Newton's Laws of Motion
What is it called when an object resists a change in motion?
Inertia
What is the SI unit for energy?
Joules (J)
What are the states of matter?
Solid, liquid, gas, and plasma
What is a wave?
A disturbance that transfers energy through a medium, carrying something from one place to another.
What is a circuit?
They control the movement of electric current by providing paths for electrons to follow.
How do you identify the mass and acceleration of an object?
Multiply the mass of the object by the acceleration (F=ma)
What are the two main forms of energy?
Kinetic and potential
A solid is matter with a definite ____ and definite _____.
Shape and Volume
What are the two kinds of waves?
Longitudinal and transverse
What is the presence or flow of electric charges?
Electricity
What is the unit for force?
Newtons
What is kinetic energy?
The energy of motion
What would happen if you left a cup of water in the fridge for 5 hours?
It would become frozen and solid
What is frequency and how can we measure it?
Frequency is the number of waves that pass in a given amount of time. it's measured in hertz (Hz) by counting the number of crests that pass the point in 1 second.
All matter is composed of ____ and ____ particles.
Positive and negative
The reaction to an action is always ____.
____ energy is the energy stored due to an object's position
Potential
Which state of matter has the highest amount of kinetic energy?
Plasma
What is reflection?
The bouncing back of a wave after hitting a surface.
What is an electric current
The flow of charged particles
The rate of change of momentum is known as?
Force
What two variables does kinetic energy depend on?
Mass and Velocity
Which state of matter has particles that are not touching?
gas
Refraction is the slight bending of a wave as it passes between two substances.
How are series and parallel circuits similar and different
In both series and parallel circuits, energy is transferred via the flow of electrical current, but they differ significantly in how that current is distributed.
