Motion,Speed,
Acceleration
Acceleration
The rate of change of velocity
Acceleration
Objects in motion tend to stay in motion, objects at rest tend to stay at rest
Newton's first law
The smallest particle of an element that still retains the properties of the element
Atom
The energy a moving object has because of it's motion
Kinetic Energy
Thermal energy within air or liquids
Convection
The distance and object travels per unit of time
Speed
What is the 1st law referred to as?
Law of Inertia
Charged particle that has either more or fewer electrons than protons
Ion
Energy cannot be created or destroyed
Law of conservation of energy
Poorly conducts heat, it resists the flow of thermal energy and helps maintain temperature
Insulator
Includes the speed of an object and the direction of it's motion
Velocity
For every action there is an equal and opposite reaction
Newton's third law of motion
Atoms of the same element that have different numbers of neutrons
isotopes
Vibration of atoms in matter. The faster it is more heat energy develops
Thermal Energy
Thermal energy through empty space
Radiation
The distance and direction of an objects change in position from the starting point
Displacement
Why is less force needed to give an apple the same acceleration as a watermelon
It has less mass so less inertia
What subatomic particles are changing in an Ion?
electrons
Mechanical energy transmitted through solids by the vibration of an object, sound waves
Sound Energy
The amount of energy needed to raise the temperature of a specific mass
Heat
The speed shown on a speedometer is the instantaneous speed. It's the speed at a given point in time
Instantaneous Speed
To cause an object to accelerate, a force must be applied. The more force applied the quicker you accelerate
Newton's second law
What subatomic particles are changing in an atom
Nothing is changing
Stored energy due to position energy can be stored in an object. Now it has potential to cause change
Potential Energy
Efficiently transfers thermal energy due to it's high thermal conductivity, meaning it heats up and cools down quickly
Conductor
