Water cycle
What is the process called when liquid water turns into water vapor?
Evaporation
What type of energy does a moving object have?
Kinetic energy
What does speed measure?
How fast something moves.
What is motion?
A change in position over time.
Name one form of precipitation.
Rain, snow, sleet, or hail
What is the process called when water vapor cools and forms clouds?
Condensaton
Does a parked car have kinetic energy? Why or why not?
No, because it is not moving.
What is the formula for speed?
Speed= Distance/Time
True or False: An object can be moving even if it looks still from your point of view?
True
Which has more kinetic energy: a fast bike or a slow bike?
The fast bike
What is it called when water falls from clouds as rain, snow, sleet, or hail?
Precipitation
Which has more kinetic energy: a running student or a walking student?
The running student
If a student runs 100 meters in 20 seconds, what is their speed?
5 meters per second
What force slows objects down when they rub against another surface?
Friction
If you travel 50 miles in 2 hours, what is your speed?
25 miles per hour
What is collection in the water cycle?
Water gathering in oceans, lakes, rivers, or puddles.
What happens to kinetic energy when speed increases?
Kinetic energy increases.
Which is faster: 10m/s or 15m/s?
15m/s
What is inertia?
The tendency of an object to resist changes in motion
What part of the water cycle forms clouds?
Condensation
What provides most of the energy that drives the water cycle?
The sun
Which has more kinetic energy: a bowling ball rolling slowly or a tennis ball rolling quickly?
Usually, the bowling ball because it has more mass.
If a car travels 240 miles in 4 hours, what is its speed?
60 miles per hour
What happens to an object's motion if no forces act on it?
It will keep moving at the same speed and direction.
Why does a heavier moving object often have more kinetic energy than a lighter moving object?
Because mass affects kinetic energy.
