If I drop a ball off a cliff, how fast will it be traveling after
two seconds.
What is 20 m/s.

What is the conservation of momentum?
What is momentum is neither created or destroyed. If a group of objects exerts forces only on each other, their total momentum does not change.
200
What is the atomic number of carbon?

How is force related to weight and how is it different?
What is force is measured in newtons and force is measured in newtons. Weight equals mass times the acceleration to gravity. Force equals mass times any acceleration.

Why is it harder to start a car rolling than it is to keep it rolling?
What is static friction is stronger than rolling friction.
300
Why do objects look like they are floating in space? Remember at 400 km above the surface, gravity is still 90% of what it is at the surface of the earth.
What is that the objects are in free fall, moving around the earth.

An elephant and an ant have the same momentum. Which animal is traveling faster.
What is the ant?
300
What is a person's average reaction time in our lab?
What is around 1/10 to 2/10 of a second.
400
As force increases what happens to the acceleration of an object.
What is increase.
400
A micro-weld does what?
What is the small imperfections on a surface that cause friction.
400
In the reaction time lab we tried to catch a meter stick as soon as we saw it fall. How did we determine the reaction time. Ie. What data did we collect to figure this out.
What is distance and acceleration due to gravity.

What is newton's 3rd law?
What is for every action force, there is an equal and opposite reaction.
