# Physics Unit 1 Vocab

TermDefinition
Equation a statement that the values of two math expressions are equal (indicated by the sign =).
Law A rule describing a relationship that always works in the same way under the same conditions.
Frequency the number of occurrences of a repeating event per unit of time.
Oscillation movement back and forth at a regular speed
Wave Period the time it takes to complete one cycle.
Amplitude the distance from the resting position to the top of a crest or to the bottom of a trough.
Geo centrism the belief that the Earth is at the center of the Universe.
Gravity is a force that attracts a body towards the center of the earth or any other physical body having mass.
Heliocentrism the belief that the Sun is at the center of the Universe
Acceleration the rate at which velocity changes over time.
Centripetal force Any force that keeps an object moving in a circle.
Velocity a speed in a specific direction.
Terminal velocity the final, maximum velocity of the following object.
Force a push or pull’ something that changes the motion of an object.
Friction A force that resists the motion between two surfaces in contact.
Energy The ability to do work or to cause a change.
Theory a well-tested explanation of a phenomenon that is consistent with all available evidence.
Inertia the resistance of an object to a change in speed or direction of its motion.
Joule a unit used to measure energy and work.
Kinetic energy the energy of motion.
Law of conservation of energy energy is neither created nor destroyed but transformed and transferred from one form to another.
Law of conservation of momentum the amount of momentum does not change in a system as long as there is no outside force acting on that system.
Momentum a measure of mass in motion.
Motion a change of position over time.
Vector a quantity that has both size and direction.
Work the amount of energy to move an object in the direction of the force applied.
Simple Machine a mechanical device that changes the direction or magnitude of a force.
Newton's First Law of Motion a law stating that an object at rest remains at rest and an object in motion remains in motion with the same velocity and in a straight line unless acted on by an unbalanced force.
Newton's Second Law of Motion a law stating that the acceleration of an object increases with increased force, and decreases with increasing mass.
Newton's Third Law of Motion a law stating that every time one object exerts a force on another object, the second object exerts a force that is equal in size and opposite in direction back on the first object.
Equation for Frequency of a Wave f=vλ
Equation for Speed s=d/t
Equation for Acceleration a = Δv/Δt
Equation for Force F=m x a
Equation for Momentum P=mv
Equation for Work W=Fs
Equation for Kinetic Energy K.E.=1/2 m v x v
Equation for Gravitational Potential Energy U=mgh
Equation for Second Law of Motion F= m x a
Equation for Newton's Universal Law of Gravitation F=G m1 m2/r2

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
