Kinematics
What is a scalar quality?
A quality that doesn’t require direction
What is Newton’s First Law?
An object at rest remains at rest and object in motion remains in motion unless acted on by an unbalanced foce.
What is the work equation?
W=fd (force x distance )
What is the highest point of a transverse wave called?
a crest
The protons and neutrons are in the ________.
nucleus
What is the velocity equation?
Velocity equals displacement over time
What is equillibrium?
When all the net forces on an object are equal to zero.
What is potential energy?
Energy being saved to be used later.
What is refraction?
Refraction is when a wave bends around a medium.
What is the equation for Coulomb‘s Law
F=kq1q2/r^2 or electric force is G times charge 1 times charge 2 divided by the distance squared.
What is the displacement equation.
Displacement is x2-x1

What is inertia?What is it the same as ?
Tendency for something to resist motion;mass
What are the two scenarios when momentum is conserved?
1.No force/work
2.All forces are from potential sources
What is resonance?
Vibrations at an object’ natural frequency that lead to larger and larger vibrations.
Describe charging by induction.
When two charges are brought close to a conductor the charges attract and repel creating a dipole.
