Newtons First Law

Objects with greater _________ also have greater inertia.

• speed
• mass
• temperature
• friction

Which model has greater gravitational attraction (if any)

• Model A
• Model B
• Both Model A and Model B (same gravity)

One object has twice as much mass as another object. The first object also has also twice as much...

• velocity
• gracitational acceleration
• inertia
• all of these

The amount of matter in an object is 

• pressure
• weight
• mass
• force

The wheels on a moving skateboard most likely experience ____________.

• Rolling Friction
• Sliding Friction
• Fluid Friction
• Static Friction

As mass increases, what happens to the gravitational force?

• It increases.
• It decreases.
• It stays the same.
• It acts as a 3rd degree derivative function.

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

• inertia
• kinetic energy
• vector
• net force

Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a _________acts on them.  

• force
• velocity
• inertia
• acceleration 

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity

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
