- 1. Multiple Choice
Inertia is....for every action, there is an equal and opposite reactionlarger objects take more force to movean object in motion tends to stay in motion unless acted on by an opposite forcea push that acts in the opposite direction and it slows down. - 2. Multiple Choice
This form of motion can only occur in outer space or in a vacuum. It is solely dependent on the force of gravity.
Free Fall Motion
Centripetal Motion
Projectile Motion
None of the Above
- 3. Multiple Choice

Centripetal Motion
Projectile Motion
Free Fall Motion
None of the Above
- 4. Multiple Choice

- 6. Multiple ChoiceWhat happens to the velocity of a ball as it is dropped off a cliff?It decreases at a uniform rateIt increases at a uniform rateIt is constantIt increases at a non-uniform rate
- 7. Multiple Choice
If you are Galileo answer the ff question:
"Why does a bowling ball and feather hit the ground at different times when dropped from the same height?"
They don't; they hit the ground at the same time.
One is more dense than the other.
One is heavier than the other.
Air resistance

Based from Aristotelian Physics, what was natural for planets to do in terms of their type of motion?
They orbit in elliptical motion
They orbit in triangular motion
They orbit in no particular consistent shape
They orbit in circular motion

large amount of force applied
violent motion
antiperistasis
projectile motion
- 15. Multiple Choice
