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 1/6-th 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 1/6-th 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 non-moving 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 5-kg 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 non-accelerating 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
