The unit scientists use to measure the strength of a force.
Newton
The resistance of motion when one object rubs against another.
Friction
When unequal forces act on an object causing it to move.
Unbalanced force
Newton’s first law of motion
An object at rest will stay at rest and an object in motion will stay in motion, unless acted upon by an unbalanced force.
What happens to a substance when its thermal energy decreases?
The particles move faster and they eventually change states of matter.
Newton’s second law of motion
Acceleration of an object equals the net force acting on the object divided by the object’s mass.
Anything that produces a push or pull on an object.
Force
The work that a given force can do.
Energy
Newton’s third law of motion
Every action has an equal and opposite reaction.
What is an example of a longitudinal wave?
sound
The highest point of a wave.
Crest
The fundamental force that is caused by charged particles and describes the actions of both electricity and magnetism.
Electromagnetic force
The transfer of heat through direct contact with a material such as when the heat of a fire is used to cook food in a metal frying pan.
Conduction
The waves of electromagnetic energy radiating through space.
Electromagnetic radiation
The smallest recordable type of electromagnetic radiation that carries discrete amounts of energy and momentum.
Photons
The measurement of how many waves pass a point in a certain amount of time.
Frequency
A measure of the distance between a line in the middle of a wave and its crest or its trough.
Amplitude
The energy an object has due to its motion.
Kinetic energy
The lowest point of a wave.
Trough
What is potential energy?
The energy stored in an object due to it's position.
Waves that have particles which move perpendicular to the wave motion.
Transverse waves
The average kinetic energy of the moving particles in a substance.
Temperature
The distance from the crest of one wave to the crest of the very next wave.
Wavelength
The total of all kinetic and potential energy of the atoms in an object.
Thermal Energy
what is an example of a transverse wave?
light
