What happens to an astronauts weight and mass as she travels from the earth to the moon?
What is the mass is the same but the weight will decrease because the moon has less gravity?

If a toy truck has 12 J of potential energy at the top of a frictionless ramp how much kinetic energy will it have at the bottom of the ramp?
12 J

Why didn't the note card fall down when the cup of water was turned upside down?
What is because the upward force of air is greater than the downward forces?

Explain what happens to the matter in a log when it is burned.
Some of it is transformed into ash and smoke and light and heat, but the total amount of matter and energy doesn't change.

List 3 things that were happening right after the "Big Bang" according to the Big Bang Theory.
What is there was infinite density, violence (or heat) , and rapid expansion?
400
Gold has a density of 19.3 g/cm^3 and nickel has a density of 7.81 g/cm^3. The two metals have the same mass. Which has a larger volume and why?
What is nickel because it has a lower density, because density and volume are indirectly proportional?

Position=-2m/s*time+40m What is the velocity of the object?
What is 2 m/s in the negative direction?

Describe Newton's Third Law?
What is forces between 2 objects are always equal but in opposite directions.

What is work done be friction if PE at the top of a ramp is 5.6 J and the KE at the bottom of the ramp is 3.4 J?
What is 2.2 J ?

Explain why we use parallel circuits in our buildings instead of series circuits.
What is because parallel circuits allow everything to work the way they were designed because it allows more current when more devices are turned on.
