Newton's Laws of Motion

Front

If you double the mass of an object with the same force applied on it, the acceleration will: double, cut in half, the same, zero

Back

cut in half

Front

What kind(s) of objects have inertia? Options: all objects with mass, only objects at rest, only objects in motion, only objects whose motion is being changed

Back

all objects with mass

Front

Which one needs a greater net force to move, a kilogram of feathers or a kilogram of iron?

Back

same

Front

After a cannonball is fired into frictionless space, the amount of force needed to keep it going equals?

Back

zero, since no force is required to keep it moving.

Front

What is the relationship between acceleration, net force, and mass of an object?

Back

All of the above: Acceleration is inversely proportional to the mass of the object, directly proportional to the magnitude of the net force, and in the same direction as the net force.

Front

A 10-kg brick and a 1-kg book are dropped in a vacuum. The Fg (weight) on the 10-kg brick is: 10 times as much as the force on the 1-kg book, zero, the same as the force on the 1-kg book, none of the above.

Back

10 times as much as the force on the 1-kg book

Front

A book weighs 4 N. When held at rest in your hands, what is the net force on the book?

Back

0 N.

Front

A 20 kg bike accelerates at 10 m/s². What is the net force?

Back

200 Newtons

Front

When a cannon fires a cannonball, which force is the reaction force? Options: The cannon moving forward, The cannonball moving forward, The cannon moving backward, The cannonball moving backward

Back

The cannon moving backward

Front

Which one of Newton’s Laws of Motion best explains why the dishes do not move when the table cloth is removed?

Back

Newton's 1st Law
