Define enertia
The tendency of an object to remain at rest, or in a constant motion in a straight line unless it is disturbed.

What is true of inertia?
All objects have inertia
Any object with mass has inertia
A more massive object has more inertia than a less massive object

Big Bubba has a mass of 100 kg on the earth. What is Big Bubba's mass on the moon where the force of gravity is approximately 1/6th that of Earth's? ________ Explain or show your work.
Little Billie weighs 360 N on Earth. What is Little Billie's mass on the moon where the force of gravity is approximately 1/6th that of Earth's? ________ Explain or show your work

Consider Newton's first law of motion to determine which of the following statements are true?
 Newton's first law of motion is applicable to both moving and nonmoving objects
 It would take an unbalanced force to cause an object to accelerate from rest

the following statements are true of the concept of force
 A force is a push or pull exerted upon an object which results from the interaction of that object with its environment
 An object can experience a force and not accelerate
 A contact force results from the physical contact between two objects

Newton's second law of motion true statements
 If an object is accelerating to the right, the net force on the object must be directed towards the right.
 If an object is moving to the right and slowing down, then the net force on the object is directed towards the left.
 An object has an acceleration of 8 m/s/s. If the mass of the object is increased by a factor of 4, then the new acceleration would be 2 m/s/s
 An object has an acceleration of 8 m/s/s. If the net force acting upon the object is increased by a factor of 2 and the mass of the object is increased by a factor of 4, then the new acceleration would be 4 m/s/s
 An object has an acceleration of 8 m/s/s. If the net force acting upon the object is decreased by a factor of 2 and the mass of the object is increased by a factor of 4, then the new acceleration would be 1 m/s/s.
 An object has an acceleration of 8 m/s/s. If the net force acting upon the object is increased by a factor of 4 and the mass of the object is increased by a factor of 2, then the new acceleration would be 16 m/s/s.

True or false?
An object which is moving rightward has a rightward force acting upon it

The anount of net force required to keep a 5kg object moving rightward with a constant velocity of
2 m/s is ____.a. 0 Nb. 0.4 Nc. 2 Nd. 2.5 Ne. 5 N

True or false?
For an object resting upon a nonaccelerating surface, the normal force is equal to the weight of the object

According to Newton's third law, every force is accompanied by an equal and oppositereaction force. The reason that these forces do not cancel each other is ____.
the two forces act upon different objects; only forces on the same object can balance each other
