Energy
100
A push or a pull.
What is a Force
100
This has both a direction and magnitude.
What is a vector
100
All orbits' shapes are these.
What are ellipses
100
This states that an object at rest stays at rest, and an object in motion stays in motion.
What is Newton's 3rd Law
100
Energy of motion
What is kinetic energy
200
A diagram that shows all external forces on an object.
What is a Free Body Diagram
200
These are vectors along a coordinate plane.
What are component vectors
200
This property defines an orbit's 'squished-ness'.
What is eccentricity
200
A collision where kinetic energy is conserved.
What is an elastic collision
200
Unlike vectors, all energies are examples of these.
What are scalars
300
A force that always opposes motion.
What is friction
300
This does not affect the horizontal motion of an object.
What is gravity
300
This acceleration varies from planet to planet.
What is gravity
300
All collisions that stick together are types of these
What are inelastic collisions
300
This causes energy “lost” to heat.
What is friction
400
A state where an object is not accelerating.
What is equilibrium
400
The acceleration that points toward the center of circular motion.
What is centripetal acceleration
400
This momentum is important in creating planetary systems.
What is angular momentum
400
Average force times change in time.
What is an impulse
400
Gravitational, Kinetic, and Spring Potential energies are all examples of this.
What is mechanical energy
500
This is the only exception to a contact force.
What is the force due to gravity
500
These are the only two factors that affect a pendulum.
What are length and gravity
500
This is proportional to the square of the period of an orbit.
What is the cube of the semi-major axis
500
Ft = mv
What is the impulse-momentum theorum
500
An energy that is path independent.
What is a potential energy
