IPC: Forces and Newton’s Law

The upward force exerted on an object falling through air is .

• terminal velocity

• momentum

• air resistance

• weightless

When an object moves in a circular path, it accelerates toward the center of the circle

as a result of .

• terminal velocity

• momentum

• centripetal force

• friction

The statement “to every action there is an equal and opposite reaction” is .

• the law of conservation of momentum

• Newton’s first law of motion

• Newton’s second law of motion

• Newton’s third law of motion

The product of mass and velocity gives a quantity known as .

• momentum

• friction

• inertia

• velocity

When a rocket lifts off, its upward momentum is matched by the downward

momentum of .

• nothing

• hot gases expelled by the rocket

• air pushed out of the way by the rocket

• the launch pad

A feather will fall through the air more slowly than a brick because of .

• acceleration

• air resistance

• terminal velocity

• momentum

is the tendency of an object to resist a change in motion.

• Friction

• Inertia

• Static

• Gravity

The relationship among mass, force, and acceleration is explained by .

• Newton’s first law of motion

• Newton’s second law of motion

• Newton’s third law of motion

• the conservation of momentum

is a force that opposes the motion of objects that are sliding past each other

• Air resistance

• Gravity

• Static friction

• Rolling friction

The gravitational force exerted on an object is called the object’s .

• mass
