Water Stuff
This force helps objects float in water.
What is buoyancy?
This force pulls everything toward Earth.
What is gravity?
This angle measures exactly 90 degrees.
What is a right angle?
This type of energy comes from heat.
What is thermal energy?
If an object is less dense than water, it will do this.
What is float?
This force slows objects down as they move through air.
What is drag?
This angle is smaller than 90 degrees.
What is an acute angle?
This type of energy comes from the sun.
What is radiant energy?
If an object is more dense than water, it will do this.
What is sink?
This is the direction gravity always pulls objects.
What is downward (toward Earth)?
This angle is larger than 90 but less than 180 degrees.
What is an obtuse angle?
This type of energy is stored in food and batteries.
What is chemical energy?
This famous scientist explained why things float or sink in water.
Who is Archimedes?
A parachute increases this force to slow a fall.
What is drag?
This angle forms a straight line.
What is a straight angle?
This type of energy is stored in the nucleus of atoms.
What is nuclear energy?
This effect is seen most commonly when an object is dropped in water
