Destructive Interference

Front

Addition of two waves when the crest of one overlaps the trough of another, so that their individual effects cancel each other. The result is a wave of decreased amplitude.

Back

Mass

Front

A measure of the amount of matter in an object

Back

Coefficient of Friction

Front

the ratio of the force of friction to the normal force acting between two objects

Back

Torque

Front

a turning or twisting force

Back

Frequency

Front

The inverse of period. The number of cycles per second (Hz)

Back

Coulomb's Law

Front

relates two point charges and the distance separating them with the electrostatic force of attraction or repulsion.

Back

Longitudinal Wave

Front

A wave in which the vibration of the medium is parallel to the direction the wave travels

Back

Normal Force

Front

a force that acts on a surface in a direction perpendicular to the surface

Back

Momentum

Front

A quantity defined as the product of the mass and velocity of an object

Back

Newton's Third Law

Front

every force is accompanied by an equal and opposite force (action-reaction).

Back

Rotational Kinetic Energy

Front

Energy associated with the rotation of an object

Back

Center of Mass

Front

the point in an object that moves as if all the object's mass were concentrated at that point

Back

Electrostatic Force

Front

The force between electrically charged objects (like charges repel and opposite charges attract each other).

Back

Angular Momentum

Front

The momentum of a rotating object

Back

Static Friction

Front

Friction that acts on objects that are not moving

Back

Interference

Front

The interaction between waves that meet.

Back

Current

Front

A movement of electrical charges around a closed path or circuit

Back

Force

Front

A push or pull exerted on an object

Back

Superposition

Front

The principle that allows us to add and subtract wave forms that interfere with one another

Back

Tension

Front

A pulling force exerted by a rope or string

Back

Centripetal Acceleration

Front

acceleration of an object toward the center of a curved or circular path

Back

Newton's Second Law

Front

the acceleration of an object is directly proportional to the force exerted on it, and inversely proportional to its mass

Back

Kinetic Energy

Front

The energy associated with the motion of an object

Back

Newton's First law

Front

An object at rest remains at rest and an object in motion maintains its velocity unless it experiences a net force

Back

Period

Front

The time for one cycle of an oscillating object or wave

Back

Elastic Collision

Front

A collision in which the total momentum and the total kinetic energy are conserved.

Back

Doppler Effect

Front

An observed change in the frequency of a wave when the source or observer is moving

Back

Charge

Front

A measure of the extra positive or negative particles that an object has.

Back

Power

Front

The rate at which work is done

Back

Kinetic Friction

Front

the force that opposes the movement of two surfaces that are in contact and are sliding over each other

Back

Restoring Force

Front

Any force that always acts to pull a system back toward equilibrium

Back

Inelastic Collision

Front

a type of collision in which the kinetic energy after the collision is less than the kinetic energy before the collision but momentum is conserved

Back

Voltage

Front

The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit.

Back

Gravitational Potential Energy

Front

Energy stored by objects due to their position above Earth's surface.

Back

Impulse

Front

Change in momentum; the force applied multiplied by the time it is applied

Back

Resistance

Front

A material's opposition to the flow of electric current.

Back

Amplitude

Front

The maximum displacement of a wave or oscillating object from equilibrium

Back

Rotational Inertia

Front

The measure of an objects resistance to change of its rotational velocity which is dependent upon the mass of the object and the distribution of that mass

Back

Work

Front

The change in energy of a system

Back

Inertia

Front

Resistance of an object to a change in its motion

Back

Beats

Front

A throbbing variation in the loudness of sound caused by interference when two tones of slightly different frequencies are sounded together.

Back

Mechanical Energy

Front

Kinetic or potential energy associated with the motion or position of an object

Back

Force of Gravity

Front

Weight

Back

Rotational Acceleration

Front

The change of angular velocity over time

Back

Weight

Front

The force of gravity on an object

Back

Constructive Interference

Front

Addition of two or more waves when wave crests overlap to produce a resulting wave of increased amplitude.

Back

Transverse Wave

Front

A wave that moves the medium in a direction perpendicular to the direction in which the wave travels

Back

Acceleration

Front

The change in velocity over time

Back
