# Acceleration force and mass relationship

### Force, Mass, Acceleration | Zona Land Education

Sep 26, Newton's Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.”. The numerical information in the table above demonstrates some important qualitative relationships between force, mass, and acceleration. Comparing the. changes its motion. Second Law: Law of Force and Acceleration. The second law describes the relationship between force, mass, and acceleration. When mass.

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. You can have large masses, tiny masses and in-between masses. Scientists call simple quantities scalars because one number will describe it.

Force and acceleration, however, are more complicated. They have both a size and a direction. A TV weather forecaster, for example, talks about a wind coming from the west at 20 miles per hour. This is the velocity speed vector of the wind. To fully describe a force or acceleration, you need both the amount and the direction.

Push on an object of a certain mass, and it accelerates based on the amount of force and mass. A small force with a large mass results in a slow acceleration, and a large force with a small mass gives a fast acceleration.

## Newton's Second Law

A force of zero on any mass gives zero acceleration. Keep in mind that several forces can be involved at the same time.

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.

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.

### Relationships between acceleration, force and mass

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.
