Force and Motion Quiz Review

Assuming the force acting on the object is equal,

which claim about inertia and acceleration can be

supported by the data collected by the student?

• An object with a lower mass has less inertia

  which causes acceleration to decrease.

• An object with a higher mass has more inertia

  which causes acceleration to decrease.

• An object with a lower mass has more inertia

  which causes acceleration to increase.

• An object with a higher mass has less inertia

  which causes acceleration to increase.

A student is investigating acceleration and force.

The student rolls five balls of different masses

and records her observations in the table shown.What claim can the student make using this

data?

• The acceleration of an object is dependent on its

  mass.

• The mass of an object is directly proportional to

  its acceleration.

• The acceleration of an object decreases as the

  mass of an object increases.

• The amount of force required to accelerate an

  object is proportional to its mass.

Haile's plane travels forward for a few feet and

then begins to fall. What would explain the

plane's ability to travel forward for a few feet

without falling?

• The speed of the plane is equal to the speed of

  the oncoming air that pushes on the plane.

• The speed of the plane is greater than the

  speed of the oncoming air that pushes on the

  plane.

• The force of the air pushing up on the plane is

  equal to the force of gravity pulling down on the

  plane.

• The force of gravity pulling down on the plane is

  greater than the force of the air pushing up on

  the plane.

Megan left her wagon outside while it was raining

and it filled with water. When Megan tried to

move the wagon that afternoon, she failed to

budge the wagon. Why did Megan's wagon

become hard to move?

• The rainwater decreased the force of gravity

  pushing on the wagon, increasing the force

  needed to move it.

• The rainwater decreased the force of friction

  pulling on the wagon, decreasing the force

  needed to move it.

• The rainwater increased the mass of the wagon,

  decreasing the amount of force needed to move

  it.

• The rainwater increased the mass of the wagon,

  increasing the amount of force needed to move

  it.

If the force of weight, Y, on the airplane is .044 N,

then the paper airplane will move

• upward, if the force of lift, X, is half the force of

  Y.

• upward, if the force of lift, X, is double the force

  of Y.

• downward, if the force of lift, X, is double the

  force of Y.

• downward, if the force of lift, X, is the same as

  the force of Y.

A skydiver jumps from an airplane and opens his

parachute. At some point during his fall, the

downward force of gravity on the skydiver is

equal to the upward force of drag on the

parachute. Which of the following best describes

the skydiver's motion at this point?

• The skydiver is moving at an increasing speed.

• The skydiver is moving at a constant speed.

• The skydiver is accelerating downward.

• The skydiver is decelerating upward.

How is the space shuttle able to leave Earth's

surface?

• The space shuttle's engines create an upward

  force greater than the downward force of gravity.

• The space shuttle's engines create a downward

  force greater than the upward force of gravity.

• The space shuttle's engines create an upward

  force less than the downward force of gravity.

• The space shuttle's engines create a downward

  force less than the upward force of gravity.

What are the points at which Ryan’s velocity

changes? There are multiple correct answers here

• Ryan changes velocity twice at point C, each time he

  changes direction.

• He also changes velocity at E,when

  he turns around to drive back to

• his velocity

  changes at point F, when he comes to a stop and

  experiences a change in speed.

• no change
