Definitions
Some may define this as speeding up, but really, it is defined as any change in velocity.
What is acceleration?
According to Newton's Third Law, every one of these has an equal and opposite reaction.
What is an action?
This German-born physicist is best known for his Theory of Relativity.
Who is Albert Einstein?
This is the type of force applied on an object that causes it to fall down to the ground.
What is gravitational force?
Simply put, the height of a wave.
What is amplitude?
This measurement is defined as the amount of matter in an object.
What is mass?
This is also known as Newton's First Law.
What is the Law of Inertia?
Likely the most famous equation in the world, it's sometimes called the Mass-Energy Equivalence equation.
What is E=mc2?
When you set an object on the table, this force pushes up on the object.
What is normal force?
Number of oscillations per unit of time.
What is frequency?
Contrasting with kinetic energy, this is energy possessed by an object simply because of its relative position.
What is potential energy?
According to Newton's Second Law, this is equal to mass times acceleration.
What is force?
The theory of relativity describes the relationship between time and this.
What is space?
This force is at play when you pull or push an object.
What is applied force?
Also called compression waves, this type of oscillation moves particles in the same direction.
What is a longitudinal wave?
The flow of electric charge, measured in amperes.
What is current?
This toy, made of suspended metal balls, demonstrates conservation of momentum and energy through collisions.
What is a Newton's Cradle?
Written as c, or 3x108 m/s, it's as fast as it gets.
What is the speed of light?
This force happens when you slide an object along the floor.
What is frictional force?
Constructive or destructive, the amplitudes of two waves combine.
What is interference?
The rate at which work is done, or energy is transferred.
What is power?
If an object is not in motion, the forces acting upon it are said to be in this state.
What is equilibrium?
This force is responsible for the curvature of spacetime around massive objects.
What is Gravity?
This force acts toward the center of motion, but perpendicular to velocity, when an object is moving in a circle.
What is centripetal force?
In the electromagnetic spectrum, these waves have the longest wavelength.
What are radio waves?
