Speed, Velocity, Acceleration
This is the formula for speed.
What is distiance divided by time?
What is mass?
The amount of matter in an object.
The process of liquid changing to gas.
What type of energy is the energy of motion?
What is Mrs. Martin's husband's name and what is his profession?
Jeff, pilot
This is the difference between speed and velocity.
velocity includes the direction an object is traveling
What is weight?
The measure of the pull of gravity on an object.
What is condensation? Name one example.
Windmills, hydrodams, solar panels, etc
What are the names of Mrs. Martin's dogs?
Bug and Bear
An object moves at a constant speed, but changes direction. Is it accelerating?
Yes because acceleration includes changing directio.
What force causes objects to fall toward Earth?
Gravity
Which process changes liquid water into water vapor?
Evaporation
What is the 4th state of matter???
What type of animal does Mrs. Martin want to have in her yard? (There are 3 possible answers)
llama, highland cow, black-kneed sheep
When does an object accelerate?
Acceleration occurs when speed changes, direction changes, or both.
Why would an astronaut weigh less on the moon than on the Earth?
There is less gravity on the moon, so the pull of gravity is less.
Condensation happens when heat is being added or removed?
removed/cooled
What type of energy does a ball have at the TOP of a ramp?
Potential
Where was Mrs. Martin born?
Houston, Texas
If a car slows down while moving forward, is it accelerating?
Yes. Slowind down is a change in speed, so it is accelerating.
Which changes when you go to space: mass, weight, or both? Explain.
Mass does not change. Weight changes depending on the amount of gravity.
Explain how evaporation and condensation are connected in the water cycle.
When heat is added to liquid, evaporation occurs. As the water vapor rises, it cools. Thermal energy is transferred away and the water vapor (gas) turns back into a liquid through the process of condensation.
Billy Bob walks 250 miles in 5 hours. What is his speed?
50 mph
What is Mrs. Martin's favorite drink?
COKE ZEROOOOOO BABY!
