• Forces that do not have physical contact between two objects

• Forces related to gravity only

Which of the following is a field or non-contact force?

Newton's first law of motion is also known as (a)   .

• The law of gravity
• The law of inertia
• The law of acceleration
• The law of force

According to Newton's first law of motion, what will happen to an object at rest if it is not acted upon by an unbalanced force?

• It will move at a constant velocity

• It will accelerate

• It will remain at rest

• It will decrease in mass

What does inertia refer to?

• The tendency of an object to accelerate

• The tendency of an object to remain at rest or in motion unless acted upon by an unbalanced force

• The tendency of an object to decrease its velocity

• The tendency of an object to increase its mass

What is mass a measure of, according to the text?

• Acceleration

• Force

• Inertia

• Velocity

What is the state of equilibrium for an object according to the text?

• When the object is accelerating

• When the sum of the forces is not equal to zero

• When the object is at rest or moving with a constant velocity because the sum of the forces is equal to zero

• When the object is acted upon by an unbalanced force

According to Newton's second law of motion, the acceleration of an object is directly proportional to what?

• The mass of the object

• The velocity of the object

• The force applied to the object

• The inertia of the object
