Unit 1a Cycle 1: The Universe
The area outside of Earth's atmosphere where there is no air is called a vacuum.
What is the outer space?
The bouncing of light off a surface.
What is reflect?
What is repel?
A push or a pull in a given direction.
What is force?
When objects are balanced.
What is equilibrium?
The curved path an object takes when moving around another.
What is orbit?
To get bigger.
What is waxing?
To pull together.
What is attract?
Unit of force.
What is a Newton?
When the net force equals zero, the object's motion remains unchanged.
What is a balanced force?
The third planet from the sun within our solar system.
What is the Earth?
To get smaller.
What is waning?
The invisible force field that surrounds a magnet.
What is magnetic field?
When an object speeds up or changes direction.
What is acceleration?
When the net force does not equal zero.
What is an unbalanced force?
The amount of time it takes Earth to make one complete revolution.
What is a year? (365 days)
When the moon passes into Earth's shadow and the Earth blocks the sun's light from reaching the moon.
What is a lunar eclipse?
A tool used to detect magnetic fields.
What is a compass?
When an object slows down.
What is deceleration?
Energy of motion.
What is kinetic energy?
What is inertia?
When the moon passes directly between the Earth and the Sun casting a shadow onto Earth which blocks sunlight from reaching that part of Earth.
What is a solar eclipse?
The flow of electrons (electricity) through a wire.
What is a current?
The object will move at the same speed during each time period.
What is constant velocity?
Stored energy often in how far an object is off the ground.
What is potential energy?
