Combining Velocities Going In The Same Diretion

# data[].attributes.body
Velocity must Include the speed of an object in a particular direction.

# data[].attributes.body
The SI unit for speed is meters per second (m/s).

# data[].attributes.body
Reference points are used for determining motion. Use full reference points are non moving objects such as trees buildings and Earths surface.

# data[].attributes.body
A force that opposes mothion between two surfaces that are in contact.

# data[].attributes.body
The combination of all of the forces acting on an object.

# data[].attributes.body
The SI unit for force (Symbol, N).

# data[].attributes.body
A push or pull exerted on an object; force has size and direction.

# data[].attributes.body
The rate at which velocity changes over time; an object accelerates if its speed, direction, or both change

# data[].attributes.body
The speed of an object in a particular direction

# data[].attributes.body
The distance traveled divided by the time interval during which the motion occurred.

# data[].attributes.body
An object's change in position relative to a reference point.
