Out in Space
This is the supermassive black hole at the center of the Milky Way.
Sagittarius A*
This is when light waves bend or spread out.
Diffraction
According to the this law, if object A exerts a force on object B, object B simultaneously exerts a force of equal magnitude and opposite direction on object A.
Law of Action and Reaction
This theory suggests that measurements you make of an object can change, depending on how fast you are going.
The Special Theory of Relativity
These are particles that make up light.
Photons
What does gravity cause moons to do?
Orbit Planets
This is a branch of mathematics focused on continuous change.
Calculus
According to this law, an object will not move on its own; it needs something or someone to move it.
Law of Inertia
This theory suggests gravity is not a force; it is a curvature in space-time; anything with mass will cause space-time to bend.
The General Theory of Relativity
This is the study of the nature of the universe.
Physical Cosmology
What does gravity cause planets to do?
Orbit stars.
This uses mirrors to reflect light and form an image.
Reflecting Telescope
According to this law objects will pull on each other, and the large object will have a stronger gravitational force.
Law of Universal Gravitation
This is an equation that suggests that energy equals mass times the speed of light squared.
E = MC^2
This is a force of attraction, or pull, between any two objects.
Gravity
What does gravity cause stars to do?
Orbit Sagittarius A*.
Name two things that affect the strength of gravity.
The mass of an object, and the distance between the two.
According to this law the more mass something has, the more force is needed to move it.
Law of Acceleration
This is the idea that light is both a particle and a wave.
Wave-Particle Duality
This is the regular rise and fall of water along the shore.
Tide
Why is the moon’s gravitational pull is weaker than the Earth’s?
It has less mass.
Where did Isaac Newton get the idea of gravity?
When an apple fell on his head.
According to the laws of physics, this is the fastest possible speed. The speed of...
Light
When you ride in a car, it seems so much slower than when you watch it go by. What theory explains that?
The Special Theory of Relativity.
These are disturbances in space-time caused by accelerated masses.
