Gravity, Air Resistance, and Newton's Laws of Motion Test

The closer two objects are to each other

• the harder they will land
• have no gravitational force
• have a stronger gravitational force
• yep

As mass increases, what happens to gravitational force?

• increases
• decreases
• stays the same
• i don't know

The resistance of an object to a change in its motion is

• circumference

• inertia

• air resistance

• weight

The upward force which is exerted against a falling object is

• gravity

• terminal velocity

• air resistance

• intertia

A physical influence that acts to change the position of an object is

• force

• newton

• mass

• law

When a falling object stops accelerating and falls at a constant speed, it is

• fluency

• constant velocity

• acceleration

• terminal velocity

Units used to measure force are

• pounds

• newtons

• isaacs

• mass

Mass times acceleration equals

• inertia

• newtons

• weight

• air resistance

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
