Exam 2: Newtons Laws of Motion

A light woman and a heavy man jump from an airplane at the same time and open their same-size parachutes at the same time.Which person reaches a state of zero acceleration first?

A Mack truck and a Mini Cooper traveling at the same speed collide head-on.The vehicle to undergo the greatest change in velocity will be the

A heavy object and a light object in a vacuum are dropped at the same time from rest.The heavy object reaches the ground

Action and reaction pairs of forces always act on

Newton's second law focuses on

If the mass of an object does not change,a constant net force on the object produces constant

While a car travels around a circular track at constant speed,its

As drops fall from a leaky faucet they become

The air resistance of falling is greatly affected by an object's frontal area and

A skydiver jumps from a high-flying plane.As her velocity of fall increases,her acceleration

When an object falls through the air,as velocity increases the net force

A pair of tennis balls fall through the air from a tall building.One ball is regular and the other is filled with lead pellets.Air resistance just before they hit is greater for the

A pair of tennis balls fall through the air from a tall building.One ball is regular and the other is filled with lead pellets.The ball to reach the ground first is the

A constant net force on a railroad car produces constant

If you jump vertically while inside a fast-moving train that is slowing down,you land

Jake pulls on a 25-kg cart with a constant force of 50 N.What is the wagon's acceleration?

A space probe in remote outer space continues moving

A block is dragged at constant velocity across a level surface by a force of 6 N.What is the force of friction between the block and the surface?

Which object has zero acceleration?

The attraction of a person's body toward Earth is called weight.The reaction to this force is
