TOEFL IBT – Physics

Vocabulary is promordial in order to improve your TOEFL score. Remember, Preparation is the key to succeed !

This vocabulary will be useful if you ever take a physics course in school, for expanding your English vocabulary, or especially for any number of English language exams you may take. Here we will look at the most commonly used words in the field, along with their French translations.

acceleration	the rate at which the velocity of a body changes with time	We achieved this acceleration over a distance of less than one millimeter.	l’accélération
balanced force	equal force acting on an object in different directions	The balanced forces are inward gravitational force and an outward force due to the pressure gradient within the star.	la force équilibrée
centripetal force	a force that causes an object to move in a cycle	The centripetal force demanded by the curved motion is also shown above.	la force centripète
energy	the capacity of a physical system to do work	Its energy could change the rate at which the universe expands.	l’énergie
force	push or pull on an object	Although it survived, gravitational forces shattered it into several pieces.	la force
free fall	when the only force acting on an object is gravity	All these objects are in free fall, not zero gravity.	la chute libre
friction	the force between two rubbing surfaces	The Teflon reduces the friction of the skin against the sock.	la friction
gravity	the force that pulls objects towards each other	A sink drains because gravity pulls the water through the pipes.	la gravitation
inertia	Newton’s first law of motion that states that an object in motion stays in motion	But inertia, however, has it leaning in that direction.	l’inertie
kinetic energy	the mechanical energy that a body has by virtue of its motion	When transferred to the arrow it is referred to as kinetic energy.	l’énergie cinétique
Law of Conservation of Energy	the law that states that energy cannot be created or destroyed but can be changed from one form to another	In the table scenario, I apply the Law of Conservation of Energy.	la loi des économies d’énergies
momentum	the product of a body’s mass and its velocity	Yet the momentum for an alternative force seems durable this time.	l’élan
motion	the state in which one object’s distance from another is changing	Sandy sets the wheels in motion, but then backs out.	le mouvement
net force	the overall force of an object	But the tension is not the same as the net force.	la force nette
Newton’s second law of motion	the acceleration of an object depends on the mass of the object and the amount of force applied	Newton’s second law of motion states that F=ma, or force equals mass times acceleration.	la seconde loi de mouvement de Newton
Newton’s third law of motion	for every action there is an equal and opposite reaction	While he did not specify that these forces be equal, it was still an early version of Newton’s third law of motion.	la troisième loi de mouvement de Newton
potential energy	the mechanical energy that a body has	Fuel contains potential energy realized by burning it to drive an engine.	l’énergie potentielle
speed	the distance an object travels per unit of time	The increased speed induces disturbances in the Earth’s magnetosphere.	la vitesse
terminal velocity	the maximum speed possible while free falling	The terminal velocity has nothing to do with the bullet’s initial velocity.	la vitesse finale
velocity	a speed in any direction	The stunt is controlled by a computer that manages wind velocity.	la vitesse
