1
Anything that produces a push or pull on an object.
Force
The unit scientists use to measure the strength of a force. Equal to the force required to move 1 kg of mass to accelerate the speed of 1 meter per second squared.
Newton
When unequal forces act on an object causing it to move.
Unbalanced force
The highest point of a wave.
Crest
Waves that have particles which move perpendicular to the wave motion.
Transverse waves
An object at rest will stay at rest and an object in motion will stay in motion, unless acted upon by an unbalanced force.
Newton’s first law of motion
Acceleration of an object equals the net force acting on the object divided by the object’s mass.
Newton’s second law of motion
F= M x A
Rewrite this formula to solve for acceleration.
A = F/ M
The lowest point of a wave.
Trough
The smallest recordable type of electromagnetic radiation that carries discrete amounts of energy and momentum.
Photon
Every action has an equal and opposite reaction.
Newton’s third law of motion
The resistance of motion when one object rubs against another.
Friction
The fundamental force that is caused by charged particles and describes the actions of both electricity and magnetism.
Electromagnetic force
The distance from the crest of one wave to the crest of the very next wave.
Wavelength
What is a transverse wave?
A wave with particles that move perpendicular to the wave motion.
The work that a given force can do.
Energy
The energy an object has due to its motion.
Kinetic energy
The average kinetic energy of the moving particles in a substance.
Temperature
The measurement of how many waves pass a point in a certain amount of time.
Frequency
What is a longitudinal wave?
A wave that has particles that move parallel to the wave motion.
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 total of all kinetic and potential energy of the atoms in an object.
Thermal energy
The waves of electromagnetic energy radiating through space.
Electromagnetic radiation
A measure of the distance between a line in the middle of a wave and its crest or its trough.
Amplitude
Who came up with the three laws of motion?
Sir Issac Newton
