2. 1 - $100 Which object has the most inertia? A 10 kg rock
A bundle of feathers with a mass of 20 kg
A 5 kg book
A 15 kg bowling ball B

3. 1 - $200
Which statement about a bowling ball that has a mass of 15 kg on Earth is true?
The bowling ball has more mass on Earth than it does on the Moon
The bowling ball has less mass on Earth than it does on the Moon
The bowling ball’s mass is the same on both the Earth and the Moon.
The bowling ball would have no mass in space C

4. 1 - $300
A baseball with a mass of 1 kg is thrown at 100 m/s and a football with a mass of 5 kg is thrown at 5 m/s. Which statement is true?
The football has more inertia because it has more mass
The baseball has more inertia because it is moving at a greater velocity
The baseball has more inertia because its has greater momentum
They both have the same amount of inertia A

5. 1 - $400 Inertia ___________. Is determined by the weight of an object
Is determined by the shape of an object
Is greater for objects with less mass
Is an object’s natural tendency to resist change in motion D

6. 1 - $500
Which statement about a bowling ball with a mass 15 kg is true?
The bowling ball will have greater weight on the Moon than on Earth
The bowling ball will have greater weight on Earth than on the moon
The bowling ball’s weight will be the same on Earth and on the Moon.
The bowling ball will have a weight of 15 kg in space B

7. 2 - $100 C Newton’s 1st Law of motion states that:
An object in motion can only stay in motion when a constant force is applied to it.
An object at rest will stay at rest and an object in motion will remain in motion unless acted upon by a balanced force.
An object at rest will stay at rest and an object in motion will remain in motion unless acted upon by a unbalanced force.
An object in motion will eventual come to a stop if the forces acting on it are balanced C

8. 2 - $200
A book is pushed across a table and comes to a stop. Which statement most accurately describes why the book stops?
The presence of inertia causes the book to stop
The natural tendency for an object is to eventually come to a stop
Because no force is being applied to keep the book moving
The presence of an external frictional force causes the book to stop D

9. 2 - $300 If a rock in space is thrown what would happen to the rock?
It would move at a constant velocity and direction because no forces are acting on it
It would eventually come to a stop because the forces are unbalanced
It would move at a constant velocity because unbalanced forces are acting on it
The rock would continue to increase in speed A

10. 2 - $400 Which scenario best describes Newton’s 1st Law in action?
A skateboarder flies forward when the skateboard hits a rock
A book sits at rest on a table
A car travelling to the right is slowing down due to an unbalanced force being applied to the left
All of the scenarios demonstrate Newton’s 1st Law D

11. 2 - $500 Why does the planet Earth rotate on its axis?
There is a constant force acting on planet Earth.
The materials that make up Earth were already rotating when Earth formed.
The Sun is rotating around Earth which causes night time and day time
None of the Above B
