation for the behavior of objects upon which the forces do not balance.

The law states that unbalanced forces cause objects to accelerate with an acceleration that is directly proportional to the net force and inversely proportional to the mass.
