Lab: Newton's Laws of Motion — Unit test Answers

Which refers to an object’s resistance to any change in its motion?

Scientists launch a rocket, and they monitor its acceleration and the force exerted by its engines. As the rocket gets higher, the monitors show that the acceleration of the rocket is increasing but the force exerted stays the same. How do Newton’s laws explain why the scientists could expect this to happen?

Which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?

Tyler and his family drove from Atlanta to Baltimore. They traveled a total of 678 miles over 2 days.What is the reference point in this scenario?

What kind of acceleration occurs when an object speeds up?

The diagram shows organisms a diver observed during an ocean dive.

Katie rolls a toy car off the end of a table.Which path will the car follow when it leaves the table?

The information in the table represents the effect of the mass of two objects on the gravitational force between the two objects.Which number should be in the cell with the question mark?

A relationship exists between gravity, mass, and distance. The greater the mass of the objects, the greater the gravitational force between them. The greater the distance between the objects, the weaker the gravitational force between them.

is the distance traveled during a specific unit of time.
