A student applies a 10 N force to a wood block with a mass of 5 kg. The block is pushed across four different surfaces. The accelerations of the block are recorded. Which can be concluded from the information in the table?

The block showed the least friction on Surface 3.

The block moved for the longest time over Surface 3.

The block had the greatest weight on Surface 4.

The block had the largest inertia on Surface 4.

A brick is resting on a level, smooth surface. When a student applies a horizontal force of 5 N to the brick, the force of friction on the brick is also 5 N. Which statement BEST describes the effect of these two forces on the brick?

The net force on the brick is 0 N, and the brick remains at rest.

The net force on the brick is 0 N, and the brick begins to move.

The net force on the brick is 10 N, and the brick begins to move.

The net force on the brick is 10 N, and the brick remains at rest.

The force acting on an object is decreased to half its initial value after the mass of the object is doubled. Which statement BEST describes the resulting change in acceleration of the object?

The acceleration is decreased to one-half of its initial magnitude.

The acceleration is decreased to one-fourth of its initial magnitude.

The acceleration is increased to twice its initial magnitude.

The acceleration is increased to four times its initial magnitude.

A student pushes a book with a force of 5 N to the east. Which statement describes the reaction force?

5N westward, acting on the student

5N eastward, acting on the book

5N westward, acting on the book

5N eastward, acting on the student

In the 1970s, two twin spacecraft, Voyager 1 and Voyager 2, were launched to study and explore the outer planets. Both of these spacecraft completed their missions in the 1980s, and continue to cruise their way out of the solar system. Which law of physics explains how these spacecraft continue their constant speed journey?

Newton’s Second Law of Motion

Newton’s Universal Law of Gravitation

During a magic show, a magician quickly pulls a tablecloth off of a table set with dishes without disturbing the dishes. What law explains why the dishes did not move when the tablecloth was pulled out from under them?

Newton’s Second Law of Motion

Newton’s Universal Law of Gravitation

During a fall, why does a skydiver reach a terminal (constant) velocity and not continue to accelerate?

The downward weight of the skydiver equals the upward force of air resistance on the skydiver.

The force of the skydiver on Earth is equal and opposite to the force of Earth on the skydiver.

No forces act on the skydiver during the time the terminal velocity is reached.

The downward force of air resistance on the skydiver equals the upward force of the weight of the skydiver
