# data[].attributes.body
is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International . The mass of an object can be calculated if the force and the acceleration are known.

# data[].attributes.body
force, acting on an object, will change its velocity by changing either its speed or its direction or both.

# 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 speed of something in a given direction.

# data[].attributes.body
a vehicle's capacity to gain speed within a short time.

: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

# 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
states that an object at rest will stay at rest and an object inmotion will stay in motion with the same speed and direction unless acted upon by unbalanced force.

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

"a lubrication system that reduces friction"

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

# 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.
