# data[].attributes.body
an influence tending to change the motion of a body or produce motion or stress in a stationary body. The magnitude of such an influence is often calculated by multiplying the mass of the body by its acceleration.

# data[].attributes.body
a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

# data[].attributes.body
the quantity of matter that a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.

# data[].attributes.body
the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

# data[].attributes.body
the speed of something in a given direction.

# data[].attributes.body
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

# data[].attributes.body
the action or process of moving or being moved.

# data[].attributes.body
The focus of Lesson 1 is Newton's first law of motion- sometimes referred to as the law of inertia.

# data[].attributes.body
the rate of change of velocity per unit of time.

# data[].attributes.body
the resistance that one surface or object encounters when moving over another.

# data[].attributes.body
A force is a push or a pull that acts upon an object as a results of its interaction with another object.
