What is the Second Law of Motion?
Acceleration depends on the object's mass and on the net force acting on the object
An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force
If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object
Inertia depends on the object's force and on the mass acting on the object
The amount of force needed to move an object is measured in ...
Kilometers
Seconds
Newtons
Grams
