- The relationship among mass force, and acceleration is explained by __ a Newtoris first law of motion b Newton's third law of motion conservation of momentum d Newton's second law of motion
- What does buoyancy refer to? The expansion of objects In water The pressure a fluid exerts on an object The downward force that sinks objects in a fluid The downward force that sinks objects in a fluid The force that makes things float in a fluid
- According to Newton's second law of motion, the acceleration of an object equals the net force acting on the object divided by the object's a weight. b velocity. C momentum d mass.
- When objects are moved further apart from each other, the force of gravity a decreases. b stays the same. C increases. d decreases at first and then increases.
