Relationship of mass and force

What is the relationship between force and acceleration mass? | How Things Fly Mass is a measure of the amount of material in an object, weight is the gravitational force acting on a body (although for trading purposes it is. and that acceleration is inversely proportional to mass when net force is This is more compactly written as an equation that combines these relationships. The size of the acceleration depends upon the force applied and the mass of the object. There is a relationship between force, mass and acceleration (force. 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.

Newton's Second Law

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. 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 standard unit for mass is the kilogram, about 2. Scalars and Vectors Mass is a simple kind of quantity. Acceleration is inversely proportional to mass. Whatever alteration is made of the net force, the same change will occur with the acceleration. Double, triple or quadruple the net force, and the acceleration will do the same.

On the other hand, whatever alteration is made of the mass, the opposite or inverse change will occur with the acceleration. Double, triple or quadruple the mass, and the acceleration will be one-half, one-third or one-fourth its original value.

The Direction of the Net Force and Acceleration As stated abovethe direction of the net force is in the same direction as the acceleration. Thus, if the direction of the acceleration is known, then the direction of the net force is also known.

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.

Newton's Second Law

If necessary, review acceleration from the previous unit. See Answer The net force is to the right since the acceleration is to the right.

Relationship between Gravitational Force and mass / distance.

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.
