The law of inertia (Newton’s First Law) applies

• to both moving and nonmoving objects
• only to moving objects
• only to objects that are not moving

A skateboard rolls down a hill, reaches the level surface and eventually comes to a stop. The fact that the skateboard ultimately stops is best explained by ____.

• an unbalanced force would be required to keep the sled moving forward at constant speed

• the presence of an unbalanced force (e.g., friction) can cause a moving object to stop

• the presence of inertia causes it to stop

• the natural tendency of any object is to ultimately stop

List the objects in order from least to greatest inertia.

• CDBA

• ABCD

• BCDA

• CBAD

Mac and Tosh are arguing in the cafeteria. Mac says that if he flings the jello with a greater speed it will have a greater inertia. Tosh argues that inertia does NOT depend upon speed, but rather upon mass. Who is correct?

• Mac

• Tosh

• Neither

• Both

An astronaut kicks a soccer ball in outer space at a location far from significant influences of gravity and air resistance. The soccer ball will _________.

• continue in motion with the same speed and direction

• eventually stop as its inertia slowly becomes used up

• eventually stop since all objects ultimately "lose their steam"

• either a, b, or c -- depending on whether the astronaut continues to kick it

Which following is the first law of motion?

• An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.

• The force acting on an object is equal to the mass of that object times its acceleration

• For every action there is an equal an opposite reaction.
