What is the resultant acceleration

Acceleration is a vector, meaning each acceleration has both magnitude and direction. The resultant of vectors is basically the net acceleration on the object expressed as a single vector. For example, if there are two vectors each with a magnitude of 2 meters/(seconds squared) acting on an object and these vectors were placed on the x and y axes then you could represent this system of 2 vectors 90 degrees apart each with a magnitude of two meters/(seconds squared) as one vector of 45 degrees with a magnitude of 2 times the square root of 2 meters/(seconds squared).

Properties of matter are typically broken into two categories physical and

chemical

Does a cart loaded with groceries have more inertia because it has more mass than an empty cart

The law of motion that states that an object will maintain its straight line motion until acted upon by an unbalanced force is

Newtons first Law

If you add together all of the forces exerted on an object and get a non-zero value this is called

net

Velocity is the change of speed andor direction of an object

Not exactly. Velocity is the speed and direction of an object's motion.

If either speed or direction changes, then the change is the object's 'acceleration'.
